Shanghai Yiying Hoisting Machinery Co., Ltd. will tell you in detail that in the final analysis, the seal ring of the gearbox or the seal ring of the bearing is broken. Now that we have found the responsibility for the accident, how should we solve it? The connecting screws of the reducer are not tightened. After shutdown, tighten the screws. The sealing ring between the hoist reducer box and the cover is poorly assembled or damaged due to failure. The sealing ring should be removed for maintenance or replaced to prevent oil leakage.
