A dragline excavator! This is the Bucyrus Erie BE1150 at Swillington near Leeds in the UK. It’s preserved by the ‘Friends of St. Aidans BE1150 Dragline’, a great bunch of blokes who look after this amazing bit of mechanical engineering.  1200 tons and a 215ft long boom – this is a BIG bit of kit, pity it’s no longer workable though.
