Bridge launcher
Brief introduction
Now, China is implementing the great project of "One Blt and One Road" (OBAOR) and established the "Asian Infrastructure Investment Bank " (AIIB). Infrastructure construction are the main part in this great project, such as highway, railway, high-speed rail, metro / subway railway, crossing bridges, etc.
Bridge "T" girder is the key part of bridge building. From making, transporting, to installation, We offer customer One-stop Solutions, such as bridge launcher crane, bridge lifting gantry crane, bridge girder transporter (carrier), etc
Application:
Normally, this crane is for 50-250t weight bridge beam; mainly applied in highway project, express way project, etc.
The whole structure is of triangle truss type steel frame, which is suitable to erect various bridges, the skew bridge, curved bridge, cross bridge and long bridge, etc. Normall, This bridge launcher crane work with beam hoisting gantry crane, and beam transporter---integrating the work of bridge beam making, transporting, and launching. This design is of light weight, small windward area, easy transportation, easy assembly & disassembly.
