Customized 240t Bridge Erecting Machine Improves The Efficiency And
Safety Performance
The introduction of bridge erection machine:
The bridge girder erection machine consists of main girder, crane,
front legs, rear legs, front leg cylinder, rear leg cylinder and
the transverse connection of front, middle, rear legs. The control
part is composed of hydraulic system and electric control system.
The bridge girder erection machine is characterized by reasonable
compact structure and convenient installation, the main standard
girder is connected by pin connection. The double girder structure
is connected between the two frame girders by weldedpipe.
The bridge girder erection machine not only can meet the standard
set up, but also it can meet the cross curve erection, variable
span erection, span continuous beam, composite beam, continuous
steel etc. In addition to bridge erection, simply supported girder
erection and point lifting, it is characterized by good stability,
high efficiency, safety and reliability, variable span convenient
adjustment and convenient operation and etc.
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.
