PROBLEM TO BE SOLVED: To provide a mobile lifting platform device which may move up or down support legs in response to upward or downward movement of a scissors link mechanism.SOLUTION: A lifting platform device includes: a dolly part 2; a lifting drive device disposed at the inner side of the dolly part 2; a scissors link mechanism disposed above the dolly part 2; and a work table supported by the scissors link mechanism. The dolly part 2 includes: a substantially rectangle frame body 6; support legs 7 erected to the lower side at four corners of the frame body 6; lift arms 10, each of which is connected to the frame body 6 through an attachment shaft 27 and moves up and down the support leg 7; wheels 8 which enables the lifting platform device 1 to travel; and connection rods 9, each of which connects the left and right wheels 8. The scissors link mechanism includes pressing parts which respectively press the lift arms 10 to the lower side. Each lift arm 10 includes: a second resin roller 33 which is attached to the lift arm 10 through a receiving part shaft 34 so as to face and contact with a lower end of the pressing part; and a first resin roller 29 which is attached to the lift arm 10 through a fulcrum shaft 32 so as to contact with the connection rod 9.

    【課題】シザースリンク機構の昇降に対応して支持脚を昇降可能な移動式の昇降台装置を提供する。【解決手段】台車部2と、台車部2の内側に配設された昇降駆動装置と、台車部2の上方に配設されたシザースリンク機構と、シザースリンク機構によって支持された作業台と、を備えた昇降台装置であって、台車部2は、略矩形状の枠体6と、枠体6の四隅に下方に立設した支持脚7と、枠体6に取付軸27を介して連結され、支持脚7を昇降させるリフトアーム10と、昇降台装置1を走行可能とする車輪8と、左右の車輪8を連結する連結杆9と、を備え、シザースリンク機構は、リフトアーム10を下方に押圧する押圧部を備え、リフトアーム10は、押圧部の下端に対向して接触するように受部軸34を介して取り付けた第2樹脂ローラ33と、連結杆9に接触するように支点軸32を介して取り付けた第1樹脂ローラ29と、を備える。【選択図】図5
