とする穴掘建柱車の安全装置。 An auger drill that can be rotated is suspended from the tip of a telescoping boom that is mounted on a vehicle so that it can be raised and lowered by a hydraulic cylinder for raising and lowering, and the telescopic boom is driven to lower and press the auger drill to the ground. This is a safety device for a drilling pole construction vehicle configured to drill a hole in the ground by rotationally driving an auger drill. A dowel lifting force detector configured to detect the hoisting force that pushes up the telescopic boom generated by the propulsive force of the auger drill itself when rotating by detecting the load acting on the hoisting drive hydraulic cylinder. , a boom length detector for detecting a telescoping boom length of the telescoping boom, a limit value output means for receiving a boom length signal from the boom length detector and outputting a limit value as a function of the boom length of the telescoping boom, this limit value. a comparison means that receives a limit value signal from the output means and a signal from the auger force detector and outputs an auger drill rotation drive regulation signal when the latter signal is lower than the former signal; and an auger drill rotation drive from the comparison means. A safety device for a hole-drilling pole-erecting vehicle, characterized in that it comprises an alarm means activated by a regulation signal or an auger drill rotation drive limiting means.
