Product Details

The control of lifting speed of high-quality manual chain hoists is directly related to the type of load borne by the chain, and is an important factor affecting the service life of the chain. During operation, some operators pull the chain rapidly to lift or lower loads in order to speed up progress. This operation method is likely to generate enormous impact loads. When the chain is suddenly subjected to instantaneous impact tension, its stress intensity will far exceed the normal load-bearing range. Over time, this will cause tiny cracks inside the chain, which will gradually expand and lead to fracture.

Therefore, users must strictly control the lifting speed and maintain a uniform and slow operation rhythm throughout the process. At the initial stage of lifting a heavy object, the chain should be pulled gently first. After confirming that the chain is under even stress and the heavy object is bearing the load stably, continue to pull the chain at a constant speed. During the lowering process of the heavy object, the operation should also be carried out slowly to avoid the impact on the chain caused by the rapid falling of the heavy object. Meanwhile, rough operations such as pulling the chain violently and stopping abruptly are strictly prohibited. Ensure that the chain is always under stable stress, so as to effectively avoid the fracture risk caused by impact loads.
