The TERRA MINI-JET MJS 1600 allows to use existing sewer manholes to lay networks for electricity, gas and water without the need to dig up roadways or front gardens of private properties. This innovative pipe laying method was developed over a 2 year period in close co-operation with the French water supplier SADE. TERRA AG has developed such a manhole HDD drill that is able to undertake directional bores from manhole to manhole and from manhole to all near-by homes.
The TERRA MINI-JET MJS 1600 is a manhole HDD drill for directional bores in lengths up to 50 m (165 ft) with a minimum turning radius of 15 m (50 ft).
The directional bore can be reamed in several steps up to 300 mm (12”) even in hard ground. The TERRA MINI-JET MJS 1600 is equipped with a torque of 1600 Nm (1200 ft.lbs) and thrust and pull back forces of 60 kN (6 tons, 13’200 lbs).
Directional bores up to 35 m (115 ft),
Backream diameter up to ø 200 mm (8″).
Mimimum bending radius: 15 m (50 ft).
Manhole-ø 1.0 m (3.3 ft), opening ø 0.62 m (25″)
With drill rod lift. No operator in the manhole. With drill sensor ADBS II.
