An Enerpac (A Division of Actuant Corp) Strand Lift system capable of safely positioning huge loads to accuracies within fractions of a millimeter is being employed by VDM Group in constructing Australia’s largest-ever magnetite mining and processing operation.
CITIC Pacific Mining’s $US4 billion Sino Iron Ore project in Western Australia involves 12 of the biggest iron ore processing mills ever built, which are manufactured in China and transported in sub-assembly form for precision positioning onto their bearings 21 metres above the ground.
The powerful PLC-controlled synchronous Strand Lift heavy lifting systems hoist loads of thousands of tonnes where access is restricted, overhead space is limited or maximum stability is required. Applications range from mining, energy and petroleum sites onshore and offshore, through to the placing of weapons systems in submarines, positioning machines in tunnels and erecting bridges and viaducts.
The Sino Iron Ore Strand Lift System specified by VDM Group for CITIC Pacific and MCC Mining involved four 444tonne 37 Strand, Strand Jacks, with Recoiler and Palm Tree Control Systems positioned on the prefabricated steel structures above the position to which the ball malls are delivered by road from the Cape Preston wharf to the mill site at Cape Preston concentrator area in Western Australia’s far northwest.
The mills travel overnight for several nights at about 1 km an hour on multi-wheel transporters before being placed beneath the Strand Lifting equipment for raising 6 metres clear of the transporters, then lowering 6 metres for positioning onto the mobile transporter that is driven laterally into position on rails after the multi-wheel transporter is removed.
