Strukturas, your partner for turnkey projects, worldwide.
Strukturas was founded in 1991 as a continuation of Olav Opedal AS, an Aker owned company specializing in construction and mechanical engineering.
Strukturas history therefore dates back to the 1960s with long standing traditions and
considerable experience.

• in situ casting of full spans
• TT or box cross sections decks
• Special solutions for special bridge
projects
• Hydraulic operated main functions
• Labor saving solutions
• Easy to adjust to radius, slope and
span variations
• Easy installation of the rebar deck
prefabricated parts
• Can be made symmetrical
Movable Scaffolding System Overhead Solution

NEXTPREVIOUS
• Supported on top of columns
• External formwork panels suspended
by hangers and threaded bars from
MSS main structure
• Formwork can be designed in special
cases to open horizontally like in a
drawer rather than rotate around the
hangers
• Can be made symmetrical
• Usually easier to assemble behind the
abutment
• Usually easier to move from one deck
to the parallel one

• One concept
• Many different applications
• Usually made to max. 5m length segments, but may be made to measure
• Segment weight typically range in between 80ton and 550ton
• Easily adjustable to the segment variations
• Reduced weight, saving prestressing
• Easy to assemble

NEXT
• Simple solution to support the precast concrete segments
• Two independent halves only connected by the gantry crane, allowing to easy transversal adjustments
• Hinge connection makes possible to be used at decks with horizontal radius as small as 75m
• Hydraulic underslung supports allows correction of any misalignments
Launching GantryOverhead
MENU END
PREVIOUS
• Solution especially suitable for situations where the space bellow the deck is limited and also if there are significant variations in the deck width
• The Combo Launching Gantry version allows for the assembling of precast segments both by the in fill method and the cantilever method
• Utilization of special hinges to run the system with horizontal curves up to 350m and spans lengths above 50m
Formtraveller Segmental
MENU END
• Simple steel supporting structure equipped with a lifting unit
• The lifting unit can be equipped by winches or strand jacks depending of the elevation height and segment weight
• Launching and leveling hydraulic operated
Full SpanLaunching Method
MENU END
• Especially suited for projects that require minimal deck deformations and fast construction
• The Full Span Launching method is part of a wider set of devices that operate all together as the gantry crane/straddle carrier and the special multi wheeled transporters
• Capacity: 500-1800ton
• Spans up to 60m
Beam Launcher
MENU END
• One of the most commonly used construction methods for standard bridges
• Cost efficient, fast and technically flexible solution
• Specially suitable for bridges and viaducts with very high columns and difficult access conditions
