Versatile for fiber optics and small conduits.

‍

The TERRA piercing tool ø 68 mm combines compact dimensions with high precision and reliable performance. It is particularly well-suited for fiber optic installations and is available in both short and long versions. The quick-reverse feature allows for flexible and easy operation on the job site.

The ø 68 mm soil displacement hammer is one of TERRA's bestsellers. It is short, compact, and lightweight, yet despite its handy design, it impresses with high impact energy and powerful performance.

The TERRA lubricator version S ensures reliable and consistent lubrication of the machine during operation. The stepless control of the oil flow rate allows for precise adjustment of the oil quantity to suit specific operating conditions. Thanks to the integrated start-stop valve, the oil supply can be easily and quickly interrupted or reactivated. The robust design makes the TERRA lubricator version S particularly durable and ideal for demanding use on the construction site. A simple, reliable, and efficient solution for the continuous lubrication of your machine.

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 simultaneously protecting the machine against rust and internal icing. The oil is available in practical 5-liter canisters and is ideal for professional construction site use.

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.

TERRA's locatable head adapters allow for precise tracking exactly where it's needed—in the head of the soil displacement hammer. The probe is inserted into the side of the adapter and reliably protected from vibrations by robust cushioning buffers. Operating at a frequency of 44 kHz, the probe enables the soil displacement hammer to be tracked at depths of up to approximately 4 meters. This ensures the position of the hammer can be reliably determined at all times, without the need for a tracking unit at the rear end of the hose. Precise tracking. Robust protection. Directly in the hammer head.

TERRA expander sleeves allow you to use the same soil displacement hammer to create bores significantly larger than the diameter of the hammer itself. This enables the installation of larger pipes without needing to switch to a larger soil displacement hammer. The process is carried out in two stages: first, a pilot bore is created using the TERRA soil displacement hammer. Then, the expander sleeve is attached, and the existing displacement channel is enlarged to the desired diameter. As the soil displacement hammer moves forward, it pulls the expander sleeve along securely, enlarging the bore efficiently and in a controlled manner.

For the ø 68 mm soil displacement hammer, TERRA offers an expander sleeve up to 80 mm (for PE pipes <63 mm).
