325  Sandvik is  introducing a line of new compact breakers that are aimed at carriers in  the 1.9-12.5tonne weight range. The new 275kg BR555, 370kg BR777 and  505kg BR999 are aimed at use by rental fleets and are designed to suit  an array of carriers. Features include a flange top-mount for adapter  installation, pivoting hose connecting block, reversible manifold, right  or left-hand hose connections, and the ability to accept a wide range  of oil flows and pressures. Each model comes with the firm's proven  constant blow energy (CBE) technology to ensure maximum impact energy  with every blow for maximum productivity and profitability. High  power-to-weight ratios are claimed as well as high productivity. The  moulded box-type housing eliminates the need for tie rods, reducing  maintenance times, and is said to minimise noise and vibration as well  as protecting the hammer internals. The units are said to offer  durability, reliability and serviceability and feature fewer parts for  easier and reduced maintenance. Increased life and reduced owning and  operating costs are also claimed.
