The main function of the fixed legs is to support after being assembled with movable legs and cooperating with the oil cylinder to expand and contract, reduce the load on load-bearing components such as axles and tires of the vehicle, ensure the stability of the whole vehicle, and avoid tipping over when lifting goods. With the improvement of the large-tonnage folding boom truck crane model spectrum, the pitch dimensions of the fixed legs are increasing. For one type of crane, there are two widths and heights, and different toolings are matched according to the size specifications, resulting in a large cost and occupying a large production space.

[0003] At present, the fixed leg structure with a door panel is composed of two groups of side plates, one group of bottom and cover plates, and a door panel assembly. The traditional spot welding method uses a square to measure perpendicularity, a square to measure width, height and diagonal to ensure the pitch and geometric dimension requirements; some manufacturers use the method of internal partitions to ensure the pitch and geometric dimension requirements; currently, medium and large enterprises use automation and a servo motor linkage control adjustment dimension device. The traditional production method cannot guarantee production quality under the premise of ensuring efficiency, cannot meet the pitch and geometric dimension requirements of workpieces, increases the difficulty of subsequent work, and requires a high skill level of operators. However, the automated production equipment has high upfront investment and high maintenance and repair costs, and cannot meet the needs of small and medium-sized enterprises.
