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 Ransomes & Rapier and named after the 1957 Grand National winner, it began work in a Rutland iron ore quarry belonging to Stewarts & 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 recently 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. The cab is preserved at Rutland Railway Museum.
