mjlv_1600In 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.
