100t 200t 300t 400t Bridge Girder Erection Machineother With Auto
Transmission Systems
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.
The bridge girder erection machine Features:
* Unique pin connection, firm and reliable, easy to install
* A-type fracture surface, continuous girder with low center of
gravity, convenient and reliable.
* The machine can accomplish the build of girders with carrying and
erection at the same time.
* Low deflection and high stiffness .
* Safe and reliable .
* High efficiency.

Bridge Erecting Machine Application:
The bridge erection machine can be roughly divided into highway
bridge erection machine and railway bridge erection machine
according to its use. It can also be divided according to different
structures. There are many names, such as auxiliary guide beam
type, integrated frame transport type, tunnel type and so on. It
can also be divided according to the erection method, segmental
assembly type, whole hole type, etc. There are also points based on
tonnage. Generally, the tonnage of highway bridge erecting machines
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.
