Hand pulley parts deformation reasons are there

　　It is simple, convenient and fast to lift heavy objects by hand instead of human power. Users may also notice that its parts may be deformed in the process of use. How can we avoid this situation? Golden eagle hoisting sorted out the following points, only for reference.

　　The reasons for the deformation of parts in the construction of hand-pulled hoist products are analyzed as follows:

　　1. Deformation of lifting chain:

　　The deformation of the chain is mainly caused by the daily overloading of users. The deformation of the chain should be replaced in time to avoid the risk of future use.

　　2. Deformation of hook:

　　Hook deformation is the main reason of the error use and overload use, each type of chain has its own rated load weight, hook is labelled a tool of efforts to upgrade as much, if is beyond the capacity, can let a hook on the pulling force, deformation of the hook, and one reason is that the lever hoist lifting heavy objects, binding process method is not correct, also easy to cause hook deformation. So you have to be careful not to overload and bundle the weight correctly.

　　3. Deformation of shell:

　　Shell is generally made of high-quality low-carbon alloy steel stamping, hardness is strong enough, improper use will make it sag, hand hoist in the process of use will be due to improper operation and collision with other items, resulting in the deformation of the shell sag. Moreover, the shell will also be deformed if it is severely extruded. If it is extruded, the hand-pulled pulley will sag inward, which will reduce the operating space of the parts. It is necessary to avoid this situation.

　　Before using the hand-pulled hoist in daily life, it is necessary to check whether the hand-pulled hoist is normal or not. Determine again before lifting the goods. In case of collision or deformation in operation, stop working immediately and find out the reason.
