備えたことを特徴とする作業車の安全装置。 In a working vehicle that is equipped with a main braking device that brakes the wheels, and is equipped with an outrigger and a working device that are operated by a driving motor on the vehicle body, the main braking device and a part of its piping are shared, and the braking force generated by hydraulic pressure is a working auxiliary braking device that fixes the pressure to keep the working vehicle in a stopped state; a first detector that detects the operation of the working auxiliary braking device; and a PT.
a second detector for detecting connection/disconnection of O; a tilt angle detector for detecting the tilt angle of the vehicle body; The present invention is characterized by being equipped with an operation stop device that operates on a slope when the work auxiliary braking device is not operating and the PTO is connected, and disables the outrigger grounding operation and the operation of the work equipment. Safety equipment for work vehicles.
