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.
