PROBLEM TO BE SOLVED: To provide a braking safety system in which useless installation of a brake can be eliminated in the case that a service car is stopped on an inclined road surface.SOLUTION: A braking safety device 100 comprises: brake detectors 111 to 114 which are provided in the front and rear of left and right wheels of a vehicle for high lift work and detect brakes; an inclinometer 102 for performing detection for determination of a front lower inclination or a rear lower inclination of a road surface on the basis of the front and rear of the vehicle for high lift work; a controller 101 which determines the front lower inclination or the rear lower inclination of the road surface with use of a detection value detected by the inclinometer 102, and outputs an alarm signal when the brake detectors 111 to 114 do not detect brakes installed on a slope foot side of the left and right wheels; and jack-up lamps 131a to 131d which notifies that brakes 20 are not installed on the basis of the alarm signal outputted from the controller 101.SELECTED DRAWING: Figure 3
【課題】作業車が傾斜した路面に停車する場合に歯止めの無駄な設置をなくすことができる歯止め安全装置を提供する。【解決手段】歯止め安全装置100は、高所作業車の左右の車輪の前後に設けられ、歯止めを検出する歯止め検出部111〜114と、高所作業車の前後を基準にした路面の前下がり傾斜または後下がり傾斜を判断するための検出を行う傾斜計102と、傾斜計102により検出された検出値を用いて路面の前下がり傾斜または後下がり傾斜を判断し、歯止め検出部111〜114が左右の車輪の坂下側に設置される歯止めを検出しないときに警告信号を出力する制御部101と、制御部101から出力された警告信号に基づいて歯止め20が設置されていないことを報知するジャッキアップランプ131a〜131dとを備えている。【選択図】図3
