The tyre trolley transfers the concrete segment to the rear of the launching gantry. The lifting trolley of the gantry lifts the concrete segment to the assembly position and the steeve hangs up the segment. After assembly, these segments tighten together with stressing wires, and the gantry put the beam on the pier and fulfill the construction of bridge segment. Based on the requirement of our client and the bridge conditions, the erection span and lifting capacity could be modified and customied for each machine.

Q:How does the bridging machine work?: Then, the beam is placed between the first and the second piers of the bridge pier by the conveying mechanism, is generally a few beams form a bridge, a bridge frame can make bridge machine move to between the first and second frame pier pier next beam. You'd better take a look at the actual construction process.

Q:Now the high-speed rail bridge frame span of the beam: The bridge erecting machine is a device for placing a prefabricated beam on a prefabricated pier

Q:Bridge erecting machine belongs to bridge or gantry crane: The bridge erecting machine is a device for placing a prefabricated beam on a prefabricated pier.

Q:The difference between double guide beam bridge machine and single beam bridge machine: Introduction of girder erecting machine:The utility model relates to a guide beam type bridge erecting machine, which is a special mechanical equipment which is used for lifting and transporting concrete precast beam pieces by lifting devices and mobile machines, which is used for lifting and transporting precast concrete beams.

Q:When the bridge frame is equipped with T beam, there are power lines above, we do not have the height of the bridge, so I do not know whether the power line to be removed.: Such as the bridge from the building, such as bridges under the crossing should not be required.

Q:Safety slogan for bridge erecting machine: Hello hello!Safety slogan for bridge erecting machine;1, safety first, prevention first!2, scientific development, security development!

Q:Our original home is the height of the beam is now 3m to 2.6 of the beam is not to the bridge before the support leg height: The front leg is to reduce a certain height. Do not know who you are using the bridge machine, and some of the front legs of the bridge machine can be dismantled section, and some have spiral support, so, but also with the design manufacturers, can not change their own. Once you have it, in case of any problems, the designer has no responsibility.

Q:Bridging machine belongs to special equipment: Special equipment refers to the safety of life, a greater risk of boilers

Q:How long will it take to set up the 30 - meter girder erecting machine on the highway: Erection of 30 m girder bridge machine total length of 56-58 meters

Q:I would like to ask what types of bridge machine: Bridge machine from the use of points, can be divided into highway bridge, railway bridge machine. Can also be divided according to the different structure, the name is more, for example, the auxiliary beam type, the whole frame, tunnel, etc.. Can also be based on the way to set the sub section of the assembly type, the whole hole, etc.
