Mur Bridge S 35, Austria

Mur Bridge Frohnleiten - For the construction of the Mur Bridge near Frohnleiten, the new VARIOKIT heavy-duty truss from PERI has set new standards in shoring operations.
Mur Bridge Frohnleiten - For transferring the heavy loads over the almost 40 m span, the truss arrangement and spacings can be flexibly determined using a metric grid configuration.
Mur Bridge Frohnleiten - Modular shoring assembly: VARIOKIT system components were pre-assembled on the ground to form truss segments and placed into intermediate storage with the crane. Three such segments were subsequently coupled to create a 37 m long truss unit and lifted over the Mur by means of a mobile crane.
Mur Bridge Frohnleiten - Due to the standardised connections with only a minimum of tool usage, the VARIOKIT construction kit system is easy and simple to assemble.

Kundens fordeler

  • Maintaining the construction schedule through the rapid availability of materials and short assembly times
  • High load-bearing capacity of the VRB heavy-duty truss with comparably low deadweight
  • Easy assembly due to simple alignment of the pairs of trusses and high degree of accuracy
  • Time and cost savings during lifting operations due to the low weight

The VARIOKIT heavy-duty truss system with the variable starting frame has set new standards in shoring operations. It reduces the amount of assembly work required especially for inclined supporting structures. The accuracy of fit as well as aligning the pairs of trusses also make a convincing case.
