Sundew (dragline)
From Wikipedia, the free encyclopedia
Sundew was a large electrically powered dragline excavator used in mining operations in Rutland and Northamptonshire in the United Kingdom.
Built by Ransome and Rapier and named after the 1957 Grand National winner, it began work in a Rutland iron ore quarry belonging to Stuarts and Lloyds that year. At the time of its construction Sundew was the largest walking dragline in the world, weighing 1675 tons. With a reach of 86 metres and a bucket capacity of 27 tons the machine was able to move a substantial amount of material in a relatively short period.
Propulsion was via two large moveable feet which could be used to "walk" the dragline forwards and backwards, while directional control was provided by a large circular turntable under the body of the machine.
Sundew remained until operations at the quarry ceased in 1974 and plans were then devised to relocate the machine to a recenltly opened British Steel quarry near Corby. At a cost of £250,000 and taking two years to complete it was decided that dismantling, moving and reconstructing the machine was not a viable option, and so over a nine week period in 1974 Sundew was walked thirteen miles from its home near the village of Exton in Rutland to a site north of Corby. During the walk the dragline crossed three water mains, ten roads, a railway line, two gas mains and a river, before finally reaching its new home.
As part of a major restructuring of British Steel in the late 1970s the Corby site was closed down and there was no longer any need for a large dragline to assist in the recovery of iron ore. On July 4, 1980 Sundew walked to its final resting place and the huge boom was lowered onto a purpose built earth mound. There it remained for seven years until being scrapped over a six month period from January to June 1987.
