January 22, 2018 – LAKE MILLS, Wisc. – HammerHead Trenchless, a Charles Machine Works Company, 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, a 26-inch hammer, is the first model to be equipped with the performance-enhancing XPR technology. It 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.
The hallmark of all HammerHead Trenchless 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.
HammerHead Trenchless produces 11 models of pneumatic hammers ranging from 4 to 34 inches, capable of ramming pipe diameters ranging from 4 to 180 inches or bursting pipe diameters from 4 to 36 inches.
While the 26XPR is the first model of the new XPR series, HammerHead Trenchless plans to expand the series in the future by equipping other sizes of hammer with the high-performance technology.
The 26XPR hammer is available from HammerHead Trenchless or from authorized dealers, worldwide. Authorized dealers can be found on the web at www.hammerheadtrenchless.com or by calling 800.331.6653. (International: + [1] 920.648.4848).

GSSI, the world’s leading manufacturer of ground penetrating radar (GPR) equipment, announces the addition of a new drill hole feature to the StructureScan™ Mini XT – the newest generation of GSSI’s popular all-in-one concrete inspection GPR system. The drill hole feature is a 3D data processing detection algorithm. The algorithm evaluates a user chosen cylindrical area that represents a potential or planned coring location. Scanning for all potential targets within the cylindrical area, the drill hole feature looks for targets that may interfere with a proposed coring location.
Available only within the StructureScan Mini XT user interface, the drill hole indicator is designed for concrete coring applications. In complicated slab situations, the drill hole feature can help users determine the safest location for coring concrete. However, this feature is not a substitute for careful analysis by a trained operator, and GSSI does not recommend that the user depend solely on this algorithm for drill hole interpretation.
Operators should receive special training prior to using this new aid. During training, customers can select areas that they believe are safe for coring while the feature is turned off, and turn the feature on to double check and confirm the initial mark outs.
The new drill hole feature will work with all StructureScan Mini XT’s already in the field, and only requires a software update of the system. New units will come with this user interface pre-installed.
About GSSI
Geophysical Survey Systems, Inc. is the world leader in the development, manufacture, and sale of ground penetrating radar (GPR) equipment, primarily for the concrete inspection, utility mapping and locating, road and bridge deck evaluation, geophysics, and archaeology markets. Our equipment is used all over the world to explore the subsurface of the earth and to inspect infrastructure systems non-destructively. GSSI created the first commercial GPR system nearly 50 years ago and continues to provide the widest range and highest quality GPR equipment available today.
