Companies such as Atlas Copco are working to minimize the risk of extended use of hand-held breakers by incorporating ergonomic features that minimize vibration.
These four models of hand-held hydraulic breakers feature a heavy handle suspended from a dampened pivot pin, decreasing vibration emissions without sacrificing efficiency or performance. Just two moving parts allow for minimal wear and service, while a closed-loop system keeps dirt and moisture out. Portable power packs or the hydraulic outlet on any carrier serve as the power source. The units weigh from 51 to 82 lbs. and offer impact ratings from 1,100 to 1,050 bpm.
