Abstract

The invention discloses a dual-beam trussed gantry crane. The gantry crane comprises bases, wherein moving wheels are arranged in the bottoms of the bases; supporting columns are fixed at the top endsof installation pieces; connecting blocks are welded and fixed at the top ends of the supporting columns; stabilizing blocks are connected to tops of flanges, limit rods are connected to top ends ofthe stabilizing blocks, and connecting pieces are fixed on the inner sides of the stabilizing blocks; a dual-beam body is installed at the top ends of fixing blocks; chutes are fixed in the dual-beambody, and pulleys are connected inside the chutes; a dustproof plate is connected to the outer side of the middle of a winding box; buffer structures are arranged on the left and right sides of the winding box, and a winding structure is arranged above the winding box. The dual-beam trussed gantry crane is convenient to install, and can effectively manage lines; besides, the impact force of the winding box on the dual-beam body can be effectively reduced, and the winding box moves left and right smoothly.

Description

technical field [0001] The invention relates to the related technical field of a double main girder trellis gantry crane, in particular to a double main girder trellis gantry crane. Background technique [0002] As the demand for drilling platforms increases, large cranes are required to be used in the overall production of offshore drilling platforms. It is necessary to lift and assemble large sections of drilling platforms, and to adapt to different tower heights and different widths of drilling platforms. Many high-altitude operations are changed to level ground operations and installed at one time, which not only saves the man-hours of drilling platform manufacturing, shortens the construction period, but also ensures the safety of personnel and improves product quality; [0003] For example, a crane with double main girders and multiple lifting points, whose authorized announcement number is CN101104501B, can realize super-large load lifting; the double main girder stru...
