The excavation in the London Clay is executed by the ripper bucket. The bulk material falls on the natural floor and slipping downwards into the main tunnel, where it is hauled by trackless vehicles.
With the achievement of the Uphill Excavator, the jury appreciates the increase in safety and the fact that the time for connecting stations under regular operation can be limited to a minimum. However, also the savings in time and money by a fast and safe operation is more than considerable.
Overall, this machine fits perfectly into the portfolio of GTA Maschinensysteme GmbH which could already shine with clever solutions for tunnel refurbishment or even in the excavation of the St. Gotthard tunnel. This expertise comes from a long tradition in the underground mining industry.
