Claims

[Scope of utility model registration request]

A hydraulic pump driven by an engine, a hydraulic actuator that operates by receiving pressure oil from the hydraulic pump, and a directional switching valve that controls supply of pressure oil to the hydraulic actuator, and the directional switching valve In a hydraulically driven working machine in which switching can be performed by operating a control lever, a cam is provided between the control lever and the directional control valve and rotates in conjunction with the control lever to switch the directional control valve. , and the cam has two operating positions: a first operating lever position until switching of the directional switching valve is completed, and a position where the lever is further operated from the first operating lever position, and the directional switching valve is closed. A cam surface for controlling the directional switching valve is provided so that the switching remains at a second operating lever position, and an accelerator interlocking part that enables engine output adjustment is operated from a predetermined position of the operating lever. A control device for a hydraulically driven working machine, characterized in that it is configured to be linked to a lever.
