THE HDD MULTI-TALENT GRUNDODRILLL 4X CONVINCES IN ENGLAND
The compact HDD small drilling rig GRUNDODRILL 4X was able to prove its versatility in various construction projects in Great Britain. The applications ranged from the installation of a fresh water pipe to supply free-ranging cattle in a protected forest area to the installation of power cables for the operation of an innovative solar system on a private property.
In addition, data cables were installed in two construction projects: On the one hand as a connection of two office buildings of a car dealer in a heavily frequented industrial area and on the other hand at a crossing under a country road. All four applications had in common the particular local conditions, such as cramped and sometimes difficult to access space or the requirement to damage the existing surfaces as little as possible.
Exactly the conditions for which the trenchless HDD technology in detail and the GRUNDODRILL 4X in particular are predestined due to its manoeuvrability and its low weight, and thus scored points all along the line.
