Wheel Loaders

On the wheel loader, which is operated with carrying broken stones or timber, KLW series or KML series control valves designed specially for this application are utilized as well as high efficiency and low noise Hydraulic Pumps such as K3VLS series. For the machines which employs the Hydrostatic Transmission system K8V series pumps and M7V series motors realizes highly efficient system as well as superior driving confort.
