300 ton high speed railway Bridge Girder Erection Machine

Product Description

Beam Launcher for concrete bridge beam of bridge construction site 

Bridge Construction truss type beam launcher 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, is widely used in construction of Highway, bridges.

Beam Launcher Bridge girder erection machine merges an adaptation of a wide range of work, good compact structure, convenient operation, whole crane body with safety steel structure. This product can be used not only in plain construction environment, but also can meet the construction situation of mountain highway slope, Ramp bridge.

Beam launcher body includes main beam, cantilever, under guide beam, front and rear legs, auxiliary outrigger, hanging beam crane, cantilever structure and hydraulic driving system, with high performance and strong working efficiency.

This type launching crane is well applied in highway and bridge construction site and railway construction site. It can be used for environment of no fire, no explosion and no corrosive media with temperature from -20~55C.
