The function of using a manual hoist to speed up

Hand cranked hoist is a manual lifting tool. When carrying out heavy lifting operations, the hook hooks the heavy object, and the worker adjusts the speed and repeatedly presses the handle to achieve the lifting operation of the heavy object. What is the role of the hand cranked hoist in speeding up during homework?

The speed of the hand cranked hoist is used to adjust the lifting operation of heavy objects. The lever block of the hand cranked hoist is located above the handle, under the steel ring of the handle. It has UP and DN markings on both sides. When it needs to be lifted, people can move the lever block to the UP position, and then operate the handle for lifting work. When it needs to be lowered, people can move the lever block to the DN position for lifting work. When people need to move the chain, they can place the lever block between UP and DN for lifting work.

Before using a manual hoist for heavy lifting operations, it is necessary to adjust the speed first, and then press the handle to achieve heavy lifting operations and improve work efficiency.
