Dragline buckets are used on dragline excavators or simply 'draglines'. Smaller draglines are used for road and port construction and larger ones in mining. Draglines are among the largest mobile equipment ever built on land.
A dragline bucket system consists of a large bucket suspended from a boom and wire ropes and is maneuvered by means of ropes and chains. The hoist rope is powered by a large diesel or electric motor and supports the bucket and hoist coupler assembly from the boom. The dragrope is used to move the bucket assembly horizontally. The bucket is controlled by maneuvering the hoist and dragropes.
The first dragline was invented in 1904 by John W Page, partner of Page & Schnable Contracting, for digging the Chicago Canal. By 1912 he realized building draglines was more profitable than construction and page Engineering Company was born. They invented the arched dragline bucket, a design still used today.
