Safety Preparation:

Adequate safety preparations must be made before wire rope replacement. First, determine the safety boundaries of the work area and provide the staff with the necessary personal protective equipment, such as hard hats, safety shoes and gloves. Then, make sure the bridge crane is off, cut off the power, and lock it to prevent accidental start. In addition, check and ensure that other related equipment and accessories are in normal condition.

Determine the replacement time:

It is very important to choose the appropriate time for wire rope replacement. In general, wire rope replacement can be performed during production downtime or during planned maintenance to minimize disruption to production and work. At the same time, the time and human resources needed for the replacement need to be estimated in advance to ensure the smooth operation of the replacement.

Check the wire rope hoist:

Before replacing, the wire rope needs to be carefully inspected. Use professional testing instruments to detect the wear degree, broken wire and whether there are cracks and other problems of the wire rope. If the wire rope is found to have exceeded its service life or to be severely worn and damaged, it must be replaced immediately.

Unload the old wire rope:

First, professional tools are used to gradually unload the old wire rope from the pulley, reel and hook parts of the overhead crane. In the unloading process, it is necessary to ensure smooth operation and avoid accidents or loose steel wire ropes caused by improper operation. At the same time, clean the unloaded steel wire rope in time to prevent it from causing harm to other staff or equipment.

Install new wire rope:

Check the components of the overhead such as pulley and reel to make sure they are in good condition before installing the new wire rope. Then, using a suitable tool, the new wire rope is gradually threaded through the pulley and reel and attached to the hook. In the connection process, pay attention to the correct fixing method and tightening strength to ensure that the connection is firm and reliable.

Debugging and testing:

After the wire rope replacement, the corresponding debugging and testing work must be carried out. First, confirm that the installation position of the wire rope is correct, and adjust the corresponding tension and alignment. Then, load experiments and operation tests were performed to verify the normal operation of the overhead crane and the wire rope. If any abnormal conditions or faults are found, they should be repaired and adjusted in time.

Record and maintain:

After the wire rope replacement is completed, the relevant replacement records and maintenance information should be recorded. Including the replacement time, replacement reasons, the use of wire rope specifications and models. These records are very important for future maintenance and management, which can help track the usage and maintenance history of the overhead crane, and improve the efficiency and safety of crane management.
