防止装置。 A fuselage frame 4 provided with a left and right traveling device 1, and an elevating cylinder 1 that drives the left and right traveling device 1 up and down.
9, a control means is connected to an operating device for lifting and lowering the tilting operation, a tilt sensor 71 for detecting the amount of horizontal tilt of the aircraft, and a solenoid valve 61 for adjusting the pressure of the lifting cylinder 19. The tilting operation by the operating device is performed via the control means, and when the tilt angle approaches the overturning angle, the control means causes the lifting cylinder 19 to stop operating in the overturning direction, giving priority to the tilting operation in the overturning direction. Fall prevention device.
