Concrete Launcher Trussed Type Bridge Girder Erection Machine
Bridge Girder Erection Machine Description
Bridge Girder Erection Machine 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.
It 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.

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.
