Potential Issues in the Operation of Pneumatic Winches:

Air Leak Risks: Pneumatic winches require compressed air to function. If there are air leaks in components such as air pipes or pneumatic elements, it can cause the winch to suddenly drop, leading to serious accidents.

Explosion Risks: During the use of pneumatic winches, if the internal machine contains a mixture of oil and gas that has not been properly handled, a spark from operator negligence can result in an explosion.

Accidental Injury Risks: Pneumatic winches are dangerous lifting equipment. During operation, if the operator does not promptly repair faults or operates incorrectly, accidents such as uncoupling, falling, or crushing injuries can easily occur.

Insufficient Lifting Capacity: This could be due to various reasons such as excessive wear and tear on the air motor piston rings, large gaps in compression air leaks, inadequate intake pressure, improper supply lines, small pipe diameters, insufficient airflow, and excessive pressure loss.

Difficulty Starting or Operating: This may be caused by improper assembly of the piston connecting rod and casing after repair, or failure to engage the clutch.

Abnormal Impact Sounds during Air Motor Operation: This could be due to excessive wear gaps between the connecting rod small end and large end, or wear on the crankshaft rolling bearings.

Brake Failure: This may be caused by the brake band being too loose.
