Every year, there are different types of lifting accidents, and the causes of these accidents are also diverse. Decoupling is a common cause of lifting accidents. So what causes the lifting operation to uncouple? today Huai'an Crane Leasing Company Let's take you to know!

1、 Shake: when lifting, the weight is not perpendicular to the sling, so the weight shakes back and forth after leaving the ground, and large shaking will cause the goods to jump out of the tongue, the chain to break, the hook to break, etc., leading to the goods falling.

2、 Collision: there are a lot of sundries stored at the construction site. Collision occurs during lifting, which leads to unhooking, damage, scattering and falling off of goods.

3、 The parts are damaged and unhooked. Due to improper maintenance and other reasons, the chain hook is damaged and cracked, and the goods fall off during operation.

4、 Overload and unhooking will increase the fracture probability of slings and riggings when serious overloading occurs in the lifting operation, and may also cause the slings and riggings to slip from the hook, thus causing the goods to fall.

These conditions are the causes of decoupling during lifting operation, so attention must be paid to the hook part during lifting operation to prevent accidents.
