Heavy Capacity Truss Type Launching Bridge Girder Erection Machine
Bridge Girder Erection Machine Description
Bridge girder erection machine merges an adaptation of a wide range of work, excellent performance, convenient operation, safety structure into a single whole. It has the steel structure of rail type precast beam hoisting rack equipment. This product can be used not only in plain construction, but also to meet the construction of mountain highway slope, small radius curved bridge, skew bridge and tunnel bridge requirements.
The bridge girder erection machine 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.
