 railway/highway/bridge construction truss type beam launcher bridge erection machines

Bridge launching is a professional construction machinery, which is used to transfer the road concrete precast blocks and bridge beams to the position of abutments or supporters, and then built road or highway bridge.

The launching crane composed of horizontal moving girder devices, main girders, support system, vertical moving gantry devices, horizontal moving gantry devices, hydraulic system and electrical control system.

Highway bridge is the highway bridge prestressed concrete beam tablet or beam section lifting to bridge bearing on the special construction machinery. Mainly by the beam longitudinal shift flat car assembly, girder components, support system, the longitudinal shift system, the transverse system, hydraulic system, electric control system components.

Main girder is commonly double beam truss structure. At present domestic highway bridge structure form in roughly the same, the main difference is that the longitudinal guide beam bridge form and via way. According to the longitudinal guide beam forms can be divided into single guide beam bridge and double guide beam bridge, according to the via form is divided into LunGuiShi bridge and walking machine.
