Take a virtual walk through our Underslung Form Traveller (UFT).

This new virtual tour provides a closer look at an Underslung Form Traveller developed for the balanced-cantilever construction of concrete box-girder bridges.

Explore the complete working environment—from the main load-bearing structure and formwork beneath the bridge deck to the suspension systems, working platforms, access routes and support components. The tour allows you to move freely around the equipment and examine details from perspectives that are not always accessible during a conventional site visit.

The virtual environment is a practical tool for presenting the system, supporting technical discussions and helping project teams understand a proposed equipment solution—wherever they are located.

Watch the tour and step inside the system.

🔴 OVERHEAD MSS - Movable Scaffolding System 🔴
💪14 DAY TYPICAL CYCLE PER BRIDGE SPAN 💪

✅Overhead MSS is another Movable Scaffolding System solution that is also suitable for concreting span by span BOX or DOUBLE T DECK sections.

✅Box Overhead MSS typically consists of a resistant structure supported by the columns, from where the formwork is suspended. The resistant structure normally includes two main I-beams, a set of transverse beams and the noses and supports.

✅When the solution is used for concreting box section decks, the internal formwork is identical to the internal formwork used in underslung MSS.

✅The Overhead MSS main supports are designed in each case to adjust to the geometry of the columns in each project and the way the reactions should be transmitted to the concrete.

STRUKTURAS has extensive experience in designing different support configurations for overhead MSS.

The most common support solution consists of assembling support legs directly on the column, in which case the legs are connected to the concrete using embedded anchors.

Other solutions less frequently used have profiles passing through the column walls, collar friction or even precast concrete legs which becomes lost inside the deck structure.

♻️ 🏗️ ⛔ Span by span demolition
of the bridges using the
MSS Movable Scaffolding System

Contractors Eiffage , Implenia , Max Wild GmbH , Plannerer GmbH Das Abbruchunternehmen and Arlt Bauunternehmen GmbH are using this demolition method for their client Die Autobahn GmbH des Bundes

The demolition of the old bridge with MSS is an effective and safe solution:
- Minimal intervention to existing infrastructure.
- Using MSS for demolition allows the existing highway to remain open throughout all of the demolishing period.
- MSS allows the existing railway to remain open throughout most of the demolishing period.
- The MSS could be assembled on the ground and later could be lifted with 4 strand jacks.
- After finished demolition MSS could be lowered with 4 strand jacks on the ground for safe and productive MSS dismantling.
- The challenging MSS installation conditions can be carried out by professional site crew from Strukturas.
- The engineering challenge is to avoid an overload of the superstructure during the demolition and to ensure a safe load transfer within the load capacity of the MSS.
- After the demolition this same MSS could also be used for the construction of the bridge deck. This approach saves time and resources, making the construction process more efficient.

🔴BALANCED CANTILEVER🔴
construction METHOD with overhead FORM TRAVELLER system

This solution most commonly used for casting bridge and viaduct decks built
with the cantilever method whose span varies from around 60 to 250 meters in length.

A standard Overhead Form Traveller is normally designed to be used in casting segments up to 5 meters in length and up to around 300 tons in weight.

For longer or heavier segments, “tailor-made” Form Travellers can always be designed to work in these special conditions.

Launch back system allows the Form Traveller (FT) to be disassembled close to the hammerhead, after being used in casting the deck’s last segment.

This procedure streamlines operation and minimizes cost!
