[0003] The movable hydraulic platform is one of the most common hydraulic platforms. Compared with the fixed hydraulic platform, the movable hydraulic platform is more convenient to move. However, due to the heavy weight of the movable hydraulic platform, it is not convenient to lift it off the ground, and it is not convenient to transport or lift it over a long distance. Therefore, during the transportation or lifting process of the movable hydraulic platform, it is usually used together with a lifting auxiliary component. The existing lifting auxiliary component is generally a lifting structure, which drives the lifting arm to rise and fall by hydraulic or electric, so as to assist the hydraulic platform to lift off the ground through its lifting arm;

[0004] However, it still has the following disadvantages in actual use:

[0005] The existing lift-off auxiliary components can only be used on movable hydraulic platforms of the same size, and the sizes of movable hydraulic platforms are diverse, so their applicability is relatively small;
