Stanley BR45 Hydraulic Class Breakers have a Rugged, Lightweight and Powerful construction which make them ideal for use in the 35-65 pound class (2-6" Concrete). Designed for light- to medium-duty operation, they excel at curb and sidewalk demolition, asphalt cutting, and are popular for ground rod driving with electric utilities. The Stanley Easi RideTM foot, offered on the BR45 absorbs and controls tool-bit bounce, greatly reducing operator fatigue. Available with Standard T-Handles or Spring Isolated, Anti-Vibration Handles (BR45S) reduce operator fatigue, literally allowing the breaker to float in the user�s hands. Built in Handle Stops on anti-vibration handle model (BR45S) allow operator to apply full body weight in tough applications. Feathering On/Off Valve allows the operator to control the output energy of the tool through the full range from 0 to 1,800 blows per minute, making startup and initial tool placement easy. Diaphragm-Type Accumulator design provides for ease of maintenance and extended service life of the tool. Operate at a 2000 psi input pressure, 8 gpm outflow with a maximum back pressure of 250 psi (17 bar) on open-center systems. Complete Line of Steels for breaking, cutting, or driving are available from SafetyTest. Note: All models ship with hose whips.
