Abstract
PURPOSE: To safely operate a truck crane during truck running, by controlling the operation of a change-over cylinder for changing a high and low speed governer over to an overall speed governor for the crane truck, through a switch or the like which detects the nonrunning state of the crane.
CONSTITUTION: In operating a crane in running, a second switch 21 is connected to a side (a), a changeover solenoid valve 22 is opened and the pressurized fluid of a fluid source 13 is supplied into the expansion side chamber 23' of a cylinder 23 to connect a PTO unit to enable crane work. At that time, a first switch 25 is open because of the running. For this reason, another change-over solenoid valve 12 not actuated and the pressurized fluid of the fluid source 13 is supplied into a change- over cylinder 15. As a result, a governor acts as a high and low speed governor and an operator on a driver's seat can control the output of an engine by regulating the depression of a pedal 1.
