2, Hight-strength galvanized steel rope. With breaking force of 1870kn/mm2, it’s not necessary to get it coated with rustproof oil and maintenance-free.

3, Lifting motor. It adopts the frequency conversion motor, which is optimized air-cooling type, with insulation class F and protection class IP55, and power continuity rate 40%.

4, Lifting reducer. It gets the tooth surface carburized and hardened, with hardness of HRC60, and also has been grinded or gear shaved, with light deadweight, good sealing and no leakage.

It is equipped with spring-pressed safety lock, preventing from slipping off. All pulleys use maintenance-free bearing, the design can efficiently prevent abrasion between steel rope and pulley shell. It has delicate overall structure and volume as well as nice appearance.
