Hand cranked haws may seem simple in structure and easy to operate, but once operated improperly, various problems can arise. Today, Guanhang will discuss with you how to operate hand cranked haws more reasonably.

Firstly, we must ensure that the heavy object is lifted by pulling the handle when it is directly below the hand-operated hoist. The purpose of doing so is to prevent the heavy object from being lifted vertically upwards without any lateral shaking.

Secondly, it is strictly prohibited to lift quickly. Before lifting, the lifting chain should be in a relaxed state. At this time, we can shift the block to the neutral position, manually tighten the chain, and then shift it to the up gear for acceleration.

Thirdly, lateral traction should be speed controlled. When we move heavy objects laterally, we should avoid frequent acceleration and deceleration back and forth operations, or sudden braking when the speed is too fast. We should maintain a constant speed and move forward smoothly.

These are the things we need to pay attention to when operating the hand cranked hoist, to ensure the rationality of the operation, in order to ensure the safe and smooth progress of lifting operations.
