Gantry crane bridge structure design description

  With the development of modern industry, cranes in metallurgy, machinery, transportation, electricity, construction, mining, chemicals, shipbuilding, ports and defense industrial sectors more widely. It is for the development of national economy and improving people's things, cultural life plays an important role. With the rapid development of economic construction, mechanization, the degree of their own initiative are constantly improving, and this is also the skills to adapt to the rapid development of the crane, a steady increase in the product category, electric hoist  overhead gantry crane  scale used more widely.
       Some companies because there is no lifting, working not only inefficient, labor-intensive, and even harder work. High-rise building construction, on or tens of tons tons of large-scale boat building, rocket and missile launch, construction and installation of large power stations, large loading and unloading and transport of heavy pieces, etc., are inseparable from the crane operation . Electric  hoist gantry crane  in the production process not only play a supporting role, but the mass production and assembly line has become an indispensable part of it is the mechanization and automation, improve labor productivity, reduce manual an important tool.
        Electric hoist gantry crane bridge is formed by a steel structure, the structure in the form of truss constructions. To do the main beam I-beam, main beam welded at both ends of the side beams constituting channel; in the main beam is placed on one side of the horizontal angle constituted and vertical truss truss, used to install the drive mechanism and enhanced bridge carts horizontal stiffness. When the span of ≥ 9.5 meters, at the top of the main beam welded channel on the composition of the cantilever, in order to ensure the strength and stiffness of the bridge, as well as reduce the structural weight.
       Electric hoist  bridge gantry crane  traveling mechanism is divided into two kinds of centralized transmission and separately driven, the main driven wheel angular bearing housing is bolted to the end beam ends. Motor, reducer and brake are centrally installed in the walk on stage. The coupling wheel by the brake motor and reducer input shaft coupling, during a solenoid brake reducer output shaft via a gear coupling, shaft, bearing frame is connected with the driving wheel, when the motor starts, both drive Active Wheel running.
