The body of the bridge crane is very heavy, and the inertia is very large during operation. When the bridge crane is running normally, the emergency brake is reversed immediately, which will cause the entire operating mechanism to generate a large amount of torque and damage the transmission system. In severe cases, the transmission shaft may be broken, and the car body may be skewed and deformed. It may also have a violent impact on the gear coupling system, damage the gear, and cause equipment accidents. Reversing the emergency brake will also cause a large torque to the electric machine And very strong current, severely burns the motor.
Reversing the sudden brake will also cause the hanging in the air to swing and cause the hanging to fall. Therefore, in the work, except for special dangerous situations in order to avoid accidents, reverse quick braking is not allowed.
