Product description

The LKING STEEL LIMITED 6 x 37 IWRC (independent wire rope core) single-leg wire rope sling has eye-and-eye endings and a mechanical splice for lifting loads with vertical, choker, or basket configurations in general industry applications. The 6 x 37 IWRC construction contains six strands of wire rope with approximately 37 wires per strand wrapped around a separate 7 X 7 wire rope, which has seven strands with seven wires per strand, in the center of the sling. This construction provides more flexibility than a 6 x 7 or 6 x 19 wire rope sling. The wire rope construction has more abrasion and heat resistance than a web sling. This eye-and-eye sling has an eye, or loop, on both ends, and can be used with vertical, choker, and basket lifting configurations. The eyes are secured with a mechanical (also called Flemish) splice that is stronger than a hand splice. This sling has a minimum D/d ratio of 25 and meets American Society of Mechanical Engineers (ASME) specification B30.9 and Occupational Safety and Health Administration (OSHA) specification 1910.184.

Slings are used to lift heavy objects for industrial applications. Types of slings include web slings, wire rope slings, chain slings, and mesh slings. The appropriate type of sling for an application depends on the strength-to-weight ratio, flexibility and resistance to bending, resistance to abrasion and cutting, resistance to crushing, resistance to stretching, and resistance to high temperatures and other environmental stressors. Slings have one, two, three, or four legs; or a continuous loop of webbing or wire rope. Legs are support branches that extend from a single point at the top of the sling to the item being lifted so the weight of the load is distributed evenly among the branches. Slings have eyes (loops) or alloy steel fittings on the ends.

A vertical lifting configuration connects a crane hook directly to a load with a single, vertical sling, usually by means of a hook. In a choker configuration, the sling wraps entirely around the load, and one loop passes through the other to form a slip noose, or choker. In a basket configuration, the sling passes under the load and both ends of the sling connect to the crane hook. Load capacity is the maximum weight to be lifted in a vertical configuration. The capacity in a choker configuration is approximately equal to the vertical capacity times 0.8. The capacity in a basket configuration, with sling ends at a 90-degree angle, is approximately equal to twice the vertical capacity. Load capacity in a basket configuration decreases if the angle of the sling is less than 90 degrees. For example, a sling with a capacity of 2,000 lb. in a vertical configuration will have an approximate capacity of (2,000)(0.8)=1,600 lb. in a choker configuration and an approximate capacity of (2,000)(2)=4,000 lb. in a basket configuration, if the sling ends are at a 90-degree angle to the load. A wire rope sling’s capacity in a basket configuration applies only when the configuration meets the sling’s minimum D/d ratio, which is the ratio of the diameter of the rope’s curve around the load (D) to the diameter of the sling (d). If the minimum D/d ratio is not met, the capacity of the sling is decreased.

LKING STEEL LIMITED Lifting Technologies manufactures lifting solutions including slings, cranes, and hoists. Founded in 1967, the company is headquartered in Shanghai, China.

The main wire rope is an item that must be checked in the inspection. If the main wire rope is not qualified, it can be judged that the tower crane installation is unqualified. Please check yourself.

The steel wire rope is an important link in the hoisting process, and any slip or loss will lead to major events. Therefore, the inspection of steel wire rope is particularly important. TST steel wire rope flaw detection system is suitable for single person to carry, or easy to temporarily install and transfer. It can detect the static and non moving steel wire rope, and can also detect the moving wire rope.

A、 What should the wire rope check?

  1. Whether the wire is broken: the steel wire whose crack or scar has reached half of the diameter of the steel wire is regarded as broken wire.
  2. Check wear and damage: pay attention to concentric wear and eccentric wear.
  3. Corrosion: check the degree of corrosion, pitting corrosion and pitting corrosion. It is easy to corrode in rainy season in South China.
  4. Deformation: check the twist, waviness and flatness to confirm the deformation degree.
  5. Arc and heat effect: if the steel wire is found to be tempered or burnt, the wire shall be broken.
  6. Check the fastening parts of the rope end: check whether the fixed part of the rope end is pulled out or sliding due to the defects, cracks and deformation of the pressing block.
  7. At the same time, pay attention to the drum and pulley: check the wear condition at the bottom of rope groove and the rotation of pulley.

B、 In case of any of the following conditions, the wire rope shall be scrapped:

  1. For the cross-wound wire rope, the number of broken wires in a lay length (refers to the axial distance around a circle of any wire rope strand) reaches 10% of the total number of wires in the rope.
  2. The number of scrapped broken wires of wire rope for hoisting hot metal or dangerous goods shall behalf of that of the general crane, i.e. 5%.
  3. The corrosion or wear of the steel wire on the surface layer of the wire rope reaches 40% of the original wire diameter on the surface.
  4. The wire rope has obvious internal corrosion.
  5. The diameter of the wire rope is reduced by 7%.
  6. There are cracks or slip deformation at the joint between the steel wire rope and aluminum alloy; the splicing part of the spliced steel wire rope is seriously pulled off; the joint between the cast steel wire rope anchorage and the steel wire rope is displaced, resulting in the pull-out phenomenon.
  7. There are wear or corrosion on the surface of Bright wire rope and a certain number of broken wires.
  8. The whole strand is broken or burnt out.
  9. The elongation of partial outer steel wire rope is “cage” shape or the diameter of steel wire rope fiber core increases seriously.

Elevator Wire Rope from LKS

Abstract: the elevator wire rope mainly refers to the traction steel rope. The traction rope bears all the weight of the elevator, and in the operation of the elevator, it bends in one direction or alternately around the traction wheel, guide wheel or anti rope wheel. The steel rope also bears high specific pressure in the rope groove, so the steel rope must have high strength, flexibility and wear resistance. This paper analyzes the main factors affecting the fatigue life from the installation, use, maintenance and production process of the steel rope.

Elevator Wire Rope

The steel rope is a load-bearing element in the elevator, which almost bears all the weight of the elevator. The quality of the steel rope will directly affect the safety of the elevator operation. In the operation of the elevator, the wire rope is bent unidirectionally or alternately around the traction wheel, guide wheel and anti rope wheel. The steel wire rope bears high specific pressure in the rope groove, so the steel wire rope for elevator is required to have high strength, flexibility and wear resistance.

The steel rope is generally circular strand structure, which is mainly composed of steel wire strand and rope core. Steel wire is the basic component of wire rope, which requires high strength and toughness. The strand of wire rope is made of steel wire, usually 8 to 9 strands. The core is usually made of sisal fiber or synthetic fiber of alkene.

The factors affecting the service life of steel rope for elevator mainly include the following aspects: safety factor of traction steel wire rope, tensile load of steel rope, bending radius of steel rope in use, material and groove type of traction wheel, material and twisting quality of steel wire rope itself, lubrication of steel wire rope, use and maintenance of wire rope, etc.

1. Safety factor of traction wire rope

The safety factor of elevator partly depends on the safety factor of traction wire rope. There are static and dynamic loads in the operation of elevator wire rope, but the main factor affecting the service life of steel wire rope is static load. In practical application, in order to simplify calculation, only static load is considered for practical calculation. The diameter of steel wire rope for elevator is very important. In order to improve the strength of steel wire rope and prolong its service life, the diameter of steel wire rope must be the most appropriate size. For the calculation of safety factor, the corresponding safety factor is calculated according to the national approved standard by selecting the diameter of steel wire rope, so as to ensure the safety performance of steel wire rope for elevator The service life of the rope.

2. Tensile load of steel rope

The tensile load is the load that the elevator wire rope bears in the operation of the elevator and the variation in its movement. In a well maintained and debugged elevator, the load of each steel rope in the operation process should be basically the same. If the tension of each rope is uneven in operation due to improper maintenance of the wire rope, the compressive stress between one or several wire ropes and the wheel groove will be greatly increased, which will accelerate the wear of the wire rope and directly affect the service life of the wire rope. Therefore, it is clearly stipulated in the elevator supervision and inspection rules that the deviation between the traction wire rope tension and the average value is not more than 5%.

3. Bending radius of steel rope in use

The curvature radius of steel rope is determined according to the pitch diameter and relative position of traction wheel, anti rope pulley and guide wheel in the use of steel wire rope. Different positions and different pitch diameter determine the bending times and bending stress of steel wire rope in use. The bending stress is inversely proportional to the pitch diameter of each wheel. Article 9.2.1 of gb7588-1995 < Safety Code for elevator manufacture and installation > > stipulates that the ratio of pitch diameter of traction wheel, pulley or drum to the nominal diameter of suspension rope shall not be less than 40 regardless of the number of strands of steel wire rope. During the bending process of steel wire rope, the relative displacement of steel wire in the strand occurs, and there is wear inside. The greater the bending stress, the greater the contact stress between strands With the accumulation of time, the steel wire will break because of stress concentration. Therefore, under the condition that the traction capacity is satisfied, the radius of curvature should be increased as much as possible, the number of rope wheels should be reduced, the reverse bending or twisting of wire rope should be avoided, and the bending stress of steel rope should be reduced in the process of using, so as to reduce the adverse factors on the service life of wire rope.

4. Traction wheel material and groove type

4.1 the groove type and material of traction wheel are closely related to the service life of steel rope. Generally speaking, the wear of steel rope should be very slow due to its higher hardness than rope operation. However, due to the matching of the rope tension and groove type, the elevator wire rope slips, eccentric wear and roll in the groove, which causes wear with the rope groove. Generally, there are semicircular groove, semicircular groove with notch and V-groove. The contact area between the semicircular groove and the rope is relatively large, the specific pressure distribution of the wire rope in the groove is more uniform, and the wear of the rope is relatively small. In order to limit the deterioration of traction conditions due to wear, the lower part of traction wheel is often cut when the rope groove is not subject to additional hardening treatment. The specific pressure distribution of steel rope in the semicircular groove with notch is relatively concentrated, and the specific pressure increases when the notch angle increases. However, due to the small contact area between V-groove and steel wire rope, the specific pressure distribution of steel rope in the rope groove is relatively concentrated, the V-shaped angle is reduced, the specific pressure is increased, and the damage to the steel wire rope is greater in use, which affects the service life of the wire rope.

4.2 generally, the hardness and elastic modulus of the groove should be considered for the material of traction wheel. If the material with soft material is used, the external stress will be reduced, but the wear of the steel wire rope will turn to the inside of the wire rope, and the fracture of the steel wire inside the wire rope will increase. Therefore, it is suggested to use polyurethane rope groove liner on the traction wheel. The liner is embedded into the corresponding groove, and transverse grooves are processed on the liner. The friction coefficient of the appropriate grooved wheel to the non lubricated steel wire rope is almost unchanged, and the polyurethane wear resistance is also very good, which improves the service life of the liner and greatly increases the service life of the elevator wire rope.

5. Steel rope itself

Fatigue is one of the main reasons for more broken wires in the process of using elevator wire rope. The broken wire of elevator wire rope moving around traction wheel is the result of bending fatigue and wear fatigue. The research and understanding of the production process and fatigue essence is helpful to take measures in the production process, improve the fatigue resistance of elevator wire rope and prolong the service life of elevator wire rope It can reduce the operation cost and improve the safety and reliability of elevator operation.

5.1 effect of rope making steel wire

The best metallographic structure is suitable for drawing steel wire. In the production process, due to the surface damage of steel wire, or serious scratches, scars, rust pits, and non-metallic inclusions formed in the steel smelting process, it is easy to form fatigue sources. The content and particle size of non-metallic inclusions in steel have a significant impact on the fatigue performance of steel  rope, because the reticular ferrite in the metallographic structure after sorbite can promote the rapid propagation of fatigue crack, so the network ferrite is not allowed in lead quenched steel wire. The austenitizing temperature of steel wire and the isothermal transformation temperature of lead quenching determine the generation of network ferrite Qualitative influence, the automatic control furnace temperature and lead temperature technology of lead quenching production line is conducive to the uniformity of sorbite structure, and the lead liquid circulation is conducive to the uniform sorbite structure of steel wire at different positions in the lead pot, which can ensure that the strength of steel wire after lead quenching is relatively uniform, so as to ensure the minimum fluctuation range of mechanical properties of steel wire after drawing. The optimum combination of strength and toughness is beneficial to improve the fatigue resistance of wire rope. Generally, straight wire drawing machine and water box drawing machine belong to non torsion drawing, which is beneficial to obtain high strength and high toughness steel wire. The lubrication and cooling capacity of water tank is better than that of dry wire drawing machine. Larger diameter drum and tower wheel can reduce the bending deformation of steel wire winding. Multi pass low compression ratio drawing can obtain high toughness.

5.2 selection of steel rope structure

The structure of wire rope has an important influence on the fatigue resistance of steel rope. Generally, surface contact steel rope is caused by line contact wire rope, and wire contact wire rope is caused by point contact wire rope. For the steel rope for elevator, due to the limitation of service conditions and the relatively narrow space environment of elevator shaft, the traction wheel with larger diameter cannot be selected. The rigidity and flexibility of surface contact wire rope are large, because the elevator wire rope produced by forging, die drawing or rolling is rarely used. 6-strand or 8-strand wire contact wire rope is used for ordinary elevator rope, and parallel twisted wire rope is used for high-speed elevator. According to the design concept of modern steel steel rope, it is beneficial to improve the fatigue resistance of steel rope to keep proper gap between strands and layers of steel rope, but the gap between strands and ropes must be uniform. Therefore, it is very important to determine the wire diameter ratio, wire diameter tolerance and hemp core diameter.

5.3 selection of steel rope grease

The quality of grease used in steel wire rope has an important influence on the fatigue resistance of steel rope. It must be selected according to the use and environment of steel rope and the technical index of grease. The elevator wire rope is mainly used in the indoor elevator shaft. When the elevator shaft does not take temperature and humidity control measures, the internal environment of the elevator shaft is closely related to the overall environment of the area, such as low temperature and dry in the northeast, high temperature and humidity in the southern coastal area. The regional temperature and humidity are very different, so the use of steel wire rope end users must be considered when selecting grease The effect of temperature on the physical properties of oil is obvious. The lubricity of the steel wire rope should be kept as long as possible. The grease has certain high and low temperature performance. Generally, the high temperature performance is measured by the drop point of the grease, and the low temperature performance is measured by the low temperature brittleness of the grease. The selected grease should ensure that the high temperature does not drip and the low temperature does not embrittlement.

5.4 oil application method and quantity of elevator rope

In the production process of elevator wire rope, the oiling of rope strand can be generally divided into wire oiling, strand oiling and rope oiling, and the oiling methods can be divided into immersion type and spray type. According to the purpose of the production of steel wire rope to determine the oiling method, but must ensure that the oil evenly distributed on the surface of the steel wire, at the same time for the physical properties of the selected grease, twisting speed to determine the oil content to meet the requirements. Generally, too high oil temperature will lead to grease denaturation, too large amount of oil will reduce the friction between the wire rope and the traction wheel, which is easy to throw out in the process of use; too small amount of oil will reduce the lubrication performance of the wire rope and reduce the fatigue resistance of the wire rope.

5.5 selection of rope core

Most of the steel rope of elevator adopts fiber core structure, and few of them use metal core. The main function of the rope core is to support the rope strand to keep its original shape in any state. Secondly, the rope core can store grease. In the process of use, the oil source for long-term lubrication of the steel wire rope can make the steel wire well lubricated. In addition, it can improve the contact between steel wire strands and wires and reduce the impact load. Therefore, the performance of the rope core has an important impact on the service performance of the wire rope. If the rope core is too thin, the diameter of the wire rope will be reduced, and a certain gap can not be maintained between the strands; if the rope core is too thick, the diameter of the wire rope will increase and the gap between the strands will be generated; if there is a large hemp core joint, the wire rope will bulge, and the contact between the wire rope and the rope wheel will wear quickly due to stress concentration, resulting in wire breakage and strand breakage, so as to ensure the straightness of the rope core Diameter accuracy and joint control are very important. It is one of the ways to prolong the bending fatigue life of the steel wire rope by using the wire rope with high elastic core to reduce the contact stress between the strands when the wire rope bears the bending stress on the rope pulley.

5.6 Steel rope twisting process

The quality of Steel rope twisting directly affects the fatigue life of steel wire rope. The following mainly analyzes the selection and use of twisting process parameters.

5.6.1 selection of lay length

Lay distance is a very important parameter in the technical index of steel wire rope, which has a great influence on the comprehensive performance of wire rope. The size of lay distance directly affects the production efficiency of steel wire rope, the strength loss in the process of steel wire twisting, the breaking force of the whole rope, the flexibility, looseness, fatigue resistance, pressure resistance, impact resistance, structural elongation and diameter of steel wire rope. Therefore, the choice of lay distance should not be too large or too small, and the comprehensive influence of various factors should be considered.

5.6.2 use of tooling

Pre deformer and post deformer are the main fixture for wire rope production. The design of main process parameters is generally based on wire rope diameter, strand diameter and experience

According to the formula, in order to make the parameters more reasonable and scientific, combined with practical production experience and the strength level of wire rope, the process parameters are formulated respectively.

5.6.3 use of pretensioning

The main purpose of wire rope pretensioning is to partially or completely eliminate the structural elongation of steel wire rope that cannot be completely avoided in use. Proper pre tensioning treatment can eliminate the twisting defects of steel wire rope, improve the uniform distribution of tension of steel wire and wire rope strand when bearing, make the strand rope in the most stable position in structure, which is conducive to improve the fatigue strength of steel wire rope and prolong the wire rope Service life.

6. Lubrication of Steel rope

The lubrication of elevator rope can effectively reduce the friction of steel wire rope and prolong the service life of steel wire rope. Generally speaking, in the applicable places with large diameter of traction wheel and dry temperature, the steel wire rope still has enough lubricating oil after using for 3 to 5 years, and it is not necessary to add new oil. However, no matter how long it is used, maintenance lubricating oil must be added as long as rust or drying signs occur on the elevator wire rope.

7. Use and maintenance of elevator rope

The use and maintenance of elevator rope is to effectively maintain the steel wire rope after the completion of elevator installation, mainly from the following four aspects of maintenance and replacement, to ensure the safe use of elevator rope, and achieve the expected service life.

7.1 during the operation of the elevator, timely and regularly check the operation condition of the steel wire rope, mainly including the number, position and twist distance of the steel wire rope; the thinning of the wire rope diameter; the uniform tension of the wire rope; the lubrication, cleaning and corrosion of the steel wire rope; whether the assembly of the steel wire rope end has elongation or abnormal conditions.

7.2 observe the wear and deformation of the elevator wire rope during operation, and confirm whether to replace it with a new one. The phenomenon of sudden fracture of elevator wire rope under normal working conditions is rare, and its damage is generally formed in long-term operation due to wear, bending fatigue, corrosion or external damage, so timely observe the abnormal phenomenon of steel wire rope in operation to avoid unnecessary safety factors.

7.3 for the condition of elevator wire rope in rope groove, check whether the working surface of rope groove is smooth and whether the depth of steel wire rope lying in rope groove is consistent.

7.4 corrosion inspection of elevator wire rope: the elevator steel wire rope will rust during the use process, the mechanical properties will be reduced, the diameter of steel wire will become thinner, and the strands will be loose, resulting in brittle fracture. This kind of fracture is avalanche fracture, which is more dangerous than general wire breaking or wear. Regular addition of maintenance lubricating oil is a way to prevent wire rope corrosion.

Conclusion: as the most important part of elevator suspension device, elevator wire rope plays an important role in the safety performance of elevator. In the production process, the design of process parameters and the control of production process have a crucial impact on the fatigue resistance of steel wire rope. Taking measures against these factors can improve the fatigue resistance of wire rope. In the use of elevator wire rope, the correct installation and maintenance can also extend the service life of  steel rope.

Creating a reliable tension member

The quality of the steel wires used for elevator cores has a substantial impact on the service life of the rope. When running over the traction- and deflection sheaves, the wires in the rope are exposed to high tension- and flexural stresses, causing friction which will result in abrasive wear. Our elevator rope wire’s excellent mechanical properties are a solution for these issues.

Elevator Steel Wire Ropes with FC & IWRC

Steel wire ropes are one of the best choices for elevator applications owing to its two main features: redundancy and detectability as shown below:

  • Redundancy is very important for safety-relevant applications. If one of individual elements is broken, other elements will take on its function and remain in operation taking advantages of interaction between wires.
  • Detectability means the capacity to determine the end of service life and the degree of bending fatigue of running wires. As fatigue increase, more external wire breaks so that it is possible to estimate by visible inspection before the condition becoming dangerous.

Normally, elevator wire ropes feature parallel strand construction for reducing incidence of abrasion compared with ropes with cross laid construction. Meanwhile, they have a high fatigue bending life and less wear to running sheaves.

Construction:
Depending on the intended needs, two different core types are available: fiber core (FC) and independent wire rope core (IWRC).

  • Fiber core, made of natural or synthetic fibers, is widely used in ropes and makes elevator ropes easier to adjust up to the relevant groove shape. Meanwhile, fiber core provides excellent resistance against contact pressure and long-term support for elevator wire ropes.
  • Independent wire rope core effectively increases the metallic cross-section of elevator wire ropes and reduce tensile stress in individual wires. Meanwhile, steel cores low the elongation of elevator wire ropes under same loads compared with fiber core.

Normally, an elevator wire rope is composed of six, eight or nine strands with FC or IWRC as shown in the following pictures:

LKS Crane Wire Rope in 1200TONS Crane

In the afternoon of June 8, with the 350 ton crane arm slowly put back to the shelf, the installation of crane wire rope for 1200 ton pile around crane and 350 ton pile winding crane of H6018 ship was successfully completed, and the maximum work before the tilt test of the project was successfully completed.

1200 tons Crane Wire Rope
1200T Crane Wire Rope

The deck of H6018 ship is equipped with two pile winding cranes, including five 1200 ton crane wire rope, two luffing wire rope of 50 * 1500 meters, two main hook wire ropes of 58 * 2000 meters, and one auxiliary hook wire rope of 50 * 1000 meters; the 350 ton crane has three luffing wire rope of 42 * 900 meters * 1, the main hook wire rope of 42 * 1200 meters * 1, and the auxiliary hook wire rope of 42 * 300 meters * 1.

The installation of the above crane wire rope involves 690V main power supply of the crane, ballast adjustment of the ship and installation of the sliding contact line. Among them, the steel wire installation of the 1200 ton crane needs floating berthing, and the floating berthing needs to reserve a distance of 70 meters from the stern. The ship needs to be moved, and the cross operation with the pile leg is carried out, and the extreme weather is also faced…

Due to the heavy workload, complex process and many cross operations, and the ship ballast can not be used, it is difficult to adjust it manually. According to the past experience, the period needs one month, which will not meet the requirements of tilt test.

On May 20, the project team took the lead to organize ZPMC manufacturers, material department, general assembly department and other units to hold a special meeting, which launched a “battle against the clock” to ensure the node.

Retrospection

1、 Set up a temporary group to tackle difficulties and overcome difficulties

At the symposium, a temporary group for tackling difficulties was established, which was composed of project team, design department I, material department, commissioning operation area, ship loading operation area, electric loading operation area, mechanical loading operation area, technical construction method personnel, lifting workers, erection workers and other personnel. The division of labor was clear, the responsibilities were assigned to each person, and all the personnel made concerted progress;

2、 Strong plan

Formulate a special plan with the morning, afternoon and evening shift as the time points, and make it clear that the work will be completed on June 8. The node is the order, and the plan will not be relaxed;

3、 Focus on planning:

The start of the project coincides with the two sessions and the safety month. The rope threading process involves factors such as floating state adjustment, high-altitude operation, extreme weather and other factors. Therefore, it is planned to adjust the operation to the daytime. The shift is carried out at noon to race against the time. During this period, the generator characteristic test and crane cross operation, peak stagger planning is particularly critical. At 5:30 a.m. every day, the commissioning operation area is in place, the generator power supply is turned on, the Zhenhua construction personnel are in place to start operation, the machine installation personnel keep on adding water and drainage, waiting for ballast adjustment, and the gantry crane is on duty for 24 hours at any time;

4、 Dare to innovate:

Since the installation of the sliding contact line of the 1200 ton crane involves professional manufacturers, the installation cycle takes about 10 days, which can not meet the planned demand. At the meeting, it was immediately decided to use the temporary power line for bridging. In the commissioning operation area, the cable was constantly searched and collected, and the lunch break was actively given up to complete the temporary cable bridging work.

Overview of operation

From May 21 to 23, 1200 tons of electrified idling inspection and luffing crane wire rope installation

From May 25 to 31, 350 ton sliding contact line installation, medium voltage cable withstand voltage inspection, idling inspection, h6018 ship moving

From June 01 to June 06, the installation of 1200 tons of main and auxiliary crane steel wire ropes was completed

June 07-08 350 tons of main and auxiliary crane wire rope installation completed

The above series of data are created by the joint efforts of all staff of H6018 project team after half a month’s hard work, which shortens the planned one month cycle to 18 days and compresses a full 12 days.

At the beginning of 2019,LKS High performance Wire Ropes used in the lifting of “The world’s first crane”, the construction and installation site of the largest equipment (ethylene 2 propylene tower) of China Science and technology refining and chemical integration project, “the world’s first crane” challenges the hoisting of 1000 ton ethylene 2 propylene tower with the largest volume, the highest height, the largest hoisting difficulty and the highest hoisting requirements of the island refining and chemical project.

XCMG xgc88000 4000t crawler crane and 1250t crawler crane have double tail sliding. The main crane 4000t crawler crane adopts 102 main boom + 33m fixed auxiliary boom working condition, and the working radius is 34m. The ethylene 2 propylene tower with a diameter of 6.804m was successfully installed in place. The erection height is 108.6m, and the main hoisting weight is 1435t

On March 15, 2019, the “fattest” large tower of China Science and technology refinery project, the quench oil tower of 800000t / a ethylene steam cracking unit, was successfully hoisted and fixed.

On April 4, 2019, in less than 3 hours, the large ethylene tower with a height of 100 meters, a diameter of 5.2 meters and a weight of 800 tons in the ethylene refining plant of China Science and Technology Corporation jumped up in the air and stably hoisted in place.

high performance wire ropes

On June 20, 2019, XCMG xgc88000 crawler crane, the “Big Mac” combined with 500t crawler crane, successfully hoisted the absorption tower of coal to hydrogen plant, a large-scale refining equipment of China Science and Technology Corporation. The lifting equipment is the first high tower of the coal to hydrogen plant and the key core equipment of the plant, with a diameter of 4.8m, a height of about 90m and a total lifting weight of more than 800 tons.LKS High performance Wire Ropes is used for lifting.

For sure XGC 88000 crawler crane is the big guys in the lifting engineering, there is the most important we should take care is the crane wire rope,LKS specially manufactures Wire Rope for XGC 88000.Then we can see this big guy to lifting the products easily and safety.

What should be paid attention to in the use of High performance Wire Ropes?

First of all, no matter what type of High performance Wire Ropes, pay attention to the lubrication effect; if the crane wire rope is not lubricated in place and the grease cannot effectively penetrate into the wire rope strand, the wire rope will cause early wire breakage, especially the internal core after long-term wear and corrosion.

Second, the steel wire rope of the crane should pay attention to the kink phenomenon. If the special steel wire rope of the crane, such as 35W * 7 / 4V * 39s + 5FC, is not installed in place, there will be stress phenomenon at the beginning of the installation. Then the High performance Wire Ropes without rotation will also kink during the lifting of heavy objects, and some steel wire ropes will bite on the rope arranging drum.

So what if the High performance Wire Ropes head of the truck crane is treated? When installing a new steel wire rope for the crane, the two ends of the new rope shall be tied tightly with thin soft wires to prevent loose ends and strands.

So how to eliminate the kink and undercut of wire rope? In general, when the new wire rope is uncoiled, we should keep the High performance Wire Ropes in a horizontal and natural state, so as to eliminate the stress, so as to avoid the kink phenomenon and extend the service life of the wire rope when replacing the wire rope.
