Against vigorous competition from a number of competitors, Ainscough Industrial Services won the contract to erect a new coal stacker/reclaimer at Drax Power Station, which included dismantling and scrapping of the old machine.
Ainscough Industrial provided a skilled team of fitters, riggers and welders to erect the 600 tonne machine, over a period of almost 12 months.
The main structure of the machine arrived on site in approximately 22 pieces, with the remainder stored off-site in numerous freight containers and brought to site as and when required.
To minimise working at height, sub-assemblies were fitted out with as much of their ancillary steelwork and fittings as possible at ground level, before being lifted into place.
The heavy lifting was carried out by a Liebherr LR1130 and a Kobelco CKE600.
Many of the components had not been fitted with lifting points and, therefore, AIS designed, fabricated and fitted these and, in addition, organised a third party NDT inspection.
The heaviest lift was the inner boom assembly which included the lower mast sections and weighed 49.5 tonnes.
This was carried out with the LR1130 on 38m of main boom at a 9m radius.
The main boom was twin lifted by both the LR1130 and CKE600 cranes.
A procedure for dismantling the old machine was supplied by the client, together with calculated weights and centre of gravity positions.
Most of the dismantling work was completed solely by the LR1130, leaving the CKE600 to aid in the ground level cutting up of pieces to make them small enough to transport.
Throughout the entire project, Ainscough Industrial Services supplied all supervision, labour, craneage, site accommodation and storage, fencing, access and rigging.
