Depending on the type and volume of work to be done, small or heavy-duty excavators can be employed. A typical excavator has three main components; an undercarriage for mobility, a 360-degree rotating cabin, and hydraulic articulated arms with a bucket. Excavators are classified on the basis of the carriers and working mechanism.

An endless track crawler mechanism has a plurality of bogie yokes that each contain a pair of rotatable bogie rollers and are pivotally mounted on two opposite sides of a chassis of said mechanism to support said chassis. At least two of said bodie yokes are affixed to said chassis by a bogie shaft56 that provides shaft limited vertical translation of said two bodie yokes.

An Italian company, Fiorentini, produced dragline excavators from 1919 licensed by Bucyrus. After the merger with Monighan in 1946, Bucyrus began producing much larger machines using the Monighan walking mechanism such as the 800 ton 650-B which used a 15-yard bucket. Bucyrus' largest dragline was Big Muskie built for the Ohio Coal Company in 1969.
