ABSTRACT:
A moving speed regulator for a hydraulically driven work implement capable of automatically controlling the lifting speed of a boom, and regulating the maximum lifting speed thereof in particular during earth and sand scooping operation, and also having for its object to enable the lifting speed of the boom when the boom is lifted to a position near its highest position. This regulator comprises a pilot circuit (10) having a pilot pump (P); a hydraulic circuit for driving a work implement, which includes a work implement operating valve (g) adapted to be actuated by a pilot fluid pressure from a hydraulic pilot valve (i.sub.1) installed in the pilot circuit; a pressure regulating valve (12) installed in said pilot circuit; and a change-over valve (11) for changing over the pressure regulating valve either to its operative condition or to its inoperative condition, and wherein the maximum discharge flow rate of the fluid through the work implement operating valve can be controlled by regulating the pressure of the fluid under pressure through the cooperative effect of the change-over valve and the pressure regulating valve.
