Lifting frames (“LF") and launching girders (“LG") are developed and used for placing precast post-tensioned concrete bridge segments to form viaducts and bridges. They are specially designed for use in restrictive construction environment to overcome limited access from ground. LF/LG is designed to comprise lifting

Their main application has been in Europe, but the method has now spread around the world and the technology has been applied to steel I-girder and box girder bridges as well. In the early 1960s, the “modern" approach to launching concrete bridges was developed. The first concrete bridge constructed by launching was
The fabricated launching girder is assembled on Abutment side approach in the launching direction.WORKS TO BE ENSURED BEFORE LAUNCHING ‡ Abutments and Piers to be completed including bed blocks. ‡ Dirt wall and fly wings of Abutment not to be concreted to facilitate movement of steel Launching girder.
23 Aug 2015 Full-text (PDF) | launching Techniques method will never become the most economical procedure for constructing all bridges. The Incremental Conference Paper (PDF Available) · April 2015 with 1,715 Reads .. “erection dollies," or trucks on which the girder sections were erected and launched. During.
Aim and Scope: This short paper, with its appendix, is primarily intended to provide. Risk Engineers with a simple reference tool to promote enquiries into the training, operational practices, safety and equipment associated with the use of launching girders (LGs) for viaduct and bridge construction. However, if it is known at
12 Apr 2009 the bridge deck and 5 kN/m on the launch nose girders. Differential settlement effects are limited to 20 mm between any two adjacent piers or abutments, and wind loads and differential temperature effects were limited to 70% of AS5100 requirements. A temporary bearing friction factor of 5% was used to
beam launcher for launching precast superstructure concrete beams, which is capable of launching 25 girders in a month. That amounts to about 500 metres of bridge approximately, which is one of the highest productivity norms achieved in India. In the PSC girders the usual method of placing and positioning of POT/PTFE
FM 5-277. CHAPTER 19. LAUNCHING BY SINGLE GIRDERS. It may be advisable to launch a panel bridge one girder at a time. This method is advan- tageous when launching from an existing bridge where piers are wide enough to take the ends of a new span, but the existing bridge is not wide enough to launch the new.
optimized initial investment. • reasonable construction cost (not necessarily the lowest). • architecture (aesthetics is a virtue and implies costs). • low impact on environment. • long service life and low maintenance. • continuous box-girders. • no internal expansion joints > sliding bearings. • high quality of design and
