[0003] A modular gantry crane disclosed in the Chinese utility model patent application disclosure CN208361724U has the advantages of improving the overall stability of use and being safer when used as a whole, but the modular gantry crane still has disadvantages: First, the main beam and the supporting legs of the modular gantry crane are arranged as an integral whole. In actual use, the overall connection and combined use may be inconvenient for transportation and inconvenient for combined installation due to the large overall volume; Second, a hydraulic press is installed on the side beam of the modular gantry crane to adapt to the wheels at the bottom for movement and stabilization of the whole. However, in actual use, in order to support the entire crane, the size and power of the hydraulic press should be not small. It is not convenient for one person to operate when installed with bolts, and it requires the cooperation of two people to combine and install. Utility Model Content
