Description
The Atlas Copco BBC Series Pusher Leg is a pneumatic pusher leg for Atlas Copco BBC-series stoper drills (BBC 16W, BBC 34W) in underground mine and tunnel work. It replaces operator manual feed force with compressed-air thrust against the rock face, freeing the operator to control drill orientation. Mining and tunneling crews specify it for face drilling, rock-bolt holes, and overhead anchor work where the BBC drill alone is too heavy to support.
- Pneumatic pusher leg attachment for Atlas Copco BBC-series stoper rock drills (BBC 16W, BBC 34W) in underground mine and tunnel work.
- Replaces operator manual feed force with compressed-air thrust against the rock face, freeing the operator to control drill orientation and bit advance.
- Six part-number configurations: BMK-62S, ALF71, ALF71-1, ALF72D, ALF72D-1, and BMT 51 across current and legacy Atlas Copco production generations.
- Different part numbers reflect different production generations; confirm the part number that matches existing service inventory when specifying a replacement.
- Pneumatic feed cylinder runs on the standard Atlas Copco pusher-leg air connection, no separate hydraulic or electric power source required.
- Built for face drilling, rock-bolt holes, and overhead anchor drilling at the working face in underground hard-rock mining and tunneling.
- Crowder Supply stocks the Atlas Copco pusher-leg range, BBC 16W and BBC 34W stoper drills, and replacement parts for both drill and leg.
- Atlas Copco is a Swedish manufacturer of mining and construction tools with one of the longest pneumatic rock-drilling pedigrees in the industry.
