To detect change in electrical response of an inclination sensor due to flooding or disconnection of an electrical wire.SOLUTION: In a burden receiving table hoist unit which comprises a lift arm which is capable of vertically turning to a stem structure to be attached to a vehicle, a burden receiving table which is connected to a tip end of the lift arm in a manner capable of vertically turning, a lift cylinder which vertically turns the lift arm, a tilt cylinder which vertically turns the burden receiving table to the lift arm, an inclination sensor which measures inclination of the burden receiving table on the basis of a gravity direction, a control device which controls the tilt cylinder on the basis of signals of the inclination sensor and an electrical wire which connects the control device with the inclination sensor, the control device stores reference data for determining abnormality about the signal of the inclination sensor and determines presence or absence about abnormality of the electrical response of the inclination sensor by comparing the signal of the inclination sensor with the reference data.SELECTED DRAWING: Figure 14
【課題】電気配線の浸水又は断線による傾斜センサの電気応答の変化を検知する。【解決手段】車両に取り付ける基部構造体に対して上下に回動可能なリフトアームと、前記リフトアームの先端に上下に回動可能に連結した荷受台と、前記リフトアームを上下に回動させるリフトシリンダと、前記リフトアームに対して前記荷受台を上下に回動させるチルトシリンダと、重力方向を基準に前記荷受台の傾斜を測定する傾斜センサと、前記傾斜センサの信号を基に前記チルトシリンダを制御する制御装置と、前記傾斜センサと前記制御装置とを接続する電気配線とを備えた荷受台昇降装置において、前記制御装置は、前記傾斜センサの信号について異常判定するためのリファレンスデータを記憶しており、前記傾斜センサの信号を前記リファレンスデータと比較して前記傾斜センサの電気応答の異常の有無を判定する。【選択図】図14
