The chain hoist is driven by manpower. In order to save labor, some people use mechanical equipment to drive. Is this driving feasible?

It is forbidden to use any power other than human power to control the chain hoist, because when the chain hoist is in use, operators need to observe its operation status at all times to avoid uncontrollable situations. The strength and speed of the chain block when lifting heavy objects cannot be accurately controlled by machinery. Some operations need to be adjusted at all times according to the operation conditions, which cannot be accurately achieved by machinery.

If there are some unexpected situations in the lifting process, such as chain knot and heavy object shaking, machinery can not solve them, but manual operation can be adjusted at any time, which can easily solve these problems, effectively avoid accidents and improve the safety of operation.

Therefore, when we use the chain hoist, we cannot use any power other than manpower to control the chain hoist, so as to ensure that we can use it safely and efficiently.
