“We outsourced a crane to do the job. There are only two of these size cranes in Victoria,” Jon Dunn of Dunn’s Twin City Cranes Wodonga told the Yarrawonga Chronicle.
A total of 15 people, including four from AGL Electric Company, worked on the project which, with considerable planning and execution, took two days.
“The whole project involved seven fully loaded semi-trailer loads of associated equipment and a five-hour drive from Melbourne to Yarrawonga.”
Yarrawonga’s hydroelectric power station at Lake Mulwala provides electricity to meet peak customer demand.
Commissioned in 1994, it has a generating capacity of 9.5 megawatts (12,700hp) of electricity. It is a run-of-river scheme using a Kaplan-type turbine. The station has two ESAC variable pitch turban alternators.
“We have 90-tonne cranes,” Mr Dunn, 44, formerly based in Corowa, said. “This one was a real big one!
“When we were involved in the new Federation Bridge (at Corowa-Wahgunyah, completed 2004) we appeared in The Free Press newspaper (in 2003 when setting up the barge).”
The 450-tonne crane is expected to be back in action in about two months to re-install the power station generator.
