This utility model discloses a movable base for a lifting platform, relating to the field of lifting platform mobility technology. It includes a base with a support frame movably connected to one side, a tire fixedly connected to the bottom of the base, and a support assembly at the bottom of the base. The support frame includes a connecting block, one side of which is fixed to one side of the base. Upon activation of the support frame, the support frame drives a transmission rod to move within the connecting block, thereby causing a limiter and a fixed column to move synchronously. At this time, the adjusting screw rotates, and using a threaded structure, the fixed column drives the adjusting column to move up and down along its inner wall. The adjusting column then drives the support base plate to move downwards, causing the support base plate to tightly press against the ground and achieve stable fixation. This process, through mechanical linkage and threaded adjustment, precisely controls the position and pressure of the support base plate, providing reliable support for the overall equipment, effectively enhancing equipment stability, reducing the risk of shaking and displacement, and ensuring normal equipment operation.
