FRONT END LOADER WITH WATER INJECTOR

摘要

PURPOSE:To facilitate fitting/removal of the device by operating a water pump, arm device and water jet nozzle oil-hydraulically, and receiving the oil pressure for actuation with a hose of quick chuck type from a working machine hydraulic circuit of the body vehicle. CONSTITUTION:Pressure oil is divergently sent to a control valve unit 60 with a built-in arm device 28 through a hose of quick chuck type from a working machine hydraulic circuit from a working machine hydraulic pump 3 on the car body, and a command is given based on control operation by switch levers A-F on a control box 27 furnished in the cab via a control valve unit 60 equipped with a solenoid valve, and thus the pressure oil is fed to each cylinder and actuator to perform revolving, rise/fall and expansion/contraction of the arm device 28 as well as rotation of the water jet nozzle 24. Use of this hose of quick chuck type ensures that the working machine hydraulic circuit on the car body can oil-hydraulically be connected and separated with/from the arm device 28 freely as desired.
