Big trout gets a big friend, and it's the biggest tunnel borer in world | The Standard

Out of the mist came one of the biggest and widest loads seen in the Snowy Mountains in more than 70 years - the first sections of the massive tunnel boring machine for the Snowy 2.0 pumped hydro project.

Even the Big Trout at Adaminaby had a big friend for a while as the large truck rigs passed through the small Snowy Mountains town in the early morning.

The whole Snowy Mountains Highway was closed from Adaminaby to near Kiandra for two hours as the large pieces of tunnelling parts were moved through.

The pieces were brought from Port Kembla, where they had arrived by ship from the tunnel borer machine manufacturer in Germany.

Motorists have been warned there will be more highway closures and temporary hold-ups as the Snowy 2.0 project gets into full gear.

Snowy Hydro said the oversize tunnel boring machine loads being delivered today were:

  • Gear ring probe drill and main seal. The dimensions are: 6.2m long, 6.1m wide, 1.530m high, 14 tonnes.
  • Front shield - Size and weight is 8.120m long, 3.95m wide, 3.81m high, and weighing 87 tonnes.

"We are very excited that the largest of the TBM parts are being delivered to site so we can start tunnelling for Snowy 2.0," Dean Lynch, Snowy 2.0 relations manager said.

"The TBM parts being delivered now will be assembled onsite starting next week and lifted into the concrete cradle that has already been constructed at the Main Access Tunnel portal.
