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.
