Composite forming carriage

The adaptable travelling composite bridge-deck formwork from a single supplier

The Doka composite forming carriage makes for fast, safe construction of bridges on which a concrete deck slab is joined to a steel superstructure. The travelling composite forming carriage carries a large area of pre-assembled composite bridge-deck formwork that can be cycled without being dismantled. It stands out for its excellent adaptability to all circumstances, low-cost assembly from rentable standard components, and its high workplace safety.

Reduces investment costs
by using rentable standard components 

  • small number of versatile, combinable component parts
  • ease of assembly
  • fast closing and opening of formwork
  • high safety standards for rapid working

Smooth construction workflow
thanks to easy handling 

  • low dead weight and high load capacity
  • pouring in a weekly cycle
  • entire unit is travelled in one piece
  • is adaptable to slender structures as well

Comprehensive tailor-made solutions
for widely differing shapes of bridge 

  • high-calibre solutions for all steel composite bridges, planned and supplied by a one-stop supplier
  • operationally reliable, as the forming carriages, shoring towers and working platforms are all designed to work together seamlessly

The new System beam 5.00m NG allows the Composite forming carriage to be adapted to the structure geometry even more flexibly.



Simple system-grid

In the longitudinal direction of the bridge, the increment-grid of the Doka composite forming carriage is dictated by a 5 m long and 2 m high longitudinal girder. In the transverse direction, two transverse frameworks joined by an adjustment zone (compensation girders) permit any desired dimension. The adjustable spindle struts, and the large number of bolting positions in the steel girders, together make for optimum adaptability of the composite forming carriage. The new System beam NG allows more flexibility with the transverse frameworks in the longitudinal. This means that the transverse frameworks can be better positioned to take account of loads or geometrical parameters. In this way, the Composite forming carriage can be adapted to the structure geometry even more flexibly.

Safety on the structure

With its suspended finishing-work platform levels, the Doka composite forming carriage provides a high standard of safety. Only a few extra safety components are needed to create the ideal basis for an all-round enclosure.

Roller supports for inside formwork

  • for forward-jacking the inside formwork using the 'roller-drawer principle'

Unlimited adjustability options

  • cantilever arm formwork can be adjusted in all directions by means of spindle struts
  • formwork is easy to close and open, using a two-part anchoring system

Formwork systems for composite bridge-decks

Overslung composite forming carriage

This, the standard type of carriage, is a fast and safe way of constructing the concrete decking of composite bridges (on steel superstructures).

Underslung composite forming carriage

By providing barrier-free access to the entire roadway deck, this type of carriage ensures a high standard of safety, especially on wide bridge cross-sections with diagonal struts.

Bridge formwork ParaTop

For shorter superstructures and medium-length bridges involving only a few repositioning cycles, the crane-shiftable Bridge formwork ParaTop is available.

Cost-saving custom solutions

On request, the Doka Formwork Experts will also plan and design constructions for situations where space is severely limited, or for unusual cross-sections.
