Steel wire rope is an important safety device for elevators, which carries the weight of the elevator and passengers or goods. Therefore, it needs to be regularly inspected and maintained, and replaced when necessary. This article will introduce the specific steps for replacing steel wire ropes.

1. Prepare tools and equipment

Before replacing the steel wire rope, necessary tools and equipment need to be prepared, such as steel wire rope, manual double wheel winch, groover, electric smooth leather pliers, work gloves, protective caps, etc. At the same time, it is necessary to clean and inspect other parts of the elevator to ensure that the replaced wire rope can be used normally.

2. Remove the elevator load-bearing framework

Before replacing the steel wire rope, it is necessary to first remove the elevator load-bearing framework. At this point, it is necessary to inspect the elevator and if other problems arise, they need to be addressed. For example, if rust is detected on the elevator casing, cleaning and anti-corrosion treatment should be carried out first.

3. Install a new wire rope

After completing the inspection and confirming that there are no issues with the elevator, proceed with the replacement of the steel wire rope. Firstly, it is necessary to deliver the elevator carriage to the top of the elevator. On one side of the top crossbeam, use a manual double wheel winch to pull back the old steel wire rope, cut open the protective sleeve, and then completely remove the old steel wire rope.

Next is the installation of the new steel wire rope. Use a groover to create a storage groove at the bottom of the new steel wire rope, thread the new steel wire rope terminals into the top of the elevator, install them on the wheel axle, and use electric leather pliers to press the terminals tightly. Check if the connection of the new steel wire rope is secure. If there are no problems, continue to connect the carriage with the new steel wire rope. Use a manual double wheel winch to pull the top of the steel wire rope back to the top, and place a new protective sleeve on the steel wire rope.

4. Binding steel wire rope

After completing the installation of the new wire rope, it is necessary to bind the wire rope. Send the carriage to the bottom, manually twist the double wheel winch and rope wire, and use a crane to remove the damper. Then use a manual double wheel winch to tighten the wire rope, place the damper back, and finally use a crane to reassemble all parts and bind the wire rope to ensure it is secure and reliable.

5. Inspection and Testing

After completing the replacement of the steel wire rope, conduct inspections and tests to confirm whether the installation is correct and ensure that each safety function of the elevator is normal. This includes checking the steel wire rope, such as conducting strength and load tests on the steel wire rope. After confirming that there are no problems, use standard test blocks to test the elevator's operating function, including smoothness and speed.

In short, when replacing the steel wire rope, it is necessary to pay attention to safety and ensure that each step is carried out according to the process and standards. Before replacement, it is necessary to prepare necessary tools and equipment, and complete the inspection and maintenance of other parts of the elevator before starting the operation. During the replacement process, each detail should be carefully checked to ensure that the wire rope is securely connected and properly bound. Step by step operation, complete the replacement step by step, and finally complete the inspection and testing to ensure that the elevator can operate safely and smoothly.
