description The utility model discloses a heavy-load travelling crane auxiliary wheel mechanism with high stability, which relates to the technical field of heavy-load travelling crane auxiliary wheel devices and comprises a travelling crane cross beam, a connecting seat, a movable vertical rod, a connecting shaft, an auxiliary roller, a slide rail, a fixing component and a limiting component. Through the arrangement of the limiting assembly, the push rod moves to drive the moving block to move upwards, the moving block moves to drive the extrusion block to move through mechanical transmission, the first spring is stressed and extruded, the extrusion block moves to drive the two sliding blocks to move towards the two ends of the connecting shaft, and the sliding blocks move to drive the limiting column to move through mechanical transmission; and after a second spring is extruded by force, a limiting column moves into a sliding groove in a sliding rail and is fixed to a connecting base through a movable vertical rod, the
