TERRA MINI-JET - Pit Launch Machines
TERRA Pit Launch Series MINI-JET
Compact and Powerful
The power and efficiency of TERRA's pit launch machines is extraordinary. With an optimized compact design the Swiss engineers developed a machine with super thrust and pullback force able to work under minimal space conditions
MJ 1400 / MJ 1600
Small Bores with radius of only 15m
You can start the bore directly from a pit of 1.30 x 1.30m in size. The drill rods with the length of only 0.5m allow a minimum radius of 15m. Thrust and pullback force of 60kN (6 tons) is produced by two double cylinders or through a chain drive.
Max. Drilling Length: 50m
Stepwise backreaming up to 300mm Dia
MJS 1600
Drilling from a manhole
The HDD manhole drill MJS 1600 comes with optimized design dimensions. It can drill from manholes with an internal diameter of 1.0m. The operator can sit inside the manhole or control everything from the top via an automatic drill rod lift.
TERRA-JET Pit Launch Machines Series E
Power in the pit - bores up to 420mm Dia
The TERRA-JET Series E has been developed as the most powerful pit launch machine with additional performance increase.
With a thrust force of 80kN (8 tons) and a torque of 3.000Nm you can realise bores witha length of 120m and a backream diameter of 420mm even in hard ground.
TJ 3008 E & TJ 3008 ES
Intelligent break-apart system
The TJ 3008 E is only 2.5m long and 1.0m wide, the TJ 3008 ES is even 0.5m shorter. The minimum turning radius is 35m
The hydraulic break-apart system can be moved to the back in order to pull the new pipe into the starting pit. Two separate hydraulic circuits for 'rotation' and 'thrust' operate without loss of power.
Connectable modules & tools
Power Units, Mixing Stations, Rock Heads
For all pit models the pit drill is connected to a power pack and an external mixing and pumping station which produces the Bentonite drilling fluid. Rock heads allow rock drilling.
