Advance BS428 Hydraulic Gearbox

The BS428 transmission is a fixed – shaft multi – speed wet clutch transmission. With a separated installation of the dual – variable components and electro – hydraulic control for gear shifting, along with high – low gear shifting via a parking fork mechanism, it offers stable and reliable performance under diverse working conditions.
The engine’s maximum power reaches up to 74 kW, with a top speed of 2500 r / min and a maximum input torque of 650 N · m. This ensures robust power support, enabling the construction machinery to operate steadily even under heavy loads.
Featuring a wet clutch design, the BS428 transmission provides enhanced heat dissipation and wear resistance, prolonging the service life of the components. The electro – hydraulic control system enables smooth and accurate gear changes, while the high – low gear parking fork shifting mechanism offers flexible operation options.
The separated installation of the dual – variable components simplifies the maintenance and installation process, facilitating better compatibility with various engine models and enhancing the product’s versatility and application scope.
Widely used in ZL20 and ZL30 loaders, the BS428 transmission offers an efficient and dependable power transmission solution, contributing to the efficient execution of construction projects.
