Epiroc, Commerce City, Colorado, has announced its new solid body (SB) breaker range. The new SB 302 and SB 452 Tunnel versions provide application-specific modifications designed to extend equipment lifetime and reduce overall operating costs in underground applications.

The advanced Tunnel versions feature a new piston in stainless steel designed to extend piston life, while bushing seat wear is minimized by a press-fit, one-piece bushing locked by an additional pin, Epiroc says. An exchangeable wear plate protects the hammer body and durability is enhanced by heavy duty retainer bars and a locking pin.

The special tunneling tool with a collar supporting a front shield and dust cover is manufactured to minimize the dust intake when working on overhead areas. Two restrictors are available that are made to enable the performance of the hydraulic breaker to be adjusted for either traditional scaling operations or for more challenging rock breaking jobs.

Together these new features add up to less wear, extended lifetime and lower overall operating costs in scaling, tunneling and underground mining applications, Epiroc says.

The new Tunnel versions are suitable for excavators in the weight class from 4.5 to 13 tons (10,000 to 28,500 pounds) and standard underground scalers. Service weights are 690 pounds for the SB 302 and 990 pounds for the SB 452.
