Intended for the construction of a deck secondary lining. The slab formwork is engineered to resist pressure given by concrete thickness of more than 2 meters. Machine can be equipped by a service gantry with a concrete distribution system. This allows to speed up the work of the operators, guaranteeing at the same time Health and Safety.

The transport traveller is designed to work with more than five slab formworks. In this way is possible perform a continuous secondary lining, relocating sections of slab formwork which other sections are in casting phase.
