All-new Hy-Ram hydraulic impact hammer
Allied Construction Products’ all-new Hy-Ram HR Series hydraulic impact hammer has “streetwise” attributes like an oil and gas operation that increases efficiency, a longer piston stroke for higher impact power and an auto-stop system to prevent “blank firing.”
The concept of the high performance boom-mounted hydraulic hammer was pioneered by Allied Construction Products.
With continuous improvements over the years, the Allied Hy-Ram still uses the same simple, proven design that first gained industry-wide acceptance for thehydraulic hammer concept.
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, the company stated.
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". Pressurized oil is always present at the bottom of the piston which prevents internal cavitation.
Another feature that contributes to the reliability of the Allied Hy-Ram is the long-stroke design which minimizes recoil, reduces vibration and eliminates mechanical springs.
The Allied medium and large Hy-Rams also have an automatic Auto-Stop feature that prevents blank-firing once the demolition tool has penetrated through the material being broken and downpressure is no longer applied.
The Allied Hy-Rams also feature a durable housing design that suspends the internal working body inside a full-box enclosure to protect the hammer, reduce noise and minimize vibration and wear to the carrier. The durable housing design is enclosed at the bottom and incorporates a heavy-duty Hardox rock claw.
Hy-Rams are also available with an optional AutoLube mounted on the hammer housing. This is an automatic lubrication system that dispenses lubricant by the hammer’s vibration. The AutoLube uses a high-grade chisel paste in handy replaceable cartridges
The Hy-Ram, which operates off of the carrier's hydraulic system, requires an installation kit in order to be mounted on the backhoe/loader, excavator or similar carrier. Allied offers over 2,500 installation kits to fit virtually every make and model carrier.
The large, medium, small and mini-size Hy-Ram models are available in 12 different models ranging from working weights of 265 to 8,375 pounds and tool diameters of 1.77 to 6.88 inches.
