Why is it not allowed to reverse the emergency brake during crane operation?

the body of the crane is very heavy, but it still has a limited weight. It has a large inertia during operation. If the emergency brake is reversed immediately when the crane is in normal operation, it will cause great torque to the entire operating mechanism and damage the transmission system. In serious cases, the transmission shaft may be broken, and the vehicle body may be twisted and deformed; Reverse emergency braking will also cause violent impact on the gear connection system, damage the gear, and cause equipment problems. This function is not omnipotent; Reverse emergency braking will also cause the electric power machine to produce a large torque and strong current, which will seriously burn out the motor

reverse emergency braking will also cause the 2.3 interface and program controlled overturning of the hanging objects in the air to swing and cause the hanging objects to fall. Therefore, we will briefly explain that 1. In the process of work, it is not allowed to reverse the emergency brake except in case of special dangerous situations to avoid accidents
