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.
