The TERRA-PIT DJ 18 is the most powerful and productive HDD pit launch machine that is available on the world market. Powered by a proven 75 HP HATZ Diesel engine the DJ 18 PIT offers up to 8 tons of thrust and pullback force and 3.000 Nm of torque. With its 95 ltr/min of drilling volume and a maximum drilling pressure of 70 bar you can backream up to 420 mm over lengths of 150 (depending on ground conditions).
The TERRA-PIT DJ 18 can be pit or surface launched. This HDD system has a modular design. Its main components are the pit frame, the hydraulic power pack and the mixing+pumping station.
With its 2 separated hydraulic circuits for thrust and rotation, the DJ 18 PIT can operate simultaneously at maximum torque and maximum thrust or pullback force. The hydro-chain-drive has the highest efficiency rate, low wear and is dirt resistant. Due to the movable break-apart-system.
