The Swiss ski resort Grindelwald - Kleine Scheidegg required a new snow machine for the winter season 2010/2011. To achieve this 4 pipes needed to be installed underneath the railway track.
This railway is used by more than 600'000 tourists every year, who wish to visit the "Jungfrau Joch" ("Top of Europe"). The contractor, Peter Roth (from Grindelwald) decided to employ his TERRA-HAMMER T 135 F to undertake these crossings.
After the first 135 ø pilot bore the bore channel was increased by an expander ø 203 mm (8"). The HDPE pipe ø 162 mm (6.4") was pulled in simultaneously. The other three crossings required smaller pipes, so they could be pulled in immediately with the T 135 F without an expander. These pipe sleeves were used for water, electrical power and control cables. Peter Roth was very satisfied with the successful pipe laying job which was finished within half a working day.
