    • PROBLEM TO BE SOLVED: To provide a dump trunk that can be precisely guided to a destination even while unmanned without modifications being made to safety-critical parts.SOLUTION: A dump trunk includes a manned steering valve 20 for controlling the supply of oil to a steering cylinder SC in response to operation of a handle 21, an unmanned steering valve 30 for controlling the supply of oil to the steering cylinder SC in response to a control signal provided from a controller 40, and a main switching valve 70 which is provided on manned oil supply paths 23L and 23R at a location thereon upstream from the points of connection to unmanned oil supply paths 31L and 31R, the main switching valve 70 being used for switching the manned steering valve 20 and the steering cylinder SC between a communication state and a cutoff state. When oil is to be supplied to the steering cylinder SC via the unmanned steering valve 30, the main switching valve 70 provides a cutoff state between the manned steering valve 20 and the steering cylinder SC.
    • 要解决的问题:提供一种可以精确引导到目的地的倾倒式干线,即使在无人作战时也不会对安全关键部件进行修改。解决方案:倾卸式干线包括一个人力转向阀20,用于控制向 转向缸SC响应于手柄21的操作,用于根据从控制器40提供的控制信号控制向转向缸SC供油的无人驾驶转向阀30和设置在控制器40上的主切换阀70 载人油供给路径23L,23R位于与无人供油路径31L,31R的连接点上游的位置上,主切换阀70用于在人工转向阀20和转向缸SC之间切换通信状态和 一个截止状态。 当通过无人驾驶转向阀30向转向油缸SC供油时,主切换阀70在人工转向阀20和转向油缸SC之间提供切断状态。

    • PROBLEM TO BE SOLVED: To provide a bending construction vehicle that is suitable for traveling on a normal roadway and steered in a manner suitable also for work on a construction site.
      SOLUTION: The bending construction vehicle has a bendable self-propelled vehicle body 1, a vehicle-body bending hydraulic cylinder 2 for bending the self-propelled vehicle body, a pilot-operated direction switching valve 5 that controls the flow of pressurized oil to the vehicle-body bending hydraulic cylinder 2, an operation device 6 for a steering wheel that outputs a pilot signal to a signal receiving part of a direction switching valve 7 by rotation operation of a steering wheel 7A so as to change over the switching valve 5, an operation device 10 for an electric lever that outputs an electric signal by tilting-operation of a lever 11A, a controller 11 that is inputted with the electric signal of the operation device 10 so as to output an electric signal related to operation of the lever 11A, a signal conversion means that converts the electric signal into a pilot signal and outputs it to a signal receiving part of the direction switching valve 5 so as to change over the switching valve 5, and a selection means that has an operation system for allowing the operation of the direction switching valve 5 by rotation operation of the steering wheel 7A or by tilting-operation of the lever 11A to be selectively performed.
