Top 100: Self-Protecting Breakers

September 28, 2010

Atlas CopcoAtlas Copco's complete line of 15 hydraulic breakers spans impact classes from 200 to 15,000 foot-pounds. The units are separated into three categories: the light Penta Breaker (PB), Medium Breaker (MB), and Heavy Breaker (HB) Series. MB and HB models feature the ContiLube II self-contained automatic lubrication system, AutoControl to protect the hammer from dry firing, and DustProtector II for extreme-duty applications. StartSelect controls how the hammer engages the material to be broken, according to the operating conditions. Replacing the company's Street hammer series, PB breakers for backhoe-loaders, skid-steer loaders and other compact equipment have fewer parts and a pentagonal housing design for extra strength. On all models, elastic elements between the percussion mechanism and guide system provide full acoustic insulation to reduce noise. Estimated list price: $249,000 for HB7000; $14,830 for PB420.
