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.
