Allied m-Series

The two new hydraulic-impact-hammer models in the Rammer Allied m-Series use a new modular-design concept, which incorporates three major components — the housing module, impact module and tool module. Benefits of the new design, says the manufacturer, include simplified maintenance and the latitude to overhaul the modules separately. Hammer design also is aimed at promoting optimal performance by allowing impact-energy adjustment to match working conditions, while the constant-blow-energy feature, says Allied, ensures that all blows are delivered at full power. A high power-to-weight ratio combines with a heavy piston to deliver more impact energy, says the company, and the Ramlube system continuously greases both bushings in all conditions. Hydraulic-flow requirements are 48 gpm for the model m14 and 58 gpm for the m18. Both require a pressure of 2,321 psi.
