とする建設機械の給脂ポンプシステム。 Hydraulic actuators are actuated by pressure oil discharged from one or more hydraulic pumps, and directional control valves of these hydraulic actuators are switched and controlled by pilot pressure from a pilot pump provided separately from the hydraulic pump. In a construction machine equipped with a hydraulic drive system as described above, a branch pipe is connected to the discharge pipe of the pilot pump, and a grease pump is connected to the branch pipe via a stop valve to control the discharge pressure of the pilot pump. A greasing pump system for construction machinery, characterized in that it is rotatably driven by oil and centrally supplies greasing points to greasing points using a grease gun and pre-arranged conduits.
