Highway-Railway Dual-Use Single Beam Bridge-Erection Crane (NFD180T/40M)

Highway-Railway Dual-Use single beam Bridge-Erection Crane (NFD180T/40M)

NF walking type bridge erection machine has two forms, balance and counterweight style. They are used for laying the straight bridge, skew bridge and curved bridge. Can meet the requirement for beam feeding under the bridge and in the end of the bridge. It also can carry the beam into the position once to achieve the general yielding moving and laying. Especially for laying beam to water bridge, high bridge pier and wide bridge floor.

It has two main parts, which are main machine and beam mobile trolley. It is the 3rd generation bridge erection machine which is based on many years design, manufacturing and the usage of railway& roads bridge erection machine.

Walking double guides bridge erection machine has the truss to support itself and hinge pin to connect the units. Main guide beam has a light leading beam to safely pass the hole. Using the walking hole passing, the machine doesn't need lay the rail, and the point moving support can adjust the different crossing bridge installation within 50 meters, which can make the laying once in the position. It has the length wise and cross wise walking device, length wise walking device and lifting vehicle to realize the 3D motion of hole passing, lifting and beam laying. The control system is smart and stable, which promotes the safety, stability and precision of the machine. Assembly style is economic and easy to load and unload, transport, and move.
