The Grundomat Adventage |
|
Grundomat pneumatic piercing tools have been providing accurate
horizontal bores beneath roads, railways, and landscaping across North
America and around the world for nearly 40 years. Water, gas, sewer and
electrical industries have all benefited from this work horse of
trenchless technology. Minimal operating space is required and the tool
serves as a complement, and in many situations an economical alternative
to, larger, more expensive directional drilling equipment. |

|
How It Works |
|
Compressed air repeatedly propels the
piston against the rear of the chisel head assembly. This first
compresses the pre-tensioned steel spring which forces the chisel head
assembly forward independently of the main casing to provide a pilot
bore. Then, the same continuous force thrusts the main casing ahead.
With decades of proven performance, the Grundomat’s patented
stepped-cone head consistently provides accurate results. |
