Product features:
1. High load capacity: carbonization, quenching, and grounding processed.
2. Small size, light weight: compared with soft tooth face and medium hard tooth face reducer, QY series of same capacity are much lighter.
3. High efficiency, low noise, and low vibration: grounding improves precision. Tip relief enhances its overall efficiency and reduces noise and vibration.
4. Multiple driving stage: widen the center distance, decrease unit height, this meets the requirements of crane structure.
5. Convenient mounting: three-point type reducer convenient mounting type: horizontal, vertical and even of some angle.
6. both CW and CCW rotary direction.

Main technical parameters
1. Maximum circumferential velocity: 20m/s
2. Maximum spindle speed: 1500r/min
3. Maximum transmission ratio: 400
