Fuel-efficient Doosan DL420CVT-5-wheel loader

16 February, 2018

The CVT design combines the benefits of a mechanical transmission and a hydrostatic transmission in the same machine. It allows the DL420CVT-5 to automatically transition from hydrostatic power at low speed to the mechanical system to operate at higher speeds.

By combining the two types of transmission, the new CVT technology ensures high loads can be carried at low engine speeds with high dynamics for an optimum wheel loader operating cycle. The DL420CVT-5 therefore provides an increase in machine performance for operators working in digging, loading and lifting applications.

Up to 15% additional fuel savings

The complete driving range, forwards and in reverse, is controlled by the CVT system. Low engine speeds ensure a high efficiency and the highest driving comfort irrespective of the traction speed. The power splitting continuously variable technology facilitates moving off softly and hydraulically. Furthermore, with the CVT, a fuel saving of up to 15% is said to be achievable.

Load-sensing hydraulic pumps

All new generation Doosan wheel loaders have a load sensing hydraulic pumping system, whereby the variable axial piston pump generates the flow upon demand in the amount necessary to perform the work.
