RopeCon® StrengenWhere tunnel excavation material takes the straight line.

Customer requirements:

The Strengen motorway by-pass tunnel project in Tyrol, Austria, was expected to produce approximately 850,000 m³ of rock excavation material which had to be taken to the designated dump. Transportation of the material to the dump was complicated by the fact that a river, a very busy road and a railway track were in the way. A conventional conveyor would have required a long bridge structure to cross these obstacles.

115,000 truck journeys along with the associated emissions of noise, dust and CO2 were no option for the removal of the excavated material. ARGE Tunnel Strengen thus went looking for a different approach to transport the highly abrasive quartz.

 

Our solution:

Strengen was the first RopeCon® project ever: With this new concept of material transport it was possible to span the river, the road and the railway in one straight line. The belt of the RopeCon® was turned right behind the discharge point so that no residual material would fall off the belt on its way back. In its first project ever, RopeCon® more than lived up to the expectations and certainly stood the test as a clean, quiet, efficient and straight-forward transport solution.
