HammerHead Trenchless has released the first model of its new XPR series of high-performance pneumatic hammers for pipe ramming and pipe bursting applications. The XPR series features a newly designed high-flow valve system that produces a more powerful impact. The first model to utilize this new technology, the 26XPR, is the most powerful pneumatic hammer in its class.
The XPR technology is a modification of the patented Air Reverse (AR) valve system standard on all HammerHead pneumatic hammers larger than 7 inches (180 mm). 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 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.
