The solution to the problem of "wire rope electric hoist rail gnawing" can be considered from the following aspects:

1、 Problem analysis

The phenomenon of wire rope electric hoist track gnawing is usually caused by various factors, including but not limited to insufficient track installation accuracy, uneven wheel wear, uneven track surface, and improper adjustment of the gap between the track and the wheel. These issues can lead to abnormal friction and collision between the wheels and the track during driving, resulting in wear and tear on the track.

2、 Solution

Check and adjust the track installation

Ensure that the installation accuracy of the track meets relevant standards, including levelness, straightness, and verticality.

Check if the fixing components of the track are secure to avoid any deviation caused by looseness of the track.

Check and adjust the wheels

Check the wear of the wheels and replace those with severe wear.

Ensure that the diameter and width of the wheels are consistent to avoid rail gnawing caused by differences in wheel size.

Adjust the gap between the wheels and the track to maintain appropriate contact area and contact pressure.

Improve the surface quality of the track

Clean the debris and dirt on the surface of the track to maintain its cleanliness and smoothness.

Perform necessary polishing and repair on the surface of the track to eliminate defects such as unevenness and burrs.

Adjust the operating parameters of the electric hoist

Adjust the operating speed, acceleration, and deceleration parameters of the electric hoist according to the actual situation to avoid rail gnawing caused by being too fast or too slow.

Ensure that the braking system of the electric hoist is working properly to avoid rail biting problems caused by untimely or excessive braking.

Strengthen maintenance and upkeep

Regularly maintain and upkeep the electric hoist and track, including lubrication, fastening, and replacement of vulnerable parts.

Establish comprehensive maintenance and upkeep records to promptly identify and address potential issues.

Consider using track anti gnawing devices

Install anti bite devices on the track, such as anti bite strips, anti bite plates, etc., to reduce direct contact and friction between the wheels and the track.

3、 Precautions

Before carrying out any maintenance or adjustment work, be sure to cut off the power and ensure that the electric hoist is in a safe state.

Maintenance and adjustment work should be carried out by professionals with relevant qualifications and experience.

Regular inspection and maintenance of electric hoists and tracks are important measures to prevent rail gnawing.
