HDI Lucas announced it had received two new TRACTO-TECHNIK GRUNDORAM dynamic ramming hammers, with the tools on their way to site for the installation of 52 inch (1,320 mm) and 16 inch (406 mm) casings for two rock crossings.
The pneumatically driven GRUNDORAM ramming machines provide thrust forces up to 40,000 kN and are applicable in all kinds of soil types, with the exception of muddy areas, swamps and compact, non-displaceable soil for a variety of applications.
The most common GRUNDORAM application is the horizontal installation of steel pipes up to nominal diameter 4,000 mm underneath streets, railway tracks and rivers up to 80 m length without pressing abutments, while the horizontal rammers can also be used for vertical applications to support horizontal directional drilling (HDD) and dynamic pipe renewal.
HDI Lucas is a subsidiary of Spiecapag Australia and is well known for its expertise in the HDD field.
