Energy Equipment Services normally stocks one or two units of HawkJaw Senior and Junior in our premises and also stocks up more than USD 500,000.00 of spares to cater our customers operation within the region. The spares we have stock is very comprehensive and it can meet the needs of our customers.

[0002] A number of apparatuses or machines for making and breaking joints in drill pipe strings are known. A superior and commercially successful machine is the HAWKJAW apparatus available from Hawk Industries, Inc. of Long Beach, Calif.

Versions of it are described in U.S. Pat. Nos. 5,060,542 (Hauk), 5,386,746 (Hauk), and 5,868,045 (Hauk). The HAWKJAW apparatus (or machine or power tong) including both the HAWKJAW JR_ and SR, models, are disclosed in the "HAWKJAW Operation, Maintenance and Service Manual" (Model 100K-ALS-REV 12,99.9200) and "HAWKJAW Operation, Maintenance and Service Manual, Model 65K-ALS, June 2000."

[0006] A chain spinner of the present invention, which can be part of a make/break apparatus (such as the HAWKJAW apparatus) or a separate unit, is an improvement on the "924 patented design. The spinner, for example, can be a free hanging, separate stand alone unit. It can include a unique chain oiler system, which is powered by fluid passing through the spinner motor. When the spray button is pressed the nozzle sprays hydraulic fluid onto the moving chain. The oil can thus only be sprayed when the spinner motor is turning and the chain is moving. Additionally, a chain guide system can be provided for the spinner chain to prevent the chain from bunching up and catching on the sprockets, which is a serious problem in the prior art. This chain guide is another invention disclosed herein. These chain oilers and guides can be adapted to fit on today"s spinners including the SPINMASTER spinner.

[0025] The SPINMASTER spinner can be used on pieces of equipment aside from the HAWKJAW apparatus; alternatively, it can hang on its own. When it is on its own, separate from the HAWKJAW apparatus, the controls and the system can be entirely hydraulic, without any pneumatic component. The spinner has to be running on the pipe and turning the pipe -- that is, the spinner motor 70 pressurized --before the oil will spray on the chain 100 as described above in the "Summary of the Invention."

LosAngeles/132713.1 Patent [0028] The oiler only works when the spinner motor 70 is pressurized, as previously stated. Specifically, the oiler valve will not shift and allow oil to come up into the spray nozzle 80 and spray on the chain unless the motor is pressurized. The fluid flows out of the hydraulic system -- out the spray nozzle 80 onto the chain as the motor is turning. It is powered by fluid going through the spinner motor 70. The nozzle is spraying the hydraulic fluid, which comes from the power unit tank (which has about one hundred gallons capacity). It only sprays for about a second and a half and applies one-twentieth of a gallon for each spray. The user may spray once a day or once a week, for example.

[0031] The chain oiling system can be incorporated on the hydraulic block for the HAWKJAW apparatus. It has a manifold with a triggering valve that takes oil from the spinner valve only when the spinner is running. When the motor is rotating and the spinner chain 100 is thereby moving, the oil is sprayed using spinner motor oil pressure.

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.”

Introduction Hawk"s design philosophy is simple: Design with the end user in mind. Make it tough, dependable and easy to maintain. Hawk has designed the HawkJaw with this same simple formula. FEATURES The HawkJaw 65K-950JR 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 seconds or 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 normal conditions. A patented adjustable wrench system eliminates the need for separate jaws, spinning wrench rollers or gripping dies. The HawkJaw"s modular design enables the unit to be maintained on the rig floor. SAFETY The HawkJaw 65K-950JR provides a fast, safe and efficient method of spinning and make up or break out and spinning. It eliminates costly and dangerous spinning chain and rig tong accidents. TIME AND LABOR SAVINGS The 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 near the 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 HawkJaw 65K-950JR work more efficiently and suffer less fatigue on long round trips. The unit saves

Failure to adhere to these specifications can reduce the efficiency or life of the equipment and/or cause bodily injury.

Warning The 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. Any modification made by any third party without express written consent of Hawk Industries Inc. shall nullify the existing standing warranty.

Hanging Cable Location 1. Anchor the hanging cable to a point as close to the derrick crown as possible. The longer the hanging 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. The cable must hang within 2"-4" ft. of the rotary table center. NOTE The hanging cable must permit the HawkJaw to move from the drill pipe connection to the mouse 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. This allows 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 dual setback 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 the rotary table with the lift cylinder completely stroked out. The lift cylinder is 13" ft. long when completely stroked out.

Hydraulic Requirements 1. Pressure compensated pump set to pressure compensate at 2600 psi. 2. Minimum volume of 20 gpm. 35 gpm for top performance. 3. 1" minimum Pressure line. 1 1/4" Pressure line if the power unit is located more than 100" apart from the HawkJaw. The hose working pressure must be 3000 psi or greater. 4. 1 1/4" minimum Tank line. 500 psi minimum hose working pressure. 5. Hawk approved pressure side non-collapsible on-board 3000 psi filter (HF) (Part # 061H25). Initial filter element supplied with the HawkJaw. 6. Hawk approved quick disconnects (Part # 061-H26). Initial quick disconnects supplied with the HawkJaw. 7. Hydraulic power unit located in a clean, dry, ventilated area. 8. Enough slack in the lines for the HawkJaw to move from its rest position to the drill pipe connection to the mouse hole connection.

The HawkJaw is a closed center system which must have a pressure compensated volume controlled power unit. If the only available hydraulic power unit is constant volume, then the optional hydraulic converter kit (Part # 061-J80) is required. Running the HawkJaw with a constant volume hydraulic power unit may result in bodily injury and will cause damage to the HawkJaw and to the hydraulic power unit.

The HawkJaw must receive clean hydraulic fluid. Running the HawkJaw without a Hawk approved pressure-side filter (Part # 061-H25) voids the warranty and severely shortens component life.

Air Requirements 1. Clean, dry air at 100 psi @ a negligible volume. 2. On board auto-dump air filter (AF) (part# 061-A22), located on board the rear of the Hawkjaw. 3. Enough slack in the line for the HawkJaw to move from its rest position to the drill pipe

WARNING The HawkJaw must receive clean, dry air. Running the HawkJaw without a Hawk approved air filter (AF) voids the warranty and shortens component life.

If this happens, release Torque (T). Immediately release Grip (G). Wait for the Torque cylinder to reset. LOW TORQUE WARNING SYSTEM CHECK Test#1: Hawk strongly recommends testing the Low Torque Warning System on every trip. If this test procedure is not performed, the drill string could be over torqued. Disconnect the Low torque warning test connector (LTC) located as shown. Torque the first connection. Note the torque gage needle position; keep the Hawkjaw positioned on the same connection. Now re-connect the Low Torque Warning Connector. Re-torque the connection. The torque gage should indicate the same reading. If it does not, see Trouble Shooting Test#2:Hawk strongly recommends testing the Low Torque Warning System on every trip. If this test procedure is not performed, the drill string could be under torqued. When breaking the first connection, push in the Grip Hold (GH) button, hold down both Torque (T) and Grip (G) until the Torque Cylinder fully strokes out. When the Torque Cylinder fully strokes out, the Torque Gauge Needle will fall off to approximately an 8000 Ft.- Lb reading. If this does not occur, see Troubleshooting p. 96.

The filter element is clogged. Replace the filter element.  Check the lead-in pressure and tank lines for any obstructions. Also check the quick disconnects to see that they are securely tightened. A bad quick disconnect can cause the Hawkjaw to malfunction. Replace the faulty connector.  The air pressure is low. Increase the air pressure to the HawkJaw.  The hydraulic pressure is low. Increase the hydraulic pressure. Do not increase the pressure over 2600 psi, or the hydraulic fluid will pass over the relief valve and heat up the hydraulic fluid. This will cause damage to the HawkJaw and to the pump, and will severely shorten component life.  Check to make sure the hydraulic power unit is producing 2600 psi at 20-35 gpm.  Check to make sure the hydraulic power unit pressure compensator setting is at 2600 psi.  There ia s leak in the hydraulic system. Check for visual leaks in the hoses, fittings, manifolds, cylinder rod heads, or cylinder rod wipter seals. Replace necessary components.  There ia s leak in the hydraulic system. Operate the Hawkjaw. Feel the outside of all actuators. If a portion of the cylinder surface is too hot to leave your hand on the cylinder, the leak is inside the cylinder. Replace the cylinder seals. If necessary, replace the cylinder. 

The Hawkjaw may have an obstructed tank leadin hose or quick disconnect. Clear the tank line obstruction and or tighten or replace tank line quick disconnect.  Make sure the Low Torque Warning System pressure and tank hoses are properly connected.  Check that the pump pressure compensator setting is at 2600 psi. If the pump pressure compensator setting is above the pressure relief valve setting on the HawkJaw or the pressure relief valve setting on the hydraulic power unit, the hydraulic fluid will heat up rapidly.  There is a leak in the hydraulic system.  Check that the pump pressure compensator setting is at 2600 psi. If the pump pressure compensator setting is above the pressure relief valve setting on the HawkJaw or the pressure relief valve setting on the hydraulic power unit, the hydraulic fluid will heat up rapidly.  There is a leak in the hydraulic system.  If there are no leaks in the hydraulic system, and the pump pressure compensator setting is at 2600 psi on a known, tested hydraulic power unit, and the hydraulic power unit pressure relief valve is set above the pump pressure compensator setting and the hydraulic fluid still heats up, then the pressure relief valve setting on the HawkJaw has been changed. The pressure relief valve adjustment is set at Hawk Industries. Under no circumstances should this pressure relief valve be adjusted. Adjusting the pressure relief valve setting voids the warranty and can cause severe damage to the HawkJaw and the hydraulic power unit and shorten component life. However, if this valve has been adjusted below 2600 psi, and the pressure compensator setting is at 2600 psi, the hydraulic fluid will pass over the pressure relief valve. This will heat up the hydraulic fluid rapidly. Properly set the pressure relief valve adjustment. On a known, tested hydraulic power unit,

set the pump pressure compensator setting at 2650 psi. Use an allen wrench to rotate the pressure relief valve adjustment clockwise until the bypass sound is no longer audible. When the bypass sound ceases, stop rotating the pressure relief valve adjustment. While holding the pressure relief valve adjustment steady with an allen wrench, lock in the adjustment by tightening the pressure relief valve lock nut. Set the pump pressure compensator setting back down to 2600 psi. Adjust the metering valves located on the main manifold.  Check for any visual leaks in the hoses, fittings, cylinder rod head, or cylinder rod wiper seal. Replace if necessary.  There is an inner seal leak in the cylinder. Shut down the hydraulic power unit. Push in and pull out all Grip buttons repeatedly to bleed all hydraulic pressure. Pull out all Grip buttons. Disconnect the air supply hose to the HawkJaw. Disconnect the Raise/Lower cylinder Hanger Eye from the hanging cable. Place the Raise/Lower cylinder Rod side end on the rig floor. Connect the air supply hose to the HawkJaw. Turn on the hydraulic power unit. Push in the Lower button, and hold down the Lower button. While holding down the Lower button, check for Raise/Lower cylinder piston seal integrity. Make sure no bodily parts are in the extension path of the cylinder rod. Slowly loosen the HawkJaw Rod side Leader hose. Check for fluid flow. If there is a piston seal leak, fluid will flow with volume out of the Rod side leader hose. Replace the seals. Replace the cylinder if necessary. Push in the Raise button, and hold down the Raise button. While holding down the Raise button, check for Raise/Lower cylinder piston seals integrity. Make sure no bodily parts are in the extension path of the cylinder rod. 

Remedy Slowly loosen the HawkJaw Cap side Leader hose. Check for fluid flow. If there is a piston seal leak, fluid will flow with volume out of the Cap side leader hose. Replace the seals.
