BMH Type Semi Gantry Track Crane With Electric Hoist

The BMH type semi gantry track crane with electric hoist has a special structure and can be used in factory workshops and outdoor construction sites with special environments and special work requirements. BMH type semi-portal crane is a single-beam semi-portal crane with electric hoist as the lifting mechanism. It is a small and medium-sized crane with rail operation. The leg of the semi-portal crane has a height difference, which can be determined according to the civil engineering requirements of the use site. Its end beam at one end walks on the crane beam, while the end beam at the other end walks on the ground. Compared with the electric single-beam crane, it saves investment and space. Compared with the electric hoist gantry crane, it can save production space and indirectly save space cost in the long run. Therefore, it is often used in modern production.

The metal structure of the whole machine is composed of main beam, outrigger, upper crossbeam, lower crossbeam, connecting beam, ladder platform and other components. The upper crossbeam and lower crossbeam are mainly welded U-shaped beams made of steel plates. The correct installation of the vertical and horizontal deflection of the wheels and the crane running mechanism is guaranteed by the manufacturing and welding of the lower crossbeam. The outrigger is welded in the form of box structure. The stress is simple and clear, and the appearance is beautiful and generous. The outriggers, main beams and two main beams are connected with bolts to facilitate disassembly and assembly. The outriggers, upper beams, main beams and lower beams generally need to be pre-assembled in the manufacturer and marked to facilitate the smooth assembly on site and ensure the correctness and integrity of the final assembly of metal structures. The ladder and protective ring are welded with angle steel, round steel and flat steel. They are connected with the angle steel welded on the leg by bolts, which avoids on-site welding and is convenient for disassembly and assembly. According to the needs of the production environment, when the choice of ordinary electric single-beam crane or electric hoist gantry crane is not ideal, the semi-gantry crane is also a good solution.
