Introduction
mechanical drive winch
1. All shaft bearings are roller bearings, and the shaft materials are alloy steel.
2. High-precision, high-strength transmission chain, forced lubrication
3. Roller slotting. The high and low speed ends of the drum are ventilated pneumatic clutches. The brake wheel network (or brake disc) is forced to cool by circulating water, and the surface is quenched by intermediate frequency, which has good wear resistance and long service life.
4. Sprocket tooth profile by intermediate frequency quenching. The shift clutches are involute spline tooth clutches.
5. The main brake adopts belt brake or disc brake, and the auxiliary brake can be equipped with electromagnetic eddy current brake (water-cooled or air-cooled) or Eaton brake
