Rotary drilling rig / horizontal directional / hydraulic / crawler

Swiss manufacturer TERRA AG has unveiled its S-Series Horizontal Directional Drilling (HDD) range, setting new standards in HDD machinery.


Comparing to the it’s big brother TERRA-JET 4015 S, the TERRA-JET 5415 S has a more powerful engine.


The TERRA-JET 5415 S may drill directional bores up to 200 m length and 650 mm (26")diameter (depending on ground conditions). It is driven by a 74 kW (100 HP) powered diesel engine, which is ?clean? and fulfils the required ?green? emission regulations for some years to come. Torque and pullback force are produced by separated hydraulic circuits allowing the maximum torque of 5’400 Nm and the maximum pullback force of 150 kN (15 tons) to be used simultaneously under full load. A rarity nowadays in HDD machines!


The pullback force is produced by a robust hydraulic cylinder. In comparison to hydraulic motors and rack-and-pinion drives of conventional HDD machines, the hydraulic cylinder shows its superiority in hard ground which requires slow backreaming speeds. Here the hydraulic cylinder has its highest efficiency rate whilst hydraulic motors lose up to 25 % of their power at the low rotation speeds required in these hard grounds.
