Double main girder structure structure 1. Use joist or beam welded angle, the advantage of low cost, light weight, wind resistance. However, due to the welding points and truss own shortcomings, joist also has a large deflection, stiffness Changsha small gantry crane, reliability is relatively low, the need for frequent detection of weld defects. Applies to lower security requirements, from the weight of the smaller venues. 2. box beam using steel plate welded into the box structure of Guangzhou gantry crane, high security, rigidity and other characteristics. Generally used for large tonnage and large tonnage gantry crane. As the right MGhz1200, from the weight of 1,200 tons, for the largest gantry crane, the main beam with a box girder structure. Girder also has high cost, self-important, less wind resistance and other shortcomings. 3. Cellular beams are generally referred to as "cellular beams isosceles triangle", the main beam end face is triangular, honeycomb holes on both sides of the oblique abdominal, upper and lower chords there. Cellular and joist girder box beam absorption characteristics than the joist with greater rigidity, small deflection, and higher reliability. However, due to the use of welded steel, self-respect, and the cost is slightly higher than the joist. Applicable to the use of frequent or large venue or lifting beam field. Because of this beam type is patented products, so manufacturers produce less. Guangzhou gantry crane | gravity lifting (certified) | Gantry Crane Co. gravity provided by Henan Province.
