The company’s focus on vertical drilling equipment has paid off. It was awarded Manufacturer of the Year at the 2014 Oil & Gas Awards and it holds several patents for its innovative products. The company produces four main lines, the T-WREX, T-WREX Junior, HAWKJAW and SPINMASTER, and among these products Hawk Industries is able to cover a gamut of needs.

The HAWKJAW is Hawk Industries’ flagship product and has been continuously improved after years of design and testing. The make-up/break-out tool combines spinning and torque wrenches in a modular design for easy maintenance and servicing. It has a self-energized grip system and optimizes drill crew size by combining tongs, spinner and spin chains into a single unit. The HAWKJAW also improves safety with fewer cables, snub lines and pull chains required on the rig floor.

The T-WREX and T-WREX Junior feature the HAWKJAW on a pedestal-mounted configuration for remote operations. It’s ideally suited to the harsh environments of offshore drilling or large-scale land-based operations. The SPINMASTER, which the company says is one of the fastest, safest and most efficient drill pipe spinners on the market today, is available in pneumatic or hydraulic models and in two sizes. It has a high torque output of 2,272 feet per pound while its compact design makes it lighter than comparable tools. Allshouse says that all of its tools are designed for maximum flexibility.

“We try to design products that you can use on any vertical rig,” Allshouse says. “Like the HAWKJAW, it was designed to move from rig to rig, so it’s easy to take down and easy to put away. All the product lines use the same spare parts, so if you have a HAWKJAW and a T-WREX, you can interchange spare parts. We really focus on availability of parts to get the customers what they need for after-sales service and on designing flexibility into our equipment.”

IntroductionHawk"s design philosophy is simple: Design with the end user in mind. Make it tough, dependable andeasy to maintain.Hawk has designed the HawkJaw with this same simple formula.FEATURESThe HawkJaw 65K-ALS is a hanging unit that will spin, make up and break out drill pipe. It is revolutionary because the tool spins and makes up drill pipe or breaks out and spins drill pipe in 12 secondsor less. A patented self-energized grip system provides consistent torque values to the drill string.Consistent torque ensures that wash outs and "post tightening" down hole do not occur under normalconditions.A patented adjustable wrench system eliminates the need for separate jaws, spinning wrench rollers orgripping dies. The HawkJaw"s modular design enables the unit to be maintained on the rig floor.SAFETYThe HawkJaw 65K-ALS provides a fast, safe and efficient method of spinning and make up or breakout and spinning. It eliminates costly and dangerous spinning chain and rig tong accidents.TIME AND LABOR SAVINGSThe HawkJaw improves trip time over any comparable torquing and spinning device in the industry.The unit easily adapts to any land or offshore rig because it hangs in the derrick. Handles mounted nearthe control buttons enable one rig hand to move the hanging unit on and off the pipe.Control buttons are used to grip, torque and spin drill pipe. Drillers and operators of the HawkJaw65K-ALS work more efficiently and suffer less fatigue on long round trips. The unit saves trip timebecause the HawkJaw breaks out and spins in 12 seconds or less, and makes up and spins in 10seconds or less. Crew fatigue is reduced, pipe is properly torqued and the work is efficient.

CAUTIONFactory specifications for hydraulics, pneumatics, lubricants, adjustments and safety precautions as setforth in the operation and maintenance manual are for the mutual protection of the owner of the HawkJaw65K-ALS or 100K-ALS and the company. Failure to adhere to these specifications can reduce theefficiency or life of the equipment and/or cause bodily injury.

WarningThe Hawkjaw includes specially modified valves, fasteners and other components for extreme environments and service. Any attempt to substitute standard components could reduce reliability and performance, void the warranty and/or cause bodily injury.

NOTEIf the only available hydraulic power unit is open center, then a Hawk supplied hydraulicconverter (Part # J-80) is required. Running the HawkJaw with a constant volume hydraulicpower unit may result in bodily injury and will cause damage to the HawkJaw and to thehydraulic power unit.

Hanging Cable Location1. Anchor the hanging cable to a point as close to the derrick crown as possible. The longer thehanging cable, the easier the HawkJaw is to move on and off the drill pipe.2. Locate the cable hang point as high above the center of the rotary table as possible. Thecable must hang within 2"-4" ft. of the rotary table center.NOTEThe hanging cable must permit the HawkJaw to move from the drill pipe connection to themouse hole connection to the HawkJaw rest position (3"- 5" away from the rotary table).

1. Place the HawkJaw on the side of the rotary table away from the setback zone. Thisallows the drill pipe stands to swing straight from pick-up to stabbing.2. If possible, place the HawkJaw on the opposite side of the setback zone. If the rig has dualsetback zones, Step 1 applies.3. The HawkJaw may rest on the rig floor 3" -5" ft. away from the rotary table.

5/8" diameter steel cable.Appropriate hanging cable hardware for 5/8" diameter steel cable.Enough cable length to suspend the Hanger Eye (HE) 20" ft. above the rig floor.Enough cable length to allow the HawkJaw to rest on the rig floor 3"- 5" ft. away from therotary table with the lift cylinder completely stroked out. The lift cylinder is 13" ft. longwhen completely stroked out.

SymptomRemedyHydraulic fluid heats up.(cont.) l If there are no leaks in the hydraulic system, and thepump pressure compensator setting is at 2600psi on a known, tested hydraulic power unit, and thehydraulic power unit pressure relief valve is setabove the pump pressure compensator settingand the hydraulic fluid still heats up, then thepressure relief valve setting on the HawkJaw hasbeen changed. The pressure relief valve adjustmentis set at Hawk Industries. Under no circumstancesshould this pressure relief valve be adjusted. Adjusting the pressure relief valve setting voids thewarranty and can cause severe damage to theHawkJaw and the hydraulic power unit andshorten component life. However, if this valve hasbeen adjusted below 2600 psi, and the pressurecompensator setting is at 2600 psi, the hydraulicfluid will pass over the pressure relief valve. Thiswill heat up the hydraulic fluid rapidly. Properly setthe pressure relief valve adjustment. On aknown, tested hydraulic power unit, set the pumppressure compensator setting at 2650 psi. Usean allen wrench to rotate the pressure relief valveadjustment clockwise until the bypass sound is nolonger audible. When the bypass sound ceases, stoprotating the pressure relief valve adjustment.While holding the pressure relief valve adjustmentsteady with an allen wrench, lock in the adjustmentby tightening the pressure relief valve lock nut. Setthe pump pressure compensator setting backdown to 2600 psi. See Drawings, p. 102.

There is an inner seal leak in the cylinder. Shutdown the hydraulic power unit. Push in and pullout all Grip buttons repeatedly to bleed allhydraulic pressure.Pull out all Grip buttons. Disconnect the airsupply hose to the HawkJaw. Disconnect theRaise/Lower cylinder Hanger Eye from thehanging cable. See Installation, p. 10, Drawings, p.130. Place the Raise/Lower cylinder Rod side endon the rig floor. Connect the air supply hose tothe HawkJaw. Turn on the hydraulic powerunit. Push in the Lower button, and hold down theLower button. While holding down the Lowerbutton, check for Raise/Lower cylinder piston sealintegrity. Make sure no bodily parts are in theextension path of the cylinder rod. Slowly loosenthe HawkJaw Rod side Leader hose. Check forfluid flow. If there is a piston seal leak, fluid willflow with volume out of the Rod side leader hose.Replace the seals. See Drawings, p.100. Replacethe cylinder if necessary. See Drawings, p. 130.Push in the Raise button, and hold down the Raisebutton. While holding down the Raise button, checkfor Raise/Lower cylinder piston sealintegrity. Make sure no bodily parts are in theextension path of the cylinder rod. Slowly loosenthe HawkJaw Cap side Leader hose. Check forfluid flow. If there is a piston seal leak, fluid willflow with volume out of the Cap side leader hose.Replace the seals. See Drawings, p. 100.
