To provide a vehicle maintenance lift device by which a plurality of lifts can be lifted or lowered to be accurately interlocked with one another.SOLUTION: Each of first to fourth lifts 10 to 13 includes: a wire encoder 51 for detecting a lift height which is a lifting/lowering height of a ram 22c; a support state detection part 6123 detecting whether a vehicle is in a support state in which it is supported by a receiving base 30 or a non-support state in which it is not supported thereby; and a reference height storage part 613a storing a lift height HE detected by the wire encoder 51 as a reference height H0 of each of the first to fourth lifts 10 to 13 when the support state is detected by the support state detection part 6123. A vehicle maintenance lift device 1 includes an interlocking control part 6127 for lifting/lowering the first to fourth lifts 10 to 13 to be interlocked with one another while maintaining a vehicle in an approximately horizontal posture based on the movement amount of each lift with reference to each reference height H0 of the first to fourth lifts 10 to 13.SELECTED DRAWING: Figure 1
【課題】複数のリフトが正確に連動して昇降動作することができる車両整備用リフト装置を提供する。【解決手段】第1~第4リフト10~13はそれぞれ、ラム22cの昇降高さであるリフト高さを検知するワイヤエンコーダ51と、車両が受台30によって支持されている支持状態か支持されていない非支持状態かを検知する支持状態検知部6123と、支持状態検知部6123によって支持状態が検知されたとき、ワイヤエンコーダ51によって検知されたリフト高さHEを第1~第4リフト10~13の基準高さH0として記憶する基準高さ記憶部613aとを備える。車両整備用リフト装置1は、第1~第4リフト10~13の各基準高さH0を基準とする各リフトの移動量に基づいて、車両を略水平姿勢に保持した状態で、第1~第4リフト10~13を連動して昇降動作させる連動制御部6127を備える。【選択図】図1
