BH-3 Blockholer Secondary Breaker

Rugged and reliable, the BH-3 is designed to eliminate ore flow blockages and release trapped reserves in draw points and beyond draw point brows without endangering mine workers. Integrated Radio-Remote Control (RRC) allows tramming, drilling and blasting operations to be conducted from safe distances.

BH-3

The MacLean Advantage:

• Oversize is fragmented at source, minimizing draw point damage and ore flow
• Productivity improvements by elimination of non-productive boulder re-handling
• Boom configuration enables multiple boulders to be drilled from one set up
• With RRC system, can drill and charge hang ups and operator never exposed to the risks of rock fall
• Provides auxiliary drilling capability for service holes and rock bolting

 

Features:

• Fully self-contained drilling system; no air or water services necessary
• Optional radio and video system designed for underground environment
• Hydraulic rock drilling
• Heavy duty frame construction
• Four wheel drive carrier
• Reliable, proven power train components
• High powered electronically controlled Caterpillar™ engine option

 

Applications:

• Any underground mine where bulk mining activities generate boulders too large to move, carry, drop through grizzlies or dump into crushers.
• Most effective where multiple draw points allow ore extraction to continue while block hole operations are conducted.
