動源制御装置。 A throttle lever for determining the throttle opening of an engine connected to a hydraulic pump for driving a concrete pump, a control lever for determining the maximum rotational speed of the engine, and a control lever for maximizing and controlling the throttle opening. The throttle lever can be switched between a manual state in which the maximum rotation speed can be controlled by manually operating the lever, and an automatic state in which the maximum rotation speed can be set to the maximum and the throttle opening degree can be controlled by an accelerator pedal connected to the throttle lever. A concrete pump drive source control device comprising an auto accelerator device connected to a lever and a control lever, and a control circuit for controlling the concrete pump and the auto accelerator device,
A control motor that can rotate in forward and reverse directions and whose rotation direction can be manually operated is connected to a control lever, and a control circuit keeps the control motor in a direction that minimizes the maximum rotation speed in response to turning off the concrete pump. A drive source control device for a concrete pump, characterized in that it is configured to operate only for a limited time.
