POWER
These drilling rigs have large engine and hydraulic capacities. This translates into the rigs being able to use far more powerful winches for the Kelly bar, crowd, and pullback, as well as faster rpm at higher torque when drilling with casing in overburden. The beefed up structure can also support the additional stresses put on the rig with stronger winches.
DESIGN
Numerous design features result in less downtime and longer equipment life.
The rigs are based on reinforced CAT carriers so spare parts are easy to obtain.
