ALUMINIUM GANTRIES

Low maintenance - corrosion-free - sustainable

ALUMINIUM GANTRIES Low maintenance - corrosion-free - sustainable

SWARCO is Germany's only full-service provider of integrated solutions for aluminum traffic sign carriers. We offer the entire traffic sign carrier portfolio of aluminum gantries and cantilevers.

Their construction is based on the guidelines of the Federal Ministry of Transport (ZTV-Ing Part 9-1 (12(2012)) ) and the decrees of the individual federal states. Static calculations are available for verification.

GANTRIES AND CANTILEVERS
  • available in any span width
  • with or without walkway (retrofitting possible at any time without corrosion)
  • gap-free stem-transom connection for perfect fits without gap corrosion
  • the aluminum material substantially extends the operating life span (approx. 50 years) and drastically reduces maintenance requirements


STATIC AND DYNAMIC SIGNPOSTING SUPPORT

  • overbuilding of a four-lane federal highway possible with a one-piece transom - without bolted joints
  • transom cant to prevent deflection
  • sign holders are located below the catwalk and can be moved - re-signing possible without corrosion
  • can be modified to dynamic signposting (dWiSTa)


FLEXIBLE WALKWAY SOLUTION

  • walkways can be retrofitted at any time to a non-walkable gantry
  • bolted connection with latch is corrosion-free
  • sign brackets are located below the catwalk and can be moved
  • corrosion-free re-signing possible
GAP-FREE STEM-AND-TRANSOM CONNECTION
  • top connection plates are face-milled after the welding work
  • perfect fits and gap dimensions
  • so-called shear brackets can be bolted in order to be able to dismantle the stems, e.g. in the case of dynamic construction progress or after an accident, without demolishing the foundation base
  • face-milled top plate with gap dimension "zero"
  • no gap corrosion
  • ZTV-ING compliant


TRANSOM CANT TO PREVENT DEFLECTION

  • transom with cant welded in one piece
  • avoidance of deflection after load bearing of the signs
  • ZTV-ING compliant


ASSEMBLY

Aluminium gantries stand for quick assembly and minimum locking times: The low weight ratio (approx. 1:2) enables easy handling, which can be carried out with an assembly crane (truck). Pre-assembly is carried out on the verge or on site. The transom assembly is possible with a locking time of only a few minutes.


Advantages


Despite higher energy costs for the production of the primary aluminum, the energy compensation results in the course of the life cycle after about half of the lifetime. Aluminum structures therefore represent the most economical solution for gantries and cantilevers. Advantages are:

  • Good formability
  • widths of > 30 m possible without bolted joints
  • low weight
  • simple and fast assembly, only short road closings necessary
  • longevity due to corrosion-free material
  • minimal maintenance required
  • high investment security
  • sustainable eco-balance due to overall energy efficiency
  • excellent recyclability


Technical Details


Materials

SWARCO gantries and cantilevers are made of EN AW-5083H11 aluminum

Retrofitting

Retrofitting is possible any time, taking structural statics into account

Maintenance free

  • Rust proof

  • No preventive maintenance of e. g. zinc coating

Weight

Low weight, easy assembly of the entire construction

(only 1/3 of the weight of a comparable steel construction)

Lifetime

Lifetime of approx. 50 years without maintenance

Hot-dip galvanisation

Not required

Environmental impact

Aluminum does not require any surface treatment, thus imposes no environmental impact after installation
