Analysis of injuries in the form of lifting operations

1. heavy fall
Spreader or lifting container is damaged, tied object is not strong, the hook properly, electromagnetic sucker suddenly lost power, parts of it lifting mechanism (especially brake failure, wire break), and this will lead to heavy fall. In the high position of the object has potential energy when falling, potential energy into kinetic energy quickly, the 40 ton crane load accidental drops, or damage to the metal structure of the crane, fall, it could have serious consequences.
2. Instability tipping crane
Crane instability, there are two types: one is due to improper operation (such as overloading, luffing or rotating too fast, etc.), not leveling legs or foundation settlement and other reasons tipping moment increases, resulting in tipping crane; two is due to the slope or wind loads, so that the crane along the road surface or sliding track, causing the derailment upset.
3. Squeeze
Crane track on both sides lack a good or safe passage between the lack of structures and adequate safe distance, the metal structure of the body to run or rotating pinch injuries to personnel; operational errors or failures caused by brake operation mechanism to slip, causing grind pressure damage and so on.
4. be dropped
When it is working from the ground than 2m in height 30 ton crane installation, disassembly, inspection, maintenance or operation of other operations, damage caused by falling from a height.
5. shock
Power lines in the vicinity of the crane operation, any of its components or high-voltage electrified body hanging objects too close or touching charged objects induced charging, can lead to electrical shock.
6. Other injuries
Other injuries refers twisted body and moving parts caused by the contact, grind, stamp and other injuries; hydraulic components of hydraulic overhead cranes damage caused by high pressure liquid injection injury; damage against flying objects; handling hot liquid metal, flammable, toxic, corrosive and other dangerous goods, due to the drop rickety bundling or packaging damaged due to injury and the like.
