PROBLEM TO BE SOLVED: To input power supply to an upper controller from the lower part of a vehicle without an operator riding on a workbench. SOLUTION: A remote control type power supply control device 19 comprises a control part 21 and an operating part 23. The operating part 23 is provided with a battery 27, a leveling device 33 operated when supplied with the power of the battery 27, and a pressure switch 39 for making or breaking an electric connection between the battery 27 and the leveling device 33. The pressure switch 39 is of the hydraulic actuated type that is actuated in response to a hydraulic force, and the control part 21 is a hydraulic pressure generating switch 25 for generating a hydraulic force when operated. The hydraulic pressure generating switch 25 and the pressure switch 39 are communicated to each other by an oil passage 51 made of an insulating material. When the hydraulic pressure generating switch 25 is pressed, the pressure switch 39 is operated accordingly by the hydraulic force via the oil passage 51 to establish an electric connection between the battery 27 and the leveling device 33 to supply the power of the battery 27 to the leveling device 33.
