QY Series Crane Gear Reducers
QY Series Crane Gear Reducers
FEATURES:
1. High bearing capacity, gear is carburized, Quenched and grinded.
2. Small size and light weight
3. High efficiency, low noise and low vibration
4. The multi-stage number is adopted to reduce the single-stage speed ratio, the center distance can be opened and the whole height of reducer can be reduced to meet the requirements of various mechanisms of crane
5. The three fulcrum reducer can be installed vertically, horizontally or even deflected to a certain angle, which is convenient and flexible.
6. The combination of three and four stages (i.e. three-stage assembly type and four-stage transmission ratio) provides the premise for the generalization of slow crane.
DESCRIPTION
QY reducer includes QYS (three fulcrum) and QYD (base type) hard tooth surface reducer for crane. It has three types: three pole, four stage and three four level combination type
