This gearbox is designed for the heavy duty overhead crane and gantry crane with capacity 200-500t. It adopts hard-toothed gear transmission technology with the features of large carrying capacity, high transmission precision, convenient installation, long service life and simple maintenance, and the structure adopts double-input and double-outlet form, and the middle connection is by the meshing wheel to realize synchronization at both ends. This gearbox greatly enhances the mechanical transmission accuracy, reduces the probability of parts failure, and improves the crane operating efficiency. 

Structural Features:

1. Rectangle box layout, suitable for multi-lifting-point crane structure;

2. Precision synchronous output at both ends, synchronous lifting;

3. Independent lubrication and cooling system, suitable for various working conditions;

4. Equipped with ratchet pawl mechanism, anti-reverse and safe;

5. Hard-toothed gear transmission technology.
