Kinematic chain for electrical chain hoist

1. Adjustment screw
2. Hoisting gear
3. Chain sprocket
4. Motor
Motor torque path
The motor (4) rotates the axle, which makes the hoisting gear (2) helical steps turn. The gear
reducer transfers the motor power over the chain sprocket (3) to the chain, which then moves
according to the selected direction (up or down).
The assembly includes a slipping clutch (5) that allows to lift loads that correspond to 110% of
the nominal rated capacity. The slipping clutch prevents the hoist from lifting loads that exceed
160% of the rated capacity. An overload slips the slipping clutch, allowing the motor to continue
running and preventing the hoist from taking an overload that can damage the hoist.
Brake torque path
The brake (6) is always electrically disengaged when the motor (4) works. As soon the motor
stops, the brake engages and blocks the rotation of the hoisting gear components and the chain
sprocket.
