Higher working efficiency
a) There is traveling rail together with main girder, trolley and longitudinal crane. So, it is no need to lay traveling rail more. In this way, a lot of auxiliary materials are saved and production time is also saved.
b) The bridge erection crane has higher working efficiency, with 6~8 pieces girder erection every day, based on enough concrete plate supplying, skilled operator and good condition at site.
More flexibility
a) It is symmetrically designed. Two way girder erections can be realized without split and slewing at original place.
b) Use one meter of hydraulic jack for front leg and rear leg. This design improves working efficiency, safety and flexibility largely.
c) Erect skew bridge by inclined way. Apply rotary face flange to connect each mechanism and structure, to erect 0~45°skew bridge. Side beam can be positioned one time for over 320m curve radius bridge.
Easier assembly and disassembly
a) Each structure is connected by pins and bolts to facilitate assembly.
b) Normally one set of launching crane can be assembled within 7days.
6. Plentiful experiences in this field
a) Our chief engineer Dr. chen is professional and very famous in China to design launching cranes.
b) The bridge launching girder is one of the highest market shares manufacturers in China, especially in Yangtze River Economic Delta, you can see our products everywhere.
