Wire rope is widely used in various kinds of lifting and transportation of large mechanical equipment, but after long-term use, due to excessive stress and the influence of external factors such as wear and tear, damage and wear of wire rope is easy to happen. Once found the wire rope damage, need to change in time, in order to ensure the safety and normal operation. The following is the replacement of wire rope steps:

1. Check the wire rope damage type

Before the replacement of wire rope, it is necessary to accurately determine the type and location of damage of steel wire rope, according to different damage, and adopt measures to the corresponding change. Check whether there is wire rope fracture, foreign bodies, winding, the phenomenon such as corrosion, wear and tear, sliding kink, change in order to determine the way and time.

2. Select the appropriate wire rope

Old change new steel wire rope, wire rope should be based on the workload of the equipment, the use of environmental and other factors, such as rope, choose the right wire rope. Check the model of new steel wire rope, material, strength, corrosion resistance and other performance whether conform to the requirements of the equipment, and according to the specified length cut off, and set aside.

3. With spare ropes fixed equipment

In the process of replacement of wire rope, it is necessary to use spare ropes to temporary fixed equipment, in case the equipment move or sliding. Temporary line respectively fixed on the device and the pivot point on the ground, to ensure stable fixed.

4. Install the new wire rope

When installing a new steel wire rope, should be the new cable head installed on the equipment hook or stents, then following the original route through the rope pulley, wire rope and pulled by a worker to assist and adjust the lanyard to the appropriate location.

5. New fixed rope

After installed the new steel wire rope, need to use pliers to steel wire rope tied to the equipment, guarantee the stability of steel wire rope, strengthen fixed, at the same time check whether the wire rope is installed correctly, no looseness and foreign body.

6. A load test

After the replacement of wire rope, should further load testing, to ensure the normal work of the new steel wire rope can absorb equipment load. Through the steps to check the quality and effect of replacement of wire rope, and within the scope of the requirements gradually increase the load, until meet the requirements of equipment work.

All in all, wire rope replacement is a very important work, must be vigilant and cautious. When changing, should according to actual condition and standard procedures, choosing the appropriate line material, check the wire rope damage type, check whether the new wire rope is conform to the requirements of the equipment, so as to ensure the success of the replacement of wire rope and safety.
