QYD30L Forklift Transmission

Main Characteristics
  • QYD30L consists of a hydraulic torque converter and a transmission with one front shift and one reverse shift. It is used for forklift ,tractor and other construction machinery.
  • Using two stage reduction and differential semi-shaft as output, the transmission output is connected with the reducer input by universal coupling. The shift mode is electromagnetic controlled power shift with inching valve and buffer valve, which makes the operation simple, convenient, stable to start and greatly reduces the labor intensity of the operator.
