First, the body of the electric hoist crane is very heavy, the inertia will be very large when lifting heavy objects, if the electric hoist is in normal operation, immediately reverse the brake, will make the entire motor operating mechanism produce a lot of torque, damaging to the transmission system, serious when the drive shaft is twisted, it is possible to make the body distorted.
Second, the electric hoist reverse brake will also make the gear connection system have a violent impact, damage the gear, resulting in the electric hoist equipment accident.
Third, the electric hoist reverse brake will also make the electric power machine produce a lot of torque and strong current, and seriously burn the motor.
Fourth, the electric hoist reverse brake will also cause the swing of the suspended objects in the air, causing the suspended objects to fall.
Fifth, the hazard of reversing sudden braking when the electric hoist is operating is that it can cause a sudden stop, which can result in the load falling or causing injury to the operator.
Therefore, at work, except in the case of special dangerous situations in order to avoid accidents, it is strictly prohibited to reverse the sudden brake.To prevent this hazard,it is important to use proper safety procedures and equipment,such as using a load restraint system or ensuring that the hoist is properly secured before reversing.
