RELIABILITY REDEFINED

STRIKINGLY SMART

For more than five decades, GRUNDOMAT soil displacement hammers have stood for on-target underground pipe installation. Their exceptional longevity and high precision stem from the smart design, uncompromising quality and consistent development of our "moles". We never lose track of the requirements of users and the trends in pipeline construction. So that you can tackle your jobs faster and easier, we made the complex technology even more durable, reliable and easy to handle. That's what we call "simple & easy".

Discover the new Generation GRUNDOMAT

Reliability revisited

The new generation of GRUNDOMAT soil displacement hammers corresponds exactly to this principle. The optimised design combines all the benefits of previous series with new technical solutions. The distinctive characteristics of the GRUNDOMAT, such as the movable head for unbeatable power and pinpoint accuracy and the use of the highest quality materials for long construction site operations, make the GRUNDOMAT a reliable partner on your construction sites. The servo control for small machines is new and an intelligent internal design guarantees a long machine life. For the user this means the highest possible productivity and maximum efficiency for pipe installation.

SUSTAINED MAXIMUM PERFORMANCE

The design of the new GRUNDOMAT generation is the result of a careful development process focussing on user-friendliness. Combined with the proven reliability of our technology, we can give the user durable technology for trenchless pipe installation that is customised to their construction sites.
 
  • High penetration force and powerful thrust 

    also with maximum load thanks to specially hardened, corrosion-protected pistons.
  • Minimum air consumption at highest power 

    thanks to innovative piston technology and a sophisticated sealing system.
  • Optimum performance 

    through regular service with replacement of inexpensive slip belts and sealing rings.
  • Extremely long service life of chisel 

    with use of bearing bush.
  • Reliable and on-target thrust in two-stroke cycle 

    thanks to movable head with unique seal.
  • 01. Thecrowned or stepped head with two-stroke cycle displaces the soil in three steps with maximum precision and high running stability.
  • 02. The concentration of impact energy in thrust direction onto the sharp cutting edges guarantees a high penetration force.
  • 03. No front machine seal – enormous longevity and optimal energy transfer.
  • 04. The inner and outer chrome-plated housing, which is honed on the inside, is low-wear and low-maintenance, highly durable and ensures sustained maximum performance.
  • 05. The smooth outer housing has an easy-to-read wear indicator.
  • 06. Various mounting options for a variety of applications beyond the standard, e.g. immediate piping, pile foundations or driving out steel pipes.
ALL IN THE HEAD
Crowned or stepped head
The intelligent 2-stroke principle brings the impact energy to where it is needed. To overcome surface friction or peak resistance. This way the GRUNDOMAT soil displacement hammer achieves its almost legendary precision, even in difficult soils.

Stroke one

During the first stroke, the piston acts on the cutter so that the head cuts the borehole and crushes and removes any obstacles. The impact energy of the piston is concentrated on the cutter and the bore head.

Stroke two

In the second stroke, the drill head moves freely in the borehole and the full impact energy of the piston is transferred to the housing. The entire machine follows up, with a pipe attached as the case may be.

First live performance for GRUNDOMAT 75

The Bavarian town of Landsberg on Lech situated on the so-called romantic road and with its well preserved medieval town centre, is a major attraction for numerous tourists. The town, with 30.000 inhabitants, situated in the southwest of Bavaria is known as one of the sunniest towns in Germany. Also well preserved are a large number of churches and the baroque town. The list of architectural monuments is long: several towers in their pristine condition, such as the Towers of the Bayer Gate, the Mother Tower and the Smalt Tower, Town Wall and Town Gates. Bakers, Butchers, Painters, Tanners, Weavers etc. characterise the diverse craftworks and commercial enterprises of the town and are, even today, still vibrant in their wonderfully preserved houses and guest rooms within the town walls. Landsberg on Lech even has a small message for rock & roll fans: Elvis Presley was stationed here in this town, during his time as a soldier in Germany, where he also bought his very first guitar.
