Electric hoist reverse brake may cause damage
Some faults and accidents of electric hoist are caused by operation mistakes. Today we will understand the possible harm caused by the reverse and sharp braking of electric hoist:
The reverse and sharp brake of electric hoist will also cause the suspension to swing and cause the suspension to fall.
The trolley body of electric hoist crane is very heavy, the inertia will be very large when lifting heavy objects, and the electric hoist in normal operation, immediately reverse the brake, will make the whole motor operating mechanism produce a lot of torque, damage to the transmission system, serious when the transmission shaft torsion, may make the car body torsion deformation.
The reverse and sharp braking of electric hoist will also cause a violent impact on the gear connection system, damaging the gear and causing an accident of electric hoist equipment.Loop chain electric hoist reverse brake will also make the electric power machine produce a lot of torque and a strong current, serious will burn out the motor.Therefore, in the work, in addition to encounter in order to avoid the accident of special dangerous situation, is strictly prohibited to reverse the brakes.
