Operating factors:
(1), improper lifting chain, lifting the rickety bundle caused by heavy decoupling, scattered or swing wounding;
(2), hoisting block hoisting in violation of the rules, such as overload lifting, people in the danger zone caused by the working personnel injury and equipment damage, and because the driver is not required to use the jack, limiter, brake or not according to the provisions for anchoring caused by overload, hoist, the derailment, overturning accident;
(3) collision caused by improper command and uncoordinated action.
Two, the main factors of equipment:
(1), grab the rope and other damage caused the fall at noon;
(2) and the control system of lifting equipment failure or accidents caused by the failure of safety equipment, such as brake failure caused by heavy impact and attack;
(3) the accident caused by the construction of insufficient strength, such as the tilt of the crane, the cause of the tilting moment beyond its stable torque caused by.
(4) electrical damage caused by electric shock accident.
(5) the derailment accidents of bridge crane caused by rail gnawing, super abrasion, or bending.
Three, environmental factors:
(1) equipment accidents such as thunder, tornado, tornado, typhoon, earthquake and other natural disasters, such as derailment, collapse, overturning, etc.;
(2) the collision and extrusion accident caused by the crowded space electric hoist www.jcyccrane.com
