T-WREX JR.

IntroductionHawk's design philosophy is simple: Design with the end user in mind. Make it tough, dependable andeasy to maintain.

Hawk has designed the T-Wrex Jr. with this same simple formula.

FEATURES

The T-Wrex Jr. 51200 is a floor mounted unit that will spin, make up and break out drill pipe. It isrevolutionary because the tool spins and makes up drill pipe or breaks out and spins drill pipe in 12seconds or less. A patented self-energized grip system provides consistent torque values to the drillstring. Consistent torque ensures that wash outs and "post tightening" down hole do not occur undernormal conditions.

A patented adjustable wrench system eliminates the need for separate jaws, spinning wrench rollers orgripping dies. The T-Wrex Jr.'s modular design enables the unit to be maintained on the rig floor.

SAFETY

The T-Wrex Jr. 51200 provides a fast, safe and efficient method of spinning and make up or break outand spinning. It eliminates costly and dangerous spinning chain and rig tong accidents.

TIME AND LABOR SAVINGS

The T-Wrex Jr. improves trip time over any comparable torquing and spinning device in the industry. Aremotely located console control unit enables one rig hand to extend and retract the floor mounted uniton and off the pipe.

Control buttons are used to grip, torque and spin drill pipe. Drillers and operators of the T-Wrex Jr.51200 work more efficiently and suffer less fatigue on long round trips. The unit saves trip time becausethe T-Wrex Jr. breaks out and spins in 12 seconds or less, and makes up and spins in 10 seconds orless. Crew fatigue is reduced, pipe is properly torqued and the work is efficient.

Warranty

T-WREX JR. 51200STANDARD WARRANTY AND FIELD SERVICE

Your T-Wrex Jr. 51200 must be free of material and workmanship defects for a period of six months fromthe date of delivery.

Pedestal Mount Location

1. Position the pedestal mount receptacle("female") within the 131" maximumworking radius of the T-WREX pedestalrelative to the rotary table center. Ensurethe position allows for adequate clearanceduring rotation and raise/lower operations.

2. Install the pedestal mount receptacle(12" x 12" x 1/2" wall x 18" longstructural tube) into the decking andsecure by welding per technical draw-ings. The center of the receptacle within131" of the rotary table center .

NOTEThe pedestal mount receptacle location mustpermit the T-WREX to move from the drillpipe connection to the mouse hole connectionto the rest position (3'- 5' ft. away from therotary table center).

1. Place the lower male mount of the T-WREX main post assembly into thefemale receptacle installed into thedecking. The main post must be loweredverticlally into the receptacle to ensure fullengagement.

2. Adjust the shims of the pedestal mountto ensure the main post of the T-WREX isperpendicular to the decking both inall directions.

3. Ensure the T-WREX has adequate clear-ance in all directions to allow for rotationand articulation.

T-WREX Installation

1. Place the T-WREX control console inclose proximity to the rotary table toallow the operator full view of the drillpipe center.

2. Connect the control harness to thecoonector at the back of the controlconsole and secure the lock collar.Theconnectors are keyed for one-wayinstallation only.

3. Connect the other end of th control harnessto the T-WREX ensuring the harness isclear of moving components and pinch-points. Secure the lock collar.

4. Enough harness length is provided toallow the console to be located within safeoperating distance from the rotary tablewith the T-WREX fully extended. Theharness is 10 ft. long. and allows theconsole to be easily moved, as required.

T-WREX Console Installation

1. Pressure compensated pump set topressure compensate at 2500 psi.

2. Minimum volume of 20 gpm. 35 gpm fortop performance.

3. 1" minimum Pressure line. 1 -1/4"Pressure line if the power unit is locatedmore than 100' apart from the T-WREX.The hose working pressure must be 3000psi or greater.

4. 1 1/4" minimum Tank line. 500 psiminimum hose working pressure.

6. Hydraulic power unit located in a clean,dry, ventilated area.

7. Enough slack in the lines for the T-WREXto move from its rest position to the drillpipe connection to the mouseholeconnection.

Hydraulic Requirements

WARNINGThe T-WREX is a closed center system which musthave a pressure compensated volume controlledpower unit. If the only available hydraulic power unitis constant volume, then the optional hydraulicconverter kit (Part # 061-J80) is required.

Running the T-WREX with a constant volume hy-draulic power unit may result in bodily injury andwill cause damage to the T-WREX and to the hy-draulic power unit.

WARNINGThe T-WREX must receive clean hydraulic fluid.Running the T-WREX without a Hawk approved fil-ter (Part # 061-H25) and installed filter element (Part# 061-H25A) voids the warranty and severely short-ens component life.

Air Requirements

1. Clean, dry air at 100 psi @ a negligiblevolume.

2. On-board auto-dump air filter (Part #061-A22). Initial on-board filter (OF)supplied with the T-WREX.

3. Auto-dump air filter (Part # 061-J29)located between the air source and the T-WREX air supply line (A). Initial in-linefilter supplied with the T-WREX.

4. Enough slack in the line for the T-WREXto move from its rest position to the drillpipe connection to the mouse holeconnection.

WARNING

The T-WREX must receive clean, dry air.Running the T-WREX without a Hawk ap-proved air filter (Part # 061-J29) voids thewarranty and shortens component life.

NOTE

Make sure the larger air filter (Part # 061-J29)is mounted vertically with the red and blackarrows on the cannisters pointing up.

NOTE

The smaller air filter (OF) is located on boardthe T-WREX. (Part # 061-A22)
