Drills
In 1952, Bucyrus introduced the first commercially accepted
electric Rotary Blasthole Drill, changing mining
productivity forever. Bucyrus has continued to improve upon
the technology and design to offer the most reliable,
productive and cost effective means of drilling in mining
operations. A few noteworthy refinements include programmed
drill control, rack and pinion pull-down and hydrostatic
propel drives. Bucyrus continues to be the market leader of
large blasthole drills in the world.
