(38) Hydraulic tank Two-Way / One Pump with electronic control is designed to allow complete electronic control over the work tool. This hydraulic system allows the operator to control a work tool with a two-way flow system with from one pump.Two-Way Flow from One Pump
Two-way flow from one pump can be achieved by selecting a work tool that requires two-way flow from one pump. The work tool can be selected through the monitor or by the work tool select switch. A typical example is a grapple that receives oil from one pump only.When one pump flow is required to
