The power unit consists of an electric motor, reducer, clutch, brake, rope drum, and wire rope. The motor is a single-phase, magnetically coupled capacitor motor with a braking mechanism that activates power failure. It also features a thermal switch to prevent overheating and burnout. The reducer is a two-stage gear reduction mechanism, securely connected to the motor. The clutch, brake, and drum are integrated into the crane. When the clutch is disengaged, rapid descent is possible, while operating the brake controls the descent speed to prevent impact.
