To reduce a cost by dispensing with a change of a control program for a controller when adding a corresponding function to a prescribed loading state to an existing loading platform lifting device.SOLUTION: A loading platform lifting device L comprises: a controller C which operates on the basis of a previously stored control program and performs switching control of communication switching means V1, V2 so as to move a loading platform 1 down when receiving a moving-down command to the loading platform 1; a pressure sensor PS which can detect that the hydraulic pressure of a hydraulic cylinder CL exceeds a prescribed limit pressure px in a prescribed loading state of the loading platform 1; and moving-down regulation means RE2 which can regulate moving-down of the loading platform 1 in the time of operation independently of the controller C. The moving-down regulation means RE2 is connected with the pressure sensor PS via the controller C such that the moving-down regulation means RE2 operates according to the detection of the pressure sensor PS in the moving-down process of the loading platform 1.SELECTED DRAWING: Figure 4

    【課題】所定積載状態への対応機能を既存の荷受台昇降装置に追加するに当たり、コントローラに対しては制御プログラムの変更を不要とし、コスト節減を図る。【解決手段】荷受台昇降装置Lは、予め記憶された制御プログラムに基づいて動作し、且つ荷受台1に対する下降指令を受けると荷受台1を下降させるよう連通切換手段V1,V2を切換制御するコントローラCと、荷受台1の所定積載状態で油圧シリンダCLの油圧が所定限界圧pxを超えていることを検知可能な圧力センサPSと、作動時には荷受台1の下降をコントローラCから独立して規制可能な下降規制手段RE2とを備え、荷受台1の下降過程で圧力センサPSの前記検知に応じて下降規制手段RE2が作動するように、その下降規制手段RE2と圧力センサPSとがコントローラCを介さずに接続される。【選択図】図4
