ES Reverse the danger of sudden braking when electric hoist is working：
The body of the electric hoist crane is very heavy, and the inertia will be very large when lifting the weight of the crane. And the electric hoist reverses the brake immediately in normal operation. It will make the whole motor running mechanism produce a lot of torque and damage the transmission system. When it is serious, the drive shaft is broken and the body is twisted.
The electric hoist reverses the sharp brake will also cause the gear coupling system to have the violent impact, the damage gear, causes the electric hoist equipment accident.
The electric brakes reverse sharp brake will also cause the electric power machine to produce large torque and very strong current, serious will burn the motor.
The electric hoist reverses the sharp brake will also cause the aerial hanging thing to swing to cause the hanging thing to fall.
Therefore, in the work, except in case of special danger to avoid accidents, it is forbidden to reverse the brakes.
