In the field of bridge construction, rtg gantry crane is mainly used for carrying, hoisting and assembling large prefabricated elements. The prefabricated elements of this kind of bridge are relatively large such as bridge box beams, T beams, concrete beams and so on. Because of its high mobility and lifting capacity, the rtg gantry crane plays a very important role in the process of bridge construction.
1. Handling and storage in the precast yard
In the process of bridge construction, there are many bridge structures such as segment beams, box beams, etc., which are produced in the prefabricated yard and then need to be transported to the construction site by rtg gantry crane. This process includes rtg gantry crane that need to move the prefabricated beams from the production area to the storage area or directly onto the transport vehicle. In addition, the rtg gantry crane can also optimize the space utilization of the precast yard, and stack the precast beams with high precision to improve the utilization rate of the site.
2. On-site lifting and assembly
In the process of bridge construction, rtg gantry crane can lift and assemble large bridge components. Especially in the construction of road or railway bridges, the rtg gantry crane can accurately place the bridge deck structure. For the segment bridge, the rtg gantry crane can be moved between multiple operating points to efficiently complete the hoisting and docking of the segment beam.
3. Bridge reinforcement and maintenance
Bridges are in need of regular maintenance. In bridge maintenance and reinforcement projects, rtg gantry cranes can be used to remove and replace bridge bearing components such as steel beams and supports. At the same time, for Bridges that need to be strengthened or widened, the rtg gantry crane can flexibly carry the prefabricated parts and assist in installation.
1. Flexible mobility
Different from the rail gantry crane, the rtg gantry crane can move freely on the bridge construction site, without laying the track, and is suitable for different construction areas.
2. Strong lifting capacity
The rtg gantry crane can be designed with different lifting capacities according to the construction needs, so as to safely lift large prefabricated beams and steel components.
3. High efficiency
Compared with the traditional crane, the rtg gantry crane can lift multiple components at the same time, thereby improving construction efficiency and helping the project to be completed on schedule.
For long-span bridge, viaduct, railway bridge and other projects, rtg gantry crane is an ideal choice to improve construction efficiency, reduce costs and improve construction safety. Contact us for professional advice!
