Ruston-Bucyrus

From Wikipedia, the free encyclopedia

Ruston-Bucyrus Ltd was a engineering company based in Lincoln, England, that for 50 years manufactures Rope Excavators and Draglines. The company was formed from a merger of Ruston & Hornsby Ltd and American company Bucyrus-Erie makers of Mining excavators and steam shovels in 1930. The Company was sold off by Bucyrus-Erie in 1985. Ruston & Hornsby had a history going back to 1875 in the manufacture of steam shovels. They had supplied over 50 machines for the Manchester-Liverpool ship canal, and shipped machine all over the former empire countries.

Ruston-Bucyrus built larger machines for the British market to Bucyrus-Erie designs. The Bucyrua-Monigan 5W was a top seller for export by Ruston-Bucyrus, thus they started building it. This was a walking dragline, with either Diesel or electric powered options.

Following the split the firm was called RB Lincoln Ltd, before being sold and becoming RB Cranes in the 1990s.
