Boasting 12 model sizes, a hydraulic breaker attachment line introduced by Chicago Pneumatic Construction Tools incorporates an enclosed-box design with elastic damping elements. Three heavy-duty models, with service weights ranging from 4,850 to 9,259 pounds and having 5.9- to 7.1-inch working-tool diameters, are suitable for excavators weighing from 26 to 75 metric tons. Four medium models, weighing between 1,213 and 3,527 pounds, are built for 9- to 34-metric-ton carriers. Five light models, with service weights from 209 to 827 pounds, are for 1.3- to 12-metric-ton carriers. Heavy and medium models feature the CP-Lube automatic lubrication system that attaches directly to the breaker.
