Geothermal energy with the TERRA-DRILL

    The TERRA-DRILL 150x7 V is a vertical drilling machine for geothermal bores. It can drill (uncased bores) down to 150 m (500 ft) in most ground conditions. It has 15’000 Nm (11’000 ft.lbs) of torque and allows the drilling of 152 mm (6”) casing pipes down to 135 m (450 ft) and their removal without difficulty.

Remote Control

    The TERRA-DRILL is operated via a cable remote control with two joysticks. The operator may stand in a location where he has a view of the entire operation.

Machine Technology

    Two powerful hydraulic motors located in the driving saddle produce a torque of 15’000 Nm (11’000 ft.lbs) and thrust and pulling forces of 70 KN (7 tons, 15’400 lbs); more than most large drills.The TERRA-DRILL is of modular design. It is equipped with an on-board small power pack allowing it to be self propelled. A separate, larger power pack stands can stand independently outside the front garden. Its 97 kW (132 HP) PERKINS Diesel engine drives three independent hydraulic circuits for thrust, rotation and the bentonite pump.


    Its rubber crawlers prevent damage to the garden and pathways and once it has crawled inside the property, through the narrow entranceway, they can be telescopically extended to increase their width from 0.90 m (3 ft) to 1.40 m (4.6 ft). This increases the stability of the rig and prevents it from overturning.


    The four hydraulic outriggers align the drill and transmit the high torque into the ground. The casings and drill rods are 2 m (6.6 ft) long, for fast drilling and removal on completion.

The patented duplex connector
(mud spill preventer)

    The TERRA-DRILL operates with only one driving head. Thus TERRA has designed a new patented duplex connector (mud spill preventer) which allows simultaneous insertion of the casing pipe, the down-the-hole hammer and the drill rods. The duplex connector conducts the drill mud cleanly into the mud containers ensuring that the job site is always clean. As soon as the casings have reached the upper rock edge, the bayonet connection on the duplex connector is released. From that moment on only the drill rods with the down-the-hole hammer proceed to drill further down.


    The duplex connector of the TERRA-DRILL 150x7 V can be aligned longitudinally enabling the drill operator to align the position of the drill bit in relation to the casing pipe bit.
