Overhead bridge crane metal structure from the main beam and side beams, divided into single girder bridge and two double-girder bridge. Single girder bridge by a single span girders and located on either side of the end beam composed by two double-girder bridge girders and end beam components. Main beam and side beams rigidly connected at both ends of the end beam which wheels to run on an elevated bridge support. The main beam welded track for lifting the car running. The main beam of the bridge structure type more typical box-shaped structure, four truss structure and fasting truss structure. Box-shaped structure can be divided into two-track box girder, double girder off-track box, off-track box single girder several. Double track box girder is a widely used basic form, the main beam from the vertical web of upper and lower flange plates and sides of the composition, the car rails disposed on the flange plate on the center line, simple structure, Manufacturing convenient, suitable for mass production, but larger self. Partial rail box girder and double Partial rail box-section main beams are made of a single upper and lower flange plates and ranging in thickness consisting of primary and secondary webs, trolley rails disposed above the main web, cabinets of short stiffening board may be omitted, in which off-track box by a single girder box girder flange width instead of two main beam, the smaller the weight, but the manufacturing is more complex. Common bridge crane mainly electric drive, usually operated in the cab, there are remote controlled overhead crane. From the weight of up to 500 tons, span up to 60 meters. Lifting Equipment Co., Ltd. Shandong Lu Xin first five mountains located at the foot of Mount Tai - Xintai City sheep flow zone, the company crane production base in Shandong Province as the basis, set Delirenhuo in one, with a scientific management system, convenient transportation conditions, strong production capacity and advanced detection instruments, strong sales network and rely on local technology. Talent.
