We supply reliable and flexible gantry crane for bridge construction. The crane is mainly composed of assembled main beams, outriggers, lifting mechanism, crane travelling mechanism, etc. The components are connected by pin shafts and high-strength bolts, which are easy to disassemble and transport. Compared with ordinary gantry cranes, this crane is convenient and quick to install, economical and practical. It is suitable for various road and bridge construction projects.
Uses of Gantry Crane for Bridge Construction
Two sets of gantry cranes can be equipped to lift precast beams, or a single crane with double spreaders to lift precast beams. The lifting weight of two cranes that lift at the same time is generally 450 tons, and the lifting weight of a single crane is usually up to 900 tons. The crane is composed of outriggers, crane running and lifting mechanism, which can realize all-round mechanized action.
This mobile gantry crane for bridge construction is mainly used to lift and move the precast beam from the beam making platform to the beam storage platform. After the precast beam is maintained, it will be lifted from the beam storage platform to the beam transport vehicle.
The gantry crane can complete the assembly and disassembly of the bridge erector, and it is also used to erect dry bridges with low piers.
Design of Rubber Tyred Gantry Crane for Bridge Construction
The beam lifting gantry crane adopts a gantry frame structure. When loading beams, the beam transport vehicle can enter the lower part of the beam lifting machine from the middle of the side legs of the machine. It is more convenient to lift, load and transport the beam, and to facilitate beam yard layout.
The rubber tyred beam hoist is fully hydraulically driven; the lifting mechanism adopts hydraulic winches; the steering system adopts independent steering of each traveling wheel group. The whole machine is controlled by the micro-electric control system, with good performance and high working efficiency.
- The operating speed of the lifting mechanism and the crane running mechanism is low to improve the alignment accuracy of the precast beam and reduce the impact on the structure of the crane.
- The internal space of the beam lifting machine should be large enough to suit the assembly of the precast beam and bridge erector.
- On the premise of satisfying strength, rigidity and stability, the design of the main steel structure should also consider disassembly and transportation.
- When two beam hoists are used to lift precast beams, the two machines must run simultaneously.
