Although considered more primitive than wheel-based forms of transport, on the type of territory where the travois was used (forest floors, soft soil, snow, etc.), rather than roadways, wheels would have encountered difficulties which would have made them less efficient.
Big Muskie was the world's largest ever dragline. Built by Bucyrus-Erie in 1969, it was 487 ft (148 m) in length, weighed some 13,500 short tons (12,247 t), and hoisted a 220 cu yd (168.2 m 3) bucket that could move 325 short tons (295 t) of material at a pass.
