The 26XPR high-performance pneumatic hammer for pipe ramming and pipe bursting applications from HammerHead Trenchless has a newly designed high-flow valve system that produces a more powerful impact. XPR technology is a modification of the Air Reverse, or AR, valve system standard on all HammerHead Trenchless pneumatic hammers larger than 7 inches. Both systems allow for the reverse function to be controlled above ground, greatly simplifying tool removal from pushing collets and burst heads. The 26-inch hammer has replaced the 24-inch AR model. It can install casing 24 to 84 inches in diameter and is effective in pneumatic pipe bursting applications of pipes 15 to 36 inches in diameter.
