Bridge Girder Launching Gantry Crane High Efficient River Cross Sea 5m / Min 50M
High Efficient River cross sea bridge girder launching gantry crane
launching gantry crane Description
launching gantry crane applies to highway, railway bridges to the construction site of bridge construction, its main function is to mention prefabricated good beam slice and delivered on prefabricated good piers.it and general meaning cranes have very big different, high safety requirements.
launching gantry crane consists of main girder, crane, front legs, rear legs, front leg cylinder, rear leg cylinder
and the transverse connection of front, middle, rear legs. The control part is composed of hydraulic system and electric control system. The bridge girder erection machine is characterized by reasonable compact structure and convenient installation, the main standard girder is connected by pin connection. The double girder structure is connected between the two frame girders by welded pipe.

FAQ
Q. What's the information should I provide when inquiry?
More details or drawings, better.
A: Lift capacity B: Concrete Beam Span C: Turning Radius D: power source or other specials you give us will be more appreciated.
Q. Can this type work in hazardous environment?
A:Sure! We can customize for you, acid proof or explosion proof, no problem for that.
Q. How can we install the crane?
A:Our senior engineer can be your side to do the installation guide service and training. Moreover, our best sales can visit your country.
Q. Notes:
This highway construction crane can be rail type and step type. The rail type crane is mainly used for lifting of beams with length not more than 30m. While the step type crane need no rails, which has no pressure and damage to the highway beam/bridge because the legs can be landed on the supports.
