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

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

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.

Quad-Drive Rotary enables shiftless operation from 180,000 ft-lbs to 90 rpm spinoff. Without clutches, gear changes or sensors, simplicity, and thus reliability is achieved.

Watson's larger rotary designs allow for bigger the Kelly bars and rotary bearings, which lower the wear and tear on the business end of a drill rig. Larger diameter also means more kelly bars for greater depth without sacrificing kelly tube thickness and drive lug area.

Heavy duty Kelly bars made from high strength alloy steel are standard on Watson rigs. The EDT18 has interchangeable inserts to allow swap out for either square friction or round locking to suit your drilling needs for any given job. Up to 5 elements available.

Boom mounted design brings versatility unmatched by mobile mounted rigs.

Unique trunnion design simplifies the process of removing the drill for transport.  No crane is required as the excavator can load the drill unit.

From Custom paint schemes to Kelly bar stubs, Mast heights and Kelly bar lengths to meet your drill depth demands. Further more these can be mounted to any make excavator from 35-50 metric ton.

Keeps the cables tight and takes up any slack as the cables stretch. Makes changing or adjusting the cables easier.

With the press of a button, full torque can be applied without adjusting the torque/speed settings. The benefit is the ability to quickly power through tough conditions.
