Atlas Copco Construction Equipment says its new HB 4100 heavy hydraulic breaker has a service weight of only 9,039 pounds, designed for carriers in the 88,185- to 154,324-pound weight class, but is as powerful as much heavier breakers. Improvements to the breaker include a guide system that makes the breaker more stable and resilient, a new cover plate for the retaining bars that offers more protection in the lower part of the breaker, and increased wear protection at the bottom of the case. The breaker is suitable for secondary and primary rock breaking.
