Advance DB55 Hydraulic Gearbox

The DB55 transmission is a fixed – shaft multi – speed power – shift transmission. With helical gear transmission and electro – hydraulic control, it features a separated installation of the dual – variable components, ensuring stable and efficient power transmission in various working conditions.
The engine’s maximum power reaches up to 58 kW, with a top speed of 2400 r / min and a maximum input torque of 670 N · m. This provides sufficient power support for construction machinery, enabling reliable operation under different loads.
Designed with a focus on durability and performance, the DB55’s helical gear transmission reduces noise and enhances gear – meshing efficiency. Its electro – hydraulic control system allows for smooth and precise gear shifting, improving overall operational convenience.
The separated installation of the dual – variable components simplifies maintenance and installation processes, making it easier to match and integrate with different engine models, which greatly enhances the product’s adaptability and application flexibility.
Widely used in ZL16 and ZL18 loaders, the DB55 transmission provides a reliable and efficient power transmission solution, contributing to the smooth operation of construction projects.
