Doosan's DL420-5 CVT is a 311-hp Loader with Continuously Variable Transmission

The DL420-5 CVT (continuously variable transmission) is the first Doosan wheel loader that combines the benefits of a traditional automatic transmission and a hydrostatic transmission in one machine. The CVT automatically transitions from its hydrostatic driveline to the automatic-transmission side to operate at higher speeds. For most tasks, operators will utilize the hydrostatic part of the transmission, which is more efficient than an automatic transmission in low-speed applications. The hydrostatic part of the transmission provides good overall performance at lower engine rpms. Unlike torque converter transmissions, the DL420-5 CVT wheel loader’s automatic transmission is a one-to-one ratio with the engine. The automatic driveline improves powertrain efficiency in load-and-carry operations.
