Bridge erection cranes mainly consist of the main beam, cantilever beam, under guide beam, front and rear support legs, auxiliary outrigger, hanging beam crane, jib crane and electro-hydraulic system. Applies to three different spans and single-span simply supported beam erection with high operating efficiency.
This type of bridge beam erection cranes can erect straight line, curve line(R is great than 2000m),the longitudinal slope less than or equal to twenty per thousands of 20m,24m,32m, composite beam and continuous steel structure. There is the construction of other working condition. But also provided by simple bracket erection, fixed-point lifting, lifting beam with good stability, high efficiency, safety, and reliability, easy to adjust variable cross and easy to operate.
Erect Bridge Crane mainly designed for highway and railway. According to the situation of present railway with less sub-grade, more bridges and tunnels which connected too closely, Design and manufacture the new box girder bridge girder launcher with double girder. Bridge beam Erection Cranes Mainly used for hoisting (lifting) of concrete girder in bridge construction (bridge building) of general railway and highway.
- Horizontal operation landing the beam in place at one time;
- Suitable for the construction of inclined(curved)bridge;
- Lightweight, convenient and quick transportation, installation and removal;
- Safe and reliable work, small longitudinal cantilever deflection;
- The legs are not landed on bridge deck when longitudinal moving, reducing the pressure on the beam/bridge deck.
