TERRA MINI-JET MJLV 1600

HDD class: 4 - 6 tons, pit launch machine

Pit launched drilling with the MINI-JET LV 1600

    The MINI-JET MJLV 1400 is a strong pit launched machine with 6 tonnes (13'200 lbs) of pullback and thrust force and 1’600 Nm (1200 ft.lbs) of torque. With this machine all the advantages of pit launched machines are united in one machine. It was developed especially for the Swiss Alps, where you do not have a lot of space, no flat fields and difficult underground. TERRA has patented a special double cylinder drive, where two cylinders move the driving saddle for- and backwards with no loss of power. This is unique worldwide. With the MINI-JET LV you can drill 120 m and backream up to Ø 300 mm (12”).

    The MINI-JET LV is the long version of the smaller MINI-JET. The special drill rods are 1.5 m (100 ft) long and have a bending radius of 25 m (75 ft).

    The MINI-JET LV can be adapted with rock drilling tools for hard ground conditions.

    The Swiss Engineers have once more proven their strength in high-quality engineering.

Option: rubber crawler

    With the optional rubber crawler your MINI-JETLV can be used like a small HDD drill rig. The rubber crawler has its own petrol engine HONDA GX 390 (10 kW, 13 PS). With the standing plate form for the driver the HDD drill rig is stabilised. With the integrated cylinder the entry angle can easily be adjusted.
