One of the most productive 9 tonnes HDD drill rigs in its class - the DJ 20

    Powered by a proven 75 HP strong HATZ Diesel engine (Stage 5) the TERRA-JET DJ 20 offers up to 9 tons of thrust and pullback force, 2.840 Nm of torque and a maximum spindle speed of 228 rpm. The small footprint and the reduced noise level at the operator’s ear make the TERRA-JET DJ 20 user friendly and sustainable. The fast set up time and the increased movability helps you to operate your machine also in urban areas or family‘s backyard. It is the perfect machine to complete your HDD drill rig fleet in the 8-10 tonnes class.

Superb operators cabin

    Intelligent features like the thrust boring, the carve mode and the cruise control make drilling and steering very easy, also in hard ground conditions. The operator sits on a superb cabin. The cabin can be turned in 22.5 degrees steps from the driving position to the 90 degrees position. All control components will turn with the cabin. The operator chooses his optimum position.

Rack and Pinion Drive

    THRUST and PULLBACK of the driving saddle are carried out via Rack and Pinion Drive. This is reliable and powerful. Three hydraulic motors with gear boxes move the driving saddle. In the quick gear they reach 17 m/min (56 ft/min). The two rotation motors of the driving saddle create the high torque.

Servis dostu

    S-Series son derece kolay ve güvenilir bir şekilde servise uygun olarak dizayn edilmiştir. Servis amacı ile bütün hidrolik bileşenlerine kolayca erişilebilmektedir. Motor kapağı takviyeli fiberglastan (GRP) yapılmış olup, gazlı desteklerle 45° kaldırılabilmektedir. Ayrıca tüm parçalara en rahat şekilde erişim için tamamen kaldırılabilmektedir. Elektrik bileşenlerine kolay erişim amacı ile kabinin içindeki merkezi kontrol panelinin içine yerleştirilmiştir.

Break-apart System

    The break-apart system allows the hydraulic break-apart of the drill rod threads. The break-apart torque of 5’100 Nm (3800 ft.lbs) is nearly twice as high as the torque of the driving saddle. The clamping force is 100 kN (10 tons, 22'000 lbs). This guaranties that the drill rod threads can be always opened reliably.
