Eastlink Tunnel, 2007

Intro

Thiess John Holland who constructed the Eastlink tunnels required 2 x heavy duty mobile scaffold systems that followed the pouring machine on rails. We built the mobiles out of Layher Scaffolding that weighed 10 tonnes each

Solution

A number of constraints made this no easy feat and would not have been possible with other scaffold systems.

Firstly they had to maintain the 7.5m traffic opening through the centre of the tunnel while at the same time only running on the existing, single track down either side.

They needed to be able to drive the mobile on a slope up to 5.1 degrees

Our solution was to design a special frame for the Scaffold to sit on that could have special mechanical casters bolted to it.

System

We provide intelligent solutions for anything from iconic buildings, refineries, tanks and tunnels to shipping, aircraft hangers and much more. Many scaffolds can be prebuilt and craned into position due to the rigidity of Layher’s unique connection technology. Our accessories provide further for areas such as temporary protective roofing and cladding systems.
