THE PIONEER


THE MAINSPRING

On target every time

PISTON SEAL, SLIDE BELTS & CUTTING HEAD SEAL

Guarantee great efficiency and low air consumption while preventing dirt from getting inside and causing power to be lost.

STROKE ONE

Stroke one applies impact to the cutter bit with the piston, thus forcing the head to generate the bore hole and eliminate obstacles. The impact energy is concentrated on the cutter bit and the bore head.

STROKE TWO

During the second stroke, the bore head moves freely in the bore hole and the piston aims the impact right up to the casing. The impact power of the piston is concentrated on the casing, the complete machine (with the pipe attached) moves up from behind.
The two-stroke principle helps to overcome peak resistance and coat friction so the highest possible directional stability of the GRUNDOMAT is achieved.

Technical data

Fast and safe installation of gas service lines in tough conditions

While it is often assumed that individual methods of trenchless installation tools and technology compete for projects, that’s not always the case. On a recent gas main and service replacement project, contractor Underground Construction Co. Inc. headquartered in Benicia, CA, was able to effectively employ the soils displacement method and horizontal directional drilling for installing approx. 3 kilometres of gas mains and about 120 gas service connections. The project was completed at a golf course retirement community in Sun City West, Arizona. Find out more
