Información general

    En comparación otros equipos de hincado, el Martillo TERRA-HAMMER casi siempre es el más veloz y el más potente de su categoría.

    Los émbolos percutores extremadamente pesados generan una fuerza de empuje extraordinaria. El peso del émbolo constituye hasta el 60 % del peso total de la màaquina.
    Los equipos de hicado, martinetes TERRA-Rammen son cortos. SEgún el modelo, los eqipos TERRA son entre 1.0 y 1.5 m más cortos que otras máquinas convencionales - y esto, ofreciendo mayor potencia.

Heavy main piston – 3 years of warranty (industry leading)

    The heavy main pistons (strikers) produce the unusual high impact and ramming energy. The main piston weighs up to 60 % of the machine. Even the largest main pistons with a weight of 1.5 tonnes are produced from one single piece. Therefore there are no critical joints. Due to the heavy main piston the ram has an enormous ramming force. The impulse is transfered where it is needed – in the head! This is possible through the hollow head design. TERRA offers a warranty of 3 years for all main pistons.

Smart hollow head design

    The TERRA-HAMMER is not afraid of any comparison to conventional rams due to TERRA's tremendous power and enormous speed. If you compare the main pistons of TERRA to other conventional main pistons, you can see, that the TERRA main pistons are longer. The ram itselfe remains shorter but stronger at the same time. This is only possible because TERRA has invented the hollow head design. The impulse is transfered where it is needed – in the head. Thanks to the acceleration ports in the main housing the main piston can be moved with low air consumption.

Horizontal application

    Steel pipes up to Ø 3'000 mm are rammed horizontally through the ground. The ram sits behind the steel pipe. Depending on ground conditions and steel pipe diameter drive lengths up to 120 m are possible.

Pipe roofing

    The TERRA-ram can also be used in tunnel constructions. It rams several steel pipes parallel to produce a roof.

HDD assist

    When pulling in long steel pipes with HDD drill rigs, the TERRA ram gives dynamic assistance at the rear of the steel pipe. This leads to higher productivity and longer drilling lengths.

HDD casing

    When a HDD drill takes several months there is the risk, that the entry of the drill collapses. In such a case it is useful to ram a steel pipe 30 ‐ 50 m (100 ft) as a protection pipe into the ground.

HDD rescue

    When a HDD drill is jammed, the TERRA ram helps to rescue the rods.

Ramming diagram

    The size selection of the TERRA‐Ram depends on the diameter of the steel pipe, also the total length of the ramming job. The chart below can be used to select the most suitable size of TERRA‐Ram.


    This chart can be used if ramming through medium strength ground. When ramming through much softer or harder ground a smaller or larger TERRA-Ram may be required. The above diagram is valid only for medium strength ground. TERRA cannot be held liable for any unsuccessful ramming job which was assumed possible based on the chart above, it is offered as a guide only.
