HSE Slewing Drive Gearbox

LDB’s single-cylinder rotary reducer for heavy vehicles was originally a customized model for hydraulic modular vehicles. Due to the special design of the slewing bearing structure, it may bear relatively large axial dynamic loads. At the same time, the large-modulus structure design can meet the requirements of modular vehicles. (Vehicles have high requirements for output torque) At present, it occupies more than 80% of the domestic market and has been recognized by customers.
