Allied has combined performance, efficiency and reliability in their all-new boom-mounted Hy-Ram impact hammer to offer several design advantages over other hammer manufacturers — and we got an up-close look at them at the 2016 World of Concrete. The large, medium, small and mini-size Hy-Ram models are available in 8 different models ranging from working weights of 332 to 5,075 pounds and tool diameters of 1.77 to 5.91 inches.
One of the many features that contribute to the efficiency of the Allied Hy-Ram is the oil and gas operation. The Allied design of gas-assist using low pressure nitrogen improves the efficiency by reducing demand on the carrier’s hydraulic system. There is no dependency on hydraulic accumulators. The accumulators are merely used to eliminate hydraulic “spikes”. And, pressurized oil is always present at the bottom of the piston which prevents internal cavitation.
And there is much more to know. Be sure to watch the video from World of Concrete above and then head to the Allied website for more information.
