Pit launched machine TERRA MINI-JET MJ 1600 - Strong and compact design

    The compact HDD system TERRA MINI-JET MJ 1600 is one of the most powerful and most productive compact HDD systems, which is available worldwide. Powered by a proven 33 HP strong KUBOTA Diesel engine the MJ 1600 offers up to 6 tons of thrust and pullback force, 1.600 Nm of torque and a maximum spindle speed of 125 rpm. With its 52 ltr/min high pressure pump you can drill up to 50 m and backream up to 300 mm (depending on ground).

Compact design

    Due to its compact design the MJ 1600 can work out of a pit with dimensions of only 1.3 m x 1.3 m. The small footprint and the reduced noise level at the operator’s ear make the TERRA MINI-JET MJ 1600 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.

Double cylinder drive (patented)

    Thrust and backreaming of the driving saddle happens by a direct double cylinder drive. This is free of losses, strong and reliable. This new idea from TERRA allows maximum drilling and backreaming forces. The double cylinder operates in both directions with 6 tons.

Clear control panel

    All components of the MINI-JET are clearly arranged. The integrated electrical control of the the drilling volume takes place by the control panel. For the locating monitor there is a 12 voltage connection. The launching cradle is equipped with a grounding stake and an electrical strike alarm. The automatic drilling and backreaming system adjust the speed within milliseconds to the ground. With this drilling assistant system even difficult drills can be done.
