Beam Launcher Crane Information
China concrete railway road bridge construction Beam Launcher machine is used in the erection of precast beam bridges for span by span method of construction for precast beam girders like T beam, U beam, etc. This self-beam launcher is suitable for bridge construction over river, valley or highway and so on.
This type Beam launcher machine is suitable for the construction of bridge for roads, railways and other bridge erection construction site. Its main function is to lift the prefabricated beams, then transported onto the prefabricated pier. It has big difference from the general cranes. It requests high security.
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.
