Product Description:

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:The difference between double guide beam bridge machine and single beam bridge machine
Single beam bridge machine:The single girder bridge girder erecting machine adopts a single bearing beam, and the bridge erecting machine is composed of a single main beam, a supporting leg, a hanging beam trolley, a moving mechanism, a transverse moving mechanism and an electric control system. Main girder structure generally adopts box type structure of light weight, high stability of the beam, the guide beam can be moved up and down, back and forth, transverse, achieve a heavily beam beam falling in place, continuous erection line, line, curve and other different types of bridges.
Q:What is the double guide beam bridge machine
The bridge erecting machine is used for the road concrete beams, and is also used for a railway concrete beam. Common bridge machine generally has three legs and two support, from front to back, called the auxiliary leg, the front of the house, the middle leg, back and rear support legs. The main working conditions for the frame beam conditions, through the hole conditions, generally for the walk through the hole, the beam to beam beam with the working principle of the text is not clear.
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.
Q:How much is a bridging machine
Maximum working deflection: maximum deflection at midspan: 70mm longitudinal cantilever deflection: 1260mmFulcrum of the largest reaction (unilateral fulcrum) front leg: 110t leg: 135t rear leg: 70tTotal power capacity: 90KWMaximum lifting weight: 150t
Q:Bridge erecting machine belongs to bridge or gantry crane
Bridge crane belongs to the bridge crane, which is a large classification, I plant is specialized in the production of bridging machine, Kaifeng Hongda Luqiao equipment factory, the production qualification clearly defined above.
Q:DJ180 bridge machine how to run?
Four. When the bridge crane carries the concrete beam, the front leg part of the bridge crane is required to be fixed by the hand pulling block (5T).Five, when installing the bridge with the upper and lower longitudinal slope, the longitudinal displacement of the bridge erecting machine should be prevented from sliding. For example: the triangle iron for protection on wheels before and after, especially in the leg from the beam end is near, shift to the attention of control.Six, after the erection of the bridge crane must be suspended hanging crane operation, but also can be used to test the concrete beam, bridge erection machine running in place to start the installation work.
Q:What are the advantages and disadvantages of the bridge erecting machine
High lifting height, easy installation. But in the transition to the higher requirements of the road (height, width, bearing capacity, etc.).
Q:Special equipment (gantry crane and bridge machine) forensics problem
Specifically, it is located in the special equipment inspection institute (hereinafter referred to as the quality and Technical Supervision Department)
Q:A bridging machine requires several special operators
Other construction workers 10~20 ranging. See the specific operation of the type of equipment.
Q:What kind of machinery is the bridge? Bridge or gantry crane
Bridge crane is a bridge crane, bridge crane is also a crane, but not a bridge crane, the harsh conditions of its requirements
