The invention discloses a portable lifting trolley. A shear type hydraulic lifting mechanism comprises an outer shear fork, an inner shear fork, a driving oil cylinder for driving the outer shear forkand the inner shear fork to be opened and closed, and a lock assembly for locking the outer shear fork and the inner shear fork. A walking driving mechanism is arranged in the inner shear fork. Whenthe outer shear fork and the inner shear fork are in a folded state, the walking driving mechanism is located at a walking driving position capable of making contact with the ground. When the outer shear fork and the inner shear fork are opened, the walking driving mechanism is in a suspended state. The walking driving mechanism does not need an independent base. In the folded state, the walking driving mechanism is stored in the shear type hydraulic lifting mechanism, the height of one layer is not occupied independently, the overall height is small in the folded state, the size is small, andthe lifting trolley is suitable for working at the position with small space height, particularly suitable for entering the bottom of a to-be-maintained automobile to lift the automobile and accordingly matched with automobile maintenance.
本发明公开了一种随行移动的举升小车,剪式液压升降机构包括外侧剪叉、内侧剪叉、驱动外侧剪叉和内侧剪叉开合的驱动油缸和锁定外侧剪叉和内侧剪叉的锁组件,行走驱动机构设置在内侧剪叉内,当外侧剪叉和内侧剪叉处于叠合状态时,行走驱动机构处于能与地面接触的行走驱动位,当外侧剪叉和内侧剪叉打开时,行走驱动机构处于悬空状态。本发明行走驱动机构不需要独立的底座,在叠合状态时,行走驱动机构收到剪式液压升降机构之内,不单独占用一层高度,使得在叠合状态时整体高度较小,体积也较小,适于在空间高度较小的位置作业,特别适用于进入待维修的汽车底部将汽车举升,从而配合汽车维修。
