The danger of reversing the brakes during the operation of the electric hoist
1. The body of the electric hoist crane is very heavy. When the heavy object is running, the inertia will be very large. When the electric hoist is in normal operation, immediately reverse the sudden braking, the whole motor running mechanism will generate a large torque. Damage to the transmission system, in severe cases, the drive shaft is twisted, and the body may be twisted and deformed.
2. The electric hoist reverses the sudden braking, which will also cause the gear coupling system to be violently impacted, damage the gears, and cause electric hoist equipment accidents.
3. The electric hoist reverses the sudden braking and will cause the electric power machine to generate a large torque and a strong current, which will burn the motor seriously.
4. The electric hoist reverses the sudden braking and will cause the hanging object to swing and cause the hanging object to fall.
Therefore, in the work, in addition to the special dangerous situation in order to avoid accidents, it is strictly forbidden to reverse the sudden braking.
