Ruston Bucyrus was formed in 1937 after the merger between Ohio based Bucyrus Erie and Lincoln based Ruston and Hornsby Ltd. The company soon became recognised for their large excavators and by the mid century were one of the leading manufacturers of mining and quarrying machines.
Within the industry the RB machines were viewed as one of the better quality and longer lasting machines of their time. The Face Shovel, often referred to as a ‘crowd shovel’, was mainly used for shovelling materials from high faces of heaped material such as coal or gravel. This made the RB19 suitable for working railway yards, it was often used to load gravel into wagons which would then later be transported for railway embankment repairs or the laying of new track.
