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.
Steel pipes up to ø 1,000 mm
840 tons of impact force. Only 1.75 meters in length.
The TERRA-HAMMER TR 360 combines maximum performance with impressive efficiency. With an impact force of 840 t, it is one of the most powerful steel pipe rammers on the market. At the same time, it is extremely compact with a length of only 1.75 m and, thanks to its acceleration ports, consumes only 12 m3/min at 7 bar. It is therefore shorter and requires significantly less air than comparable rammers of this size.
The TR 360 allows for the installation of steel pipes up to ø 1,000 mm precisely, economically, and reliably. The steel pipes are driven horizontally into the ground in 6 m or 12 m segments. The rammer positioned behind the steel pipe ensures continuous advancement. Depending on soil conditions and pipe dimensions, installation lengths of over 80 m are achievable. This method is particularly suitable for trenchless crossings of traffic routes, bodies of water, and other obstacles.

For pipe diameters up to ø 800 mm, plug-in ramming rings are used. These can be flexibly combined with the next larger ramming ring in the TERRA plug-in system.
For pipe diameters from ø 800 mm upwards, specially developed ramming plates are available. Thanks to their precisely matched outer cone, they can be inserted directly into the steel pipe being driven, allowing for simple and efficient power transmission.

For a safe starting process, the TERRA rammer is secured using specially adapted mounting accessories clamped to the steel pipe. The tension chain provides a reliable connection between the steel pipe and the tensioning strap, ensuring secure power transmission during the driving process.

Thanks to the innovative acceleration ports in the impact piston, the hammer requires up to 40% less compressed air than comparable systems. With an air volume of just 12 m³/min at 7 bar it operates extremely efficiently. Depending on site requirements, it can be operated flexibly with one or two compressors . The internal airflow has been continuously developed, optimized, and perfected over decades. The result is a highly efficient system with maximum impact performance and minimal energy consumption.

With TERRA hammers, steel pipe segments with lengths of 6 m or 12 m can be driven in safely and efficiently.
For a constant and optimal oil supplya lubricator with 10 l capacity is available. This enables reliable lubrication of the hammer throughout the entire operation and contributes to maximizing the machine's performance and service life. For optimal hammer operation, a biodegradable, synthetic HD oil with high viscosity is used.
Thanks to its compact design, the TR 360 can also vertical and is therefore ideally suited for applications in specialist civil engineering, pipe jacking, and foundation work. It stands for reliable performance, high efficiency, and precise results – even under demanding operating conditions. The steel pipes serve as foundations for utility poles, as foundation piles, as bollards for port facilities, or as piers for jetties.
Your advantages
840 tons of impact force
Steel pipes up to ø 1,000 mm can be installed precisely, economically, and reliably using trenchless methods. TERRA offers ramming plates and ramming rings as a plug-in system for this purpose.
Compact design (1.75 m)
The TR 360 is over 0.6 m shorter than comparable rammers. This is only possible due to the patented hollow head design.
3-year warranty on the percussion piston
TERRA offers a 3-year warranty on the percussion piston. It accounts for over 50% of the total weight and generates extremely high impact forces due to its significant mass.
Vertical operation possible
The TR 360 can be used both horizontally and vertically. The steel pipes serve as foundations for utility poles, foundation piles, bollards for port facilities, or piers for jetties.
