Common cranes: Kneading, hitting, hooking, dropping, derailing, smashing, tipping, breaking, electric shock, etc.
Such as: the decoupling on the scene, the wire rope cracking and pumping, moving the hanging object, the wire rope hanging people, the pulley hitting people, falling from the sky, and other casualties, the offense, overturning, overtime in the process of application and equipment Equipment incidents such as hoisting and falling, equipment that is in the process of lifting work, accidentally touching the high-voltage line or the electric shock of the inductive body, and various types of operating events that occur during the protection and protection process. The primary reason for the formation of these events is the operation. Elements, equipment elements and environmental elements.

(1) The unhooking method, the unhooking formed by the loose joints, the scattered objects or the swaying injury,
(2) Violation of operating procedures; such as overloading, heavy injury and equipment damage caused by people in hazardous areas; and the use of weights, stops, brakes or irregular hoisting, anchors due to drivers not following the rules Fixed overload, over-winding, deviant, overturning, etc.
(3) Bumping and other formations caused by unreasonable command and uncoordinated measures.

(1) The spreader fails; if heavy objects such as hooks, grabs, wire ropes, nets, etc. are damaged,
(2) The failure of the operating system of the lifting equipment or the failure of the safety equipment; if the brake equipment fails, the impact and pinching of the heavy objects are formed.
(3) The incident of the strength of the component is not caused; for example, the dumping of the tower crane; the reason is that the towering moment of the tower exceeds its stability torque,
(4) The electric shock caused by the damage of the electrical appliance,
(5) Bridge cranes due to rails, super-wear, or tortuosity.

(1) Deteriorating, smashing, dumping and other equipment incidents caused by strong natural disasters such as lightning, gusts, tornadoes, hurricanes, earthquakes, etc.
(2) Due to the bumps and squeezing of the situation caused by the congestion and messiness of the place,
(3) The bumpy event caused by the lack of brightness and the blocking of the field of view.
