Span by Span Launching Gantry   is used for cross-sea, cross-river bridge, high-way and rail bridge projects. The first span by span LG made by Tolian was used for Sutong Cross-sea Bridge in the year of 2003. 

Launching Gantry  (LG)  is used in the erection of full span concrete pre-cast box girder for high speed railway bridges. They combine with a Tyre Trolley for concrete box girder erection. A LG can be used for normal concrete box girder erection as well as first span and last span erection, curve construction, various box girder sizes and short distance self-launching capability, ideal for limited space without the need for additional equipment. A LG can easily be dismantled for transfer between sites and can be transported by multi-axle trailer over viaducts,  embankments and through long stretch tunnels.

The MSV is used to transport segments and other heavy objects, namely, soil  bucket, generator set, people carrier module, inside and outside the tunnel.
