In its long version the MINI-JET MJLV is one meter loger than the normal MINI-JET. With 1.5m long drill rods you can drill up to 120m and backream up to 300 mm, also in hard ground condition. The MINI-JET is driven by a Kubota 24kW engine and offers 1’600Nm of torque and 60kN(6 tons) of thrust and pullback force.
The MINI-JET LV can be adapted with rock drilling tools for hard ground conditions.

[restab title=”Rubber crawler(Optional)”]
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.
