TT Technologies
Grundomat is constructed from durable hardened alloy steel and reliable machined components for maximum power and precision. Grundomat tools are also equipped with an advanced reversing system, as well as, an in-line lubrication system. Basic and deluxe packages are available with the Grundomat. Especially suitable for economical last mile installation, the Grundomat’s reciprocating stepped-cone chisel-head ensures high impact accuracy. The chisel-head action of the Grundomat tool is unique because it hammers away at solid obstacles. This two-stroke action means that the piston's impact is concentrated on the reciprocating tool head for optimum boring performance. The Grundomat is available in 16 models ranging from 1 ¾ to 7 inches in diameter, for horizontal boring distances from 50 feet to 150 feet. 800.533.2078, tttechnologies.com

HammerHead Trenchless Equipment

The Catamount line of piercing tools offers a reciprocating head tool that is easy to start, regardless of air pressure level. The pneumatic piercing tool head is effective in both hard and soft soil conditions. The Catamount tool line is currently available in 2.5-, 3- 3.50- and 4.38-inch diameter tools. The head is driven by air that resets the head, eliminating the need for mechanical springs, which are a common source of failure in trenchless tool designs. The design takes full advantage of reciprocating head technology by increasing production rates in all soil types and also reduces tool swim at any operating pressure. A patented quarter-turn reverse feature pneumatically locks the tool into forward or reverse gear, preventing accidental direction change during the bore. The valve whip is designed to be flexible, preventing tool binding if a bore collapse occurs. Designed to eliminate the introduction of debris into the tool body, a patented debris free tailcone increases overall production and tool life. 800.331.6653, hammerheadtrenchlesss.com
