Liebherr mobile crane is just the job for Aussie dam dismantling

08.09.2021


A 60-year-old weir in Australia has been dismantled using a Liebherr LTM 1450-8.1 mobile crane – the first of its type in the country.

The low head dam, located on the Macalister river in Maffra, around 200 kilometres east of Melbourne, was refurbished by Australian crane contractor Advanced Cranes and Rigging.

Both the hoisting equipment on the structure and its concrete bridge were replaced using the eight-axle crane, which has been part of the Advanced fleet since 2020.

Restrictions at the site meant the LTM 1450-8.1 had to be positioned so that it could complete the hoisting process over the side, whilst remaining within the required working radius.

A steep slope, uneven terrain and an underground water tunnel made the search for a suitable crane position even harder. Additional crane mats were used to level the crane adequately.

“Our LTM 1450-8.1 was the first crane of this type delivered to Australia,” says Adam Tuddenham, managing director of Advanced Cranes and Rigging.

“Today it is still the only crane of this type in the State of Victoria and is delivering reliable, valuable services for us.”

The Liebherr 450-tonne crane can be described as a large fast-erecting crane since it combines good mobility with short set-up times on site. At the same time, it offers a long, powerful telescopic boom.
