Yallah-bound 365-tonne megaload moved by four prime movers

The third and final piece of one of the biggest oversize and over mass movements ever on New South Wales roads was recently completed in the Illawarra.

A massive cross-agency effort oversaw an enormous convoy transfer a 366 tonne gas generator 18 kilometres from Port Kembla to the site of EnergyAustralia’s new Tallawarra B Project at Yallah.

The generator, which is approximately 13 metres long by 4.20 metres wide and 4.5m high, was transferred using two 16×8 metre trailers with beam set lugged by four prime movers.

The lead trucks, Kenworth T509s, were from heavy haulage specialist Lampson Australia, who in partnership with Transport for NSW, facilitated the massive move with Regional Customer Network Coordination, Freight and Traffic Management Centre teams working alongside NSW Police and traffic control provider Traffic Logistics.

Two of the prime movers were tasked with pulling while the other two, a Mack Titan and a Kenworth C501, pushed the megaload.

The overall size of the truck and trailer combination was 121 metres long, 5 metres wide and 5.7 metres high.

Total mass equaled 786 tonnes.

The complicated 6.5-hour operation commenced late Saturday, on 19 November and continued into the early hours of Sunday morning. It required contraflow traffic arrangements along sections of Springhill and Five Islands roads.

Sections of roads including the M1 Princes Motorway, Princes Highway, Five Islands Road and Springhill Road were temporarily closed for the convoy.

Support vehicles in the convoy included two mechanics vehicles, three pilot vehicles, three NSW Police vehicles, one TfNSW operational vehicle, one Traffic Control Truck Mounted Attenuator vehicle.

The megaload also had to be lowered at sections along the route to fit under road and train overpasses at Springhill Road and the M1 before being raised back up to continue at travelling height.

It’s the third and final transfer, following the movement of a 370-tonne turbine in May and a 250-tonne transformer in October to the EnergyAustralia site near Lake Illawarra ahead of its opening for the summer of 2023-24.

Touted as Australia’s first hydrogen and gas capable power plant, Tallawarra B Project, which is projected to contribute $300 million to the state economy, will deliver power to an additional 150,000 NSW homes.
