EPIROC USA, Commerce City, Colo, introduces the SB 302 and SB 452 Tunnel versions of its SB series of hydraulic breakers for use in rock quarrying.
Application-specific modifications that extend equipment lifetime and reduce overall operating include a new piston in stainless steel, while bushing seat wear is minimized by a press-fit, one-piece bushing locked by an additional pin. 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 robust front shield and dust cover minimizes the dust intake when working on overhead areas. Two restrictors are available which enable the performance of the hydraulic breaker to be adjusted for either traditional scaling operations or for more challenging work.
The new Tunnel versions are suitable for excavators in the weight class from 4.5-13 tons (10,000-28,500 lbs) and standard underground scalers. Service weights are 315 kg (690 lbs) for the SB 302 and 450 kg (990 lbs) for the SB 452.
