TERRA-HAMMER TR 220

Steel pipes up to ø 600 mm (ø 24")

Allgemeine Infos

    The TR 220 only requires 7 m3/min which makes the TR 220 one of the most efficient rams in its class. It requires 40 % less air consumption than competitors rams. Our Swiss engineers have designed a compact machine with a very high impact main piston.


  1. For steel pipe diameter: 150 – 400mm (6" - 16")
  2. Ramming force: 155 tonnes (170 US tonnes)
  3. Air requirement: 4 m3/min (140 cfm)
  4. Length: 0.90 m (3 ft)
