HammerHead Introduces XRP High-Performance Pneumatic Hammers

HammerHead Trenchless released its new XPR series of pneumatic hammers for pipe ramming and pipe bursting applications. XPR features a newly designed high-flow valve system that enhances its impact. The first model to utilize this new technology, the 26XPR is the most powerful pneumatic hammer in its class.

XPR technology is a modification of the patented Air Reverse (AR) valve system that is standard on all HammerHead pneumatic hammers larger than seven inches. Both systems allow for the reverse function to be controlled above ground, greatly simplifying tool removal from pushing collets and burst heads, saving valuable time on the job. The 26XPR has replaced the 24-inch AR model in the HammerHead line of pneumatic hammers.

“While our 24-inch hammer has proven to be durable and effective, we identified a need for a more versatile and higher performing tool,” said product manager, Josh Hood. “By designing a system that maximizes the air flow, we were able to increase forward horsepower, while maintaining the highly desired functionality of the Air Reverse feature. We chose the 26XPR to be the first model to utilize the new technology to better bridge the gap between our 20- and 34-inch AR models.”

The 26XPR is capable of installing casing 24 to 84 inches in diameter and is suitable for use in drainage culverts, pipeline work and HDD assist methods, such as wash over casing installations, pipe assist or pipe extraction, and guided pilot bore ramming. It is also effective in pneumatic pipe bursting applications of pipes ranging from 15 to 36 inches in diameter.

Other sizes of hammer will be equipped with XRP technology in the future.

The hallmark of all HammerHead pneumatic hammers, including the new 26XPR, is easy serviceability to minimize costly downtime due to tool maintenance. It features HammerHead’s patented clamped rear anvil and tail bolt designs; one-piece body and striker; and high-temperature, replaceable wear rings.
