250 Ton 300t High Speed Railway Bridge Erection Machine Continuous Beam With Low Center Of Gravity
Highway Bridge Erection Machine Application:
The bridge erecting machine can be roughly divided into highway bridge erecting machine and railway bridge erecting machine according to the use. It can also be divided according to different structures, and there are many names, such as auxiliary guide beam type, frame transport integrated type, tunnel type and so on. It can also be divided according to the erection method, segment assembly type, whole hole type, etc. There are also points according to the tonnage. Generally, the tonnage of the highway bridge erection machine is relatively small, generally less than 300 tons. Railway bridge erecting machines, especially high-speed railway bridge erecting machines, generally have a relatively large tonnage, 450 tons and 900 tons, which are very common.

The composition of bridge erection machine:
The bridge erecting machine is mainly composed of the arm, the No. 1 hoisting trolley, the No. 2 hoisting trolley, the No. 1 column, the No. 2 column, the No. 3 column, the hydraulic system, the electrical system, the diesel generator set and the safety protection monitoring system.
The beam is transported by the beam transporter to the rear of the bridge erecting machine to feed the beam, the hoisting trolley lifts the girder to pull the beam, and the position of the box girder is fine-tuned in the air. It can erect 32m, 24m, 20m double-line whole-hole box girder, adapt to erect minimum curve radius R5500m, adapt to erect maximum longitudinal slope 20‰, rated lifting weight 900t.
