EX60 DEFINING ADVANTAGES

  • SINGLE LAYER, GROOVED KELLY WINCH DRUM

    The Kelly winch is fitted with a large diameter grooved winch drum big enough to keep all of wire rope on one layer and a rear roller. With this combination, speed and consistent linepull are achieved along with excellent rope management and long rope life.

  • PROPRIETARY CONTROLLED FREEFALL KELLY WINCH

    Watson's proprietary controlled freefall winch achieves the performance of prior freefall systems with even greater control over the tool while rapidly decending down the hole. Coupled with a 2-SPEED raise function and the EX series has unbeatable cycle times.

  • TOP APPLIED KELLY CROWD SYSTEM

    Full length top applied crowd drills straighter holes faster and simplifies Kelly locking.

  • INTERCHANGEABLE SQUARE FRICTION OR ROUND LOCKING KELLY BARS

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

  • DUAL DRIVE HYDRAULIC ROTARY SYSTEM

    Dual Drive Rotary enables shiftless operation from 63,000 ft-lbs to 144 rpm spinoff. Without clutches, gear changes or sensors, simplicity, and thus reliability is achieved.

  • FULL EXCAVATOR POWER

    Hydraulics are designed to harness the full horsepower of the excavator and deliver to both the tool and the winch for maximum production.

  • OPTIMIZED AND ISOLATED HYDRAULIC INTERFACE

    Integration to the excavator has been carefully managed to limit the overlap of the systems by providing dedicated valve for the drill. By cleanly separating the two systems, diagnostics, servicing and maintenance of the drill can be distinct from the excavator.

  • BIGGER BARS

    The larger the rotary, the bigger the Kelly bars, the bigger the bearings, the less wear and tear. Larger diameter also means more kelly bars for greater depth without trading off kelly tube thickness and drive lug area.

  • TOOL REACH

    Boom mounted design brings versatility unmatched by mobile mounted rigs. Tool reach of more than 10 ft from the tracks can be achieved on the proper excavator.

  • REDUCED WEIGHT AND SMALLER EXCAVATOR CLASSES

    Unique trunnion & rotary design transfers drilling loads directly from the rotary to the mast thereby reducing weight and stress on the mast. This weight savings allows the machine to be mounted on smaller excavator classes than previous generations of Excadrills.

  • CUSTOMIZATION TO FIT CUSTOMER APPLICATION

    WATSON is a custom manufacturer that welcomes the opportunity to customize rigs. EX rigs can be mounted to numerous makes and models of excavators and further modified to fit specific applications requirements like railcar mount, 10' mast heights, zero turn, etc.


  • Watson has always built the heaviest duty round locking kellys in the business. The latest generation incorporates patented features designed to eliminate the hassle of finding locks while vastly extending 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.
