The lever hoist is driven by pulling the handle. Normally, this operation mode is relatively easy, but it is always difficult to pull the lever for some special reasons. What causes this? Next, Guanhang will bring you answers.
The first is that there is a serious overload. Under the effect of severe load, the internal components of the lever hoist are damaged, making it unable to ensure a stable force output.
The second is that the connection between the handle and the body of the chain block is seriously worn, and this wear is getting more and more serious in repeated pulling, resulting in greater resistance.
The third problem is the lifting chain. That is to say, the surrounding of the lifting chain in the early stage has become a problem. With the constant moving of the handle, the chain clamping and twisting of the lifting chain become more and more serious, resulting in more and more effort to pull the handle.
The above three factors are the main reasons for the increase of the resistance of the handle of the chain block. Therefore, we must pay attention in the process of using the chain block in the future to avoid such situations.
