Watson's top crowd system applies the downward force to the top of the kelly rather than through a rotary to outer bar locking system. The controllable outer bar eliminates the locks from the outer bar for crowding.  The wear and tear on the rotary from crowd forces is eliminated while also allowing the operator to drill straighter holes.  

Clearance for a 14 (14.3) foot tool around the track corners at full reach and up to 6 ft (1.8m) diameter up the mast.  An 8 ft (2.4m) tool is shown easily clearing the tracks in the raised up drilling position.

Hydraulic system separation between CAT excavator and the drill allow for better isolation and diagnosis of issues.  Open architecture hydraulic box results in easy access for service and repair.

Heavy duty Kelly bars made from high strength alloy steel are standard on Watson rigs. The 7300 has interchangeable inserts to allow for either square friction or round locking to suit your drilling needs.  

Watson's proprietary controlled freefall winch achieves the performance of other freefall systems with even greater control over the tool.  Paired with a large diameter grooved drum and a rear roller, wire rope management is best in class.

Watson has always built the heaviest duty round locking kellys in the business. The latest generation incorporates patent pending features designed to eliminate the hassle of finding locks while vastly extend the time between servicing. With 4x the torque surface and 12x the crowd surface, customers are able to go years between refurbishing bars. Additionally, open bottom design allows easy drainage for slurry drilling. Call for details.

The triple drill motor design achieves max torque and max spinoff without clutches or gear shifting.  The spindle passage for a 22" bar is the largest in the industry allowing for more kellys with larger drive lugs.

Time tested pilot controlled primary valve married to the Next generation CAT control system provide superior control/feel and easier diagnostics.  Manual levels on all section allow for even easier diagnostics or override.

Triple grouser expandable undercarriage with a square foot print for 360 deg stability at full parallelogram reach (for short mast). 9'4" retracted to 13'7" expanded. Clearance around tracks for a14 foot tool.

New evolution of short mast design, uses a top drive rotary which allows for the additional kelly elements under the rotary that allow for unmatched drill depths.
