The true value of the GRUNDORAM rammers

...becomes obvious when looking at the ramming capacity, which depends on soil quality, pipe diameter and installation length. Casing friction and front resistance have to be overcome. The TT ramming machines have sufficient power reserves to guarantee high ramming capacity.

That is why we attach great importance to the impact capacity, reliability, robustness and longevity. Look at the check list and find out, whether cheap products or plagiatisms fulfil the same preconditions required for all applications. Also be beware of cheap repairs, which are carried out without the original spare parts.
