To provide a loading platform lifting device which can always turn a loading platform into a substantially-horizontal attitude during either moving-up or moving-down by skillfully controlling the downward rotation and the upward rotation with respect to the tip of a loading platform to be grounded.SOLUTION: A loading platform lifting device includes: a lift arm which can be rotated vertically with respect to a vehicle; a loading platform which is coupled in a vertically-rotatable manner to the tip of the lift arm; a lift cylinder which moves the loading platform up/down in the substantially-horizontal attitude by vertically rotating the lift arm and further rotates the tip of the loading platform grounded in the substantially-horizontal attitude downward; a tilt cylinder which vertically rotates the loading platform with respect to the lift arm; an inclination sensor which can detect the inclination attitude of the loading platform; and a control unit which controls the inclination angle of the loading platform on the basis of the detection of the inclination sensor. The upward rotation of the loading platform controls the expansion/contraction of both cylinders.SELECTED DRAWING: Figure 2

    【課題】接地する荷受台の先端に対する下方回動および上方回動を巧みに制御することで、常に上昇および下降のいずれの作動時には略水平姿勢とすることが可能な荷受台昇降装置を提供する。【解決手段】車両に対して上下に回動可能なリフトアームと、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、リフトアームを上下に回動させて荷受台を略水平姿勢で昇降させるとともに略水平姿勢で接地した荷受台の先端部をさらに下方回動させるリフトシリンダと、リフトアームに対して荷受台を上下に回動させるチルトシリンダと、荷受台の傾斜姿勢を検知可能な傾斜センサと、傾斜センサの検知に基づいて荷受台の傾斜角度を制御する制御部とを備え、荷受台の上方回動において、両シリンダの伸縮が制御される。【選択図】図2
