FAQ Aug 15, 2012 Comments Off on What is Difference between Bridge Girder Launcher and Movable Support System

1. Bridge girder launcher is a equipment that helps put prefabricated precast girders on prefabricated piers. It lifts the precast girder slabs, transports them to specific location and drops them, so it is included in cranes. But there is a strict demand on the bridge girder launcher, because it needs to move on the precast girders (longitudinal movement of the bridge girder launcher).

?Three kinds of bridge girder launcher:

a. Highway bridge girder launcher

b. General railway bridge girder launcher

c. Passenger railway special line bridge girder launcher

 

2. Movable support system bridge making machine is a construction machinery of cast-in-place segmental prestressed concrete box girder with its own template, supported by box girder structure. It can finish a series construction from moving supports to casting mold.

 

Main features: high construction quality, convenient handling and low cost

 

In foreign countries, it has been widely used in construction of continuous beam in highway bridge and railway bridge projects, is an advanced construction way.

In domestic market, it begins to be used in highway and railway special line for passenger

 

Main parts: support mechanism, supporting truss girders, internal/external formwork and lifting mechanism of main girder
