Rail gnawing inspection for mobile gantry crane

Aug 12, 2019
1. During the operation of the mobile gantry crane, the gap between the wheel rim and the rail changes significantly in a short distance, and the crane will occur rail gnawing.
 
2. By observing, if there are bright traces on the side of the rail, or with burrs in severe cases, or there are bright spots on the inside of the wheel rim, can determine that the mobile gantry crane will occur rail gnawing.
 
3. When the mobile gantry crane is running, especially when starting and braking, the crane body is biased and twisted.
 
4. When the rail gnawing is particularly severe, it will make a louder sound.
