The factors that make the chain block sway include: oblique pulling and lifting, rapid lifting, and fast lateral movement speed. Let's start with these factors.

I. when the heavy object is not directly under the chain block, it is easy to shake when the lower hook is directly hooked to the heavy object for lifting. The heavy object should be placed directly below for lifting.

II. When lifting, the heavy objects should be lifted slowly, and then accelerated after the lifting chain is tensioned and the heavy objects leave the ground.

III. when moving the weight horizontally, avoid frequent operations of accelerating and decelerating back and forth, or sudden braking when the speed is too fast, and keep a constant speed and move forward smoothly.

During the lifting operation, please try to avoid the shaking of heavy objects, so as not to cause damage to chain block or casualties.
