Guide to troubleshooting stage chain hoist malfunctions
During stage construction and performance, a stage hoist is a commonly used lifting tool. It has the advantages of simple structure, easy operation, and high reliability. However, during use, the stage chain hoist may also experience some malfunctions. Below, we will introduce the common troubleshooting methods for stage chain hoists.
1、 The chain hoist cannot be lifted
Check if the load exceeds the rated lifting capacity of the chain hoist. If the rated lifting capacity is exceeded, the load should be reduced to within the rated range.
Check if the zipper tape is stuck or twisted. If the chain gets stuck or twisted, it should be straightened out and ensure that the chain engages correctly on the sprocket.
Check if the braking device is working properly. If the braking device fails, it should be stopped immediately and professional maintenance personnel should be contacted for inspection.
Check if the hook is damaged or deformed. If the hook is damaged or deformed, it should be replaced.
2、 Stuck during the lifting process of the chain hoist
Check if the chain is well lubricated. If the chain lacks lubrication, an appropriate amount of lubricating oil should be added.
Check whether the sprocket is worn or damaged. If the sprocket is worn or damaged, it should be replaced.
Check if the load is rubbing or colliding with other objects. If the load rubs or collides with other objects, the position of the load should be adjusted to ensure that it can be lifted smoothly.
3、 Hand pulled gourd slides down
Check if the braking device is loose or damaged. If the braking device is loose or damaged, it should be adjusted or replaced.
Check if the load exceeds the rated lifting capacity of the chain hoist. If the rated lifting capacity is exceeded, the load should be reduced to within the rated range.
Check if the chain is worn or damaged. If the chain is worn or damaged, it should be replaced.
4、 The chain of the chain hoist is broken
Immediately stop using the chain hoist and slowly lower the load.
Check the cause of the chain breakage. Chain breakage may be caused by overload, wear, corrosion, or other reasons.
Take corresponding measures to repair or replace the chain based on the cause of the chain fracture.
5、 The hook of the chain hoist is deformed or damaged
Immediately stop using the chain hoist and slowly lower the load.
Check the degree of deformation or damage to the hook. If the hook is deformed or lightly damaged, it can be repaired; If the hook is deformed or severely damaged, it should be replaced.
6、 Manual gourd operation is laborious
Check if the chain is well lubricated. If the chain lacks lubrication, an appropriate amount of lubricating oil should be added.
Check whether the sprocket is worn or damaged. If the sprocket is worn or damaged, it should be replaced.
Check if the load exceeds the rated lifting capacity of the chain hoist. If the rated lifting capacity is exceeded, the load should be reduced to within the rated range.
In short, when using stage chain hoists, we should strictly follow the operating procedures, regularly inspect and maintain the chain hoists, promptly detect and eliminate faults, and ensure the safe and reliable operation of the chain hoists. If encountering unsolvable faults, professional maintenance personnel should be contacted in a timely manner for repair.
