Abstract
PURPOSE:To easily perform the operation of a separate hydraulic actuator and the automatic rolling control of working part by the operation of only one manual operation tool, by interlocking a manual operation tool with an objective selector valve and a control valve in a specific state. CONSTITUTION:A cylinder-operation switch 20 interlocked with each of selector valves 17, 18 and a control valve 10 is provided by interlocking the tool with an operation circuit 19 for the 1st and 2nd selector valves 17, 18 to be operated and an operation circuit 11 for the control valve. A series of operation of the titled lever part 20a enables and alternative selection between two states i.e. an automatic control state wherein the hydraulic actuator 6 for rolling is connected with the control valve 10 and the control value is operated by a rolling controlling mechanism 9 and a manually controlled state wherein another hydraulic actuator 14 is connected with the control valve and the control valve takes a driving position preferentially to the rolling controlling mechanism.
