1. Core parameters
Rated load: 20 tons
Lifting height: 9 meters (standard configuration, can be customized according to working conditions)
Working level: M4-M6 (suitable for medium to heavy load conditions)
Lifting speed: 0.5-5 m/min (usually equipped with dual speed or variable frequency speed regulation, low speed gear can be switched for precision operations)
2. Gear Reducers
It adopts three-stage helical gear reduction. The gears and shafts are made of alloy structural steel, and their reliability and life are guaranteed through appropriate heat treatment. The box body and box cover are made of cast iron, with good vibration reduction and reliable sealing.
3. Wire Rope Drum
The drum is made of cast iron or seamless steel pipe, and the power is transmitted to the drum by spline. The outer shell is welded with steel plate. One end of the drum is connected with the lifting reducer and motor, and works with the suspension device through the wire rope; the other end is equipped with a height limit device.
