Built by Bucyrus-Erie in 1969, Big Muskie was the world's largest ever dragline, being 487 ft (148 m) in length, weighing some 13,500 short tons (12,247 t), and hoisting a 220 cu yd (168.2 m3) bucket that could move 325 short tons (295 t) of material at a pass.
A dragline excavator is a heavy-duty excavator used in civil engineering and surface mining. It was invented in 1904, and presented an immediate challenge to the steam shovel (and its diesel and electric powered descendant, the power shovel. Much more efficient than even the largest of the latter, it enjoyed a heyday in extreme size for most of the 20th century, first becoming challenged by more efficient rotary excavators in the 1950s, then superseded by them on the upper end from the 1970s on.
The largest ever walking dragline was Big Muskie, a Bucyrus-Erie 4250-W put online in 1969 that swung a 220 cu yd (170 m3), 325 ton capacity bucket, had a 310 feet (94 m) boom, and weighed 13,500 tons.
The largest walking dragline produced as of 2014 was Joy Global’s digital AC drive control P&H 9020XPC, which has a bucket capacity of 110–160 cu yd (84–122 m3) and boom lengths ranging from 325–425 ft (99–130 m); working weights vary between 7,539 and 8,002 tons.[1]
