The invention provides a pneumatic hydraulic lifting trailer. The pneumatic hydraulic lifting trailer comprises a frame for carrying, connecting frames symmetrically hinged to the two sides of the frame, idler wheels hinged to the connecting frames, pneumatic lifting devices for driving the frame to ascend and descend, and dampers playing a role in buffering and damping. The pneumatic hydraulic lifting trailer has the advantages of being simple in structure and convenient to operate, the frame on the pneumatic hydraulic lifting trailer is controlled to ascend and descend through the pneumaticlifting devices arranged on the pneumatic hydraulic lifting trailer, when the frame descends to be flush with the ground, a vehicle can be directly driven to the frame, transportation of the vehicle is facilitated, and the transfer process of the vehicle is simple; and the dampers and the pneumatic lifting devices on the hydraulic lifting trailer act together to play a role in shock absorption.

    本发明提出了一种气动液压升降拖车,用于运载的车架、对称且铰接设置在所述车架两侧的连接架、铰接设置在连接架上的滚轮、驱动车架升降的气动升降装置,以及起到缓冲减震作用的阻尼器。本发明所提供的一种气动液压升降拖车,具有结构简单、操作方便的特点,其上的车架通过设置在其上的气动升降装置来控制升降,当车架降低至于地面平齐时,可直接将车辆驾驶至车架上,便于对车辆的运输,对车辆的转运过程简单,且其上阻尼器与气动升降装置共同作用,起到减震的作用。
