Overview
The Doka Cantilever Forming Traveller (CFT) is a rentable, modular system combining formwork and shoring to advance bridge decks by cantilever method. Its modular longitudinal trusses, integrated platforms and anchoring concept are designed to streamline assembly, operation and relocation on site.

Reduced costs

• System available for rent, avoiding upfront capital expenditure.
• Low number of separate parts shortens on‑site assembly times.
• Ergonomic design and standard components enable fast repositioning and short cycle times.
• Modular elements allow adaptation to varying bridge geometries and section widths.

Smooth project progress

• Single‑source supply of formwork and shoring reduces coordination interfaces.
• Project‑specific operating instructions detail all work steps and safety measures.
• Short delivery times due to rapid availability of standard system components.
• Optional instructor support accelerates commissioning and cycle optimisation.

Safety at all times

• Fully railed working platforms on all levels for safe access and operations.
• Hydraulic test‑loading of CFT anchorages prior to each pour.
• Slide bearings with permanent self‑locking action prevent unintended travelling on longitudinal gradients.

System — Optimised longitudinal trusses

• Longitudinal trusses are raised to provide increased headroom and better access to the slab edge.
• Horizontal pre‑assembly of trusses, ladders and catwalks at ground level is possible to reduce erection time.

System — Universal anchoring cross‑beam

• Suspension rods can be positioned flexibly along the cross‑beam to suit different bridge geometries.
• Asymmetrical cross‑beam configurations can be used where space is restricted by adjacent structures.
• Broad working platforms allow safe handling of suspension rods; pre‑assembly including platforms is feasible.

Modular design concept
The variable positioning of longitudinal trusses permits straightforward adaptation of the CFT to variable‑width or multi‑cell cross‑sections.

Pre‑assembled platform system

• Pre‑assembled platforms provided on all work‑deck levels.
• Integrated ladderways with ladder cages and self‑locking manholes.
• Generously dimensioned access routes for safe and efficient working.

Innovative drive unit

• Permanent self‑locking safety feature (slide bearings) guards against unwanted travelling — effective up to a 6% longitudinal gradient.
• Safety function is always active to prevent incorrect operation.

Bracing located on outside

• External bracing permits unobstructed top access, facilitating reinforcement placement and concrete compaction.

Complementary products

• Edge protection system XP.
• Guardrail posts and clamps.
• Access system XS.
