QY Series Crane Gear Reducers
Features:
1. High carrying capacity
2. Small size and light weight
3. High efficiency, low noise and low vibration. The overall efficiency of each gear is 0.98
4. Adopt multiple stages to reduce the single-stage speed ratio, open the center distance, reduce the height of the reducer, and meet the requirements of various crane mechanisms; the maximum nominal transmission ratio of the reducer reaches 400
5. Three fulcrum reducer, which can be installed vertically, horizontally or even at a certain angle, which is convenient and flexible.
6. The three- and four-stage combination of this series of reducers provides a prerequisite for the generalization of slow cranes.
