When using a manual hoist for the first time, many people are not very familiar with what the knob of the manual hoist is used for. Reasonably turning the knob is a prerequisite for smooth operation of the manual hoist and the foundation for ensuring operation safety. Below, Guanhang will explain to you what role the knob plays.

The knob of the hand-operated hoist has three directions of rotation, namely up, middle, and down. When we need to carry out lifting operations, we need to turn the knob to "up" and then press the handle. At this time, the lifting chain will pull the heavy object to start lifting. When we need to lower a heavy object to a low point, turn the knob to "down" and then press the handle. At this time, the lifting chain will pull the heavy object to start descending. So what does' Zhong 'do?

When the knob of the hand-operated hoist is turned up and down, its reverse braking system is always in effect, which means that the lifting chain cannot be pulled. When the knob is turned to "center", the lifting chain is completely unloaded and can be easily and quickly pulled up and down. The main purpose of this key position is to better adjust the length of the lifting chain before lifting operations, in order to connect the lifting chain with the lifting target.

This is about the function of the three directions of the knob on the hand cranked hoist. If you want to learn more about the operation of the hand cranked hoist, please feel free to consult us at any time.
