Watson Drill Rigs

3110

NOMINAL TORQUE* 154,000 ft-lb (209 kNm)

ACTUAL TORQUE* 128,000 ft-lb (174 kNm)

LINEPULL 32,000 lb (140.8 kN)

DEPTH** 160 ft (48.8 m)

WEIGHT** 90,000 lb (36,320 kg)

The Model 3110 is a strong, powerful drilling machine capable of drilling large diameter drilled shafts. The torque and crowd available with the Model 3110 provide capacity to drill in difficult conditions including hard rock and boulders. The Model 3110 can be mounted on a truck/carrier or on a crawler-type undercarriage with tilt style carbody. A short mast truck mounted or crawler mounted version is available.

* Nominal Torque (aka Rated Torque) is published by all manufacturers but is actually a theoretical calculation that ignores the 15% - 20% efficiency loss present in all rigs.

* Actual Torque is the usable torque at the tool determined through testing of every Watson rig. This value is not typically shared by manufacturers.

**Varies depending on excavator mount and bars

3110 key advantages

CONTROLLED FREEFALL WINCH

Controlled freefall is a critical part of productive drilling. The 3110's controlled freefall rate of speed is adjustable to meet the needs of the operator and demands of the auger and bar arrangement. Combined with 2-speed raise, unparalleled cycle times are achieved.
TOP APPLIED KELLY CROWD SYSTEM

Watson's top crowd system applies the downward force to the top of the kelly rather than through a rotary/bar locking system. The wear and tear on the rotary from crowd forces is eliminated while also allowing the operator to drill straighter holes.
SINGLE LAYER GROOVED WINCH drum

Fitted with grooved winch drum big enough to keep all of wire rope on one layer, speed and consistent pull are achieved along with excellent rope management.
NON-SUPER HEAVY PERMIT LOAD ON 8X4 or 10x6 CRANE CARRIER CHASSIS

The largest truck rig on the market weighs in at less than 90,000 lb. In areas where it is needed, a tri-drive rear or tandem with pusher option can meet strict regulations.
SINGLE LOAD CRAWLER

Set up time is minimal without having to assemble or disassemble to transport, Kelly bars stay installed.
SQUARE friction OR ROUND LOCKING BARS

Heavy duty Kelly bars made from high strength alloy steel are standard on Watson rigs. The 3110 has the option for either square friction or round locking to suit your drilling needs.
MECHANICAL OR HYDRAULIC ROTARY DRIVE SYSTEM

Rotary Drive is available as a mechanical or a hydraulic rotary. Mechanical rotaries, thanks to the torque converter, are known for their speed and responsiveness in many different conditions while hydraulic rotaries are good for hard rock coring and allow the use of more kelly bar elements due to the larger diameter. Both rotaries output 120,000 ft-lbs and the mechanical can reach spinoff speeds of 147 rpm.
made to drill ROCK

Evolved from the 3000 and 3100 drills and all developed for the shallow rock conditions in North America, the entire line has always been designed to take the punishment of drilling rock, and do it for decades not years.
UNRESTRICTED VIEW OF THE HOLE and kelly winch

Helps with precise and safe operation
LATTICE MAST

The ideal geometry for maximizing strength while minimizing weight, 3110 masts are interchangeable and available in short, tall or open back mast versions for air drilling applications.
MAXIMIZED MOBILITY and balance

Rotating frame rotates a full 360 degree, slide frame moves 88" on a truck and 42" on a crawler, boom moves 9 degrees past vertical, there is even 5 degrees of side-tilt in the crawler base. Optimized balance makes it ideal for barge work.
SERVICEABILITY

Open form architecture results in easy access for service and maintenence.
PIlot controls

Pilot controls provide superior control and feel, easier diagnostics and with fewer headaches and obsolescence than electronics.
