Beam fabricating gantry crane is a general type of gantry crane which is widely used in bride engineering of passenger high-speed railway.This trpe of crane could be used to lift and move beams in the processes of lowering beams down from production platform and of moving them up on to flat beams car conveniently.lt could also lift beams onto bridge piers directly when its legs are lengthened.There are several models such as 450t. 225t types and so on. 2 sets of crane are combined to move beams to move or to lift for beams installation.
This type of gantry crane is composed by load bearing steel structure ,lift trolley,crane travel mechanism and electrical control system.The steel structure was welded by high strength low alloy steel.Lifting mechanism was composed by winding system through ratio pulley.The triad driven crane travel mechanism was composed by inverter motor and cycloidal pin-wheel reducer. The electric system control is through PLC.This type of crane has beautiful outlook,each component was independent that can be easily and quickly assembled and disassembled.
