TERRA AG develops and manufactures machinery for trenchless pipe installation. Since 1975, our name has been synonymous with Swiss precision, durable technology and reliable service.
for PE pipes < ø 160 mm
Maximum performance for major tasks.
The TERRA-HAMMER T 190 F was developed for particularly demanding trenchless installation projects. With its high impact force, it enables fast and reliable pipe installation and is ideal for laying PE pipes up to ø 160 mm. Furthermore, it can also be used for ramming steel pipes. The remote control provides maximum flexibility and control.
The TERRA soil displacement hammer impresses with its extremely high impact power. The momentum of the striker is precisely transferred to the robust housing and converted directly into forward thrust. This creates high penetration power, enabling efficient and reliable advancement even in challenging soil conditions. The direct power transmission ensures high performance in a compact design, making the TERRA soil displacement hammer a powerful tool for trenchless installation work.
The TERRA lubricator unit Version F was specially developed for lubricating TERRA soil displacement hammers with remote reversing. It enables reliable lubrication and convenient control of the soil displacement hammer directly from the lubricator unit.
Reversing between forward and reverse travel is performed via the integrated reversing valve. Thanks to this remote reversing feature, the direction of the soil displacement hammer can be easily controlled from the lubricator unit.
TERRA soil displacement hammer oil is a high-quality, biodegradable special oil developed specifically for use with TERRA soil displacement hammers. It ensures reliable lubrication while protecting the machine against rust and internal icing. The oil is available in practical 5-liter canisters and is ideal for professional use on construction sites.
TERRA cable clamps enable safe and reliable direct pipe installation with the TERRA soil displacement hammer. The PE pipe is connected directly to the soil displacement hammer and pulled into the ground immediately during the boring process. The steel cable is attached to the soil displacement hammer and securely connected to the PE pipe via the cable clamp. This ensures that the pulling force is reliably transferred to the pipe, maintaining a stable connection throughout the entire boring process.
Your advantages
Fast and precise pipe installation
With its combination head featuring steps and longitudinal grooves, the TERRA-HAMMER works quickly and accurately. This reduces installation time and increases productivity.
Ramming of steel pipes
The TERRA piercing tool can ram steel pipes without any conversion. TERRA offers ramming rings in various sizes for this purpose.
Reversing at the lubricator
With the remote reversing feature, the ø 105 – 210 mm soil displacement hammers can be conveniently reversed pneumatically via the lubricator.
3-year warranty on the striker
TERRA offers a 3-year warranty on its strikers. This is unique worldwide.
