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. This machine featured a 220-yard bucket on a 450-foot boom and weighed 14,500 tons.
The buckets itself is reinforced by 5 to 10 mm steel plates to prevent deformation and wear-and-tear. [6] A unique design choice for the Type Es 3750 is the presence of two excavator's control cockpit, each spraying outwards on the left and right side of the machine.
For example, Caterpillar's smallest mini-excavator weighs 2,060 pounds (930 kg) and has 13 hp; [8] their largest model is the largest excavator available (developed and produced by the Orenstein & Koppel, Germany, until the takeover 2011 by Caterpillar, named »RH400«), the CAT 6090, which weighs in excess of 2,160,510 pounds (979,990 kg), has ...
The Big Muskie was a model 4250-W dragline and was the only one ever built by the Bucyrus-Erie company. [1] With a 220-cubic-yard (170 m 3) bucket, it was the largest single-bucket digging machine ever created and one of the world's largest mobile earth-moving machines alongside the Illinois-based Marion 6360 stripping shovel called The Captain and the German bucket wheel excavators of the ...
Bucket chain excavator, human for size comparison. A bucket chain excavator (BCE) is a piece of heavy equipment used in surface mining and dredging. BCEs use buckets on a revolving chain to remove large quantities of material. They are similar to bucket-wheel excavators and trenchers. Bucket chain excavators remove material from below their ...
Bagger 288 (Excavator 288), previously known as the MAN TAKRAF RB288 [2] built by the German company Krupp for the energy and mining firm Rheinbraun, is a bucket-wheel excavator or mobile strip mining machine. When its construction was completed in 1978, Bagger 288 superseded Big Muskie as the heaviest land vehicle in the world, at 13,500 tons. [3]
