Eckel offers a broad range of accessories to compliment our power tongs. From torque control systems and gauges to case handles and tong straps, Eckel has the right accessory option for your specific application.

Eckel offers torque control systems to monitor the torque turn values when making up tubular connections with the system automatically stopping tong operation once reaching a specific torque. Any flaws in the make-up process will be readily shown in a graph.

The Door Interlock is offered as an optional safety feature for use with the power tong to prevent accidental operation of the power tong when the door is open. The door interlock prevents tong operation whenever the tong door is open by impeding hydraulic fluid to the tong motor.

A hydraulic Tri-Grip® or Cam Backup tool is optionally supplied with Eckel tongs. In operation this tool provides a backup when in break-out or make-up situations. This hydraulically operated backup tool, uses hydraulic cylinders and a head arrangement to insure slip-free operation.

A standard feature on many of our tongs. Dies have evolved since tongs became commonplace in the oilfields. Eckel has been at the forefront of this developing technology with the development of larger wrap-around type dies for many of its tong models. We offer coarse tooth design for normal carbon steel pipe and collars and fine tooth for special alloys such as 9, 13, 23, 25 chrome and fiberglass to greatly minimize markings on the tubulars.

Designed for improved safety when handling the tong. Up to four Case Handles can be optionally mounted on most tong models. Large top and bottom caps help protect the operator when maneuvering the tong on and off the tubulars.

Eckel continues to set industry safety standards with the optional Finger Guard Option. This shield covers the gap between the tong door and tong body, without limiting door operation. Door will open and close freely.

Industrial strength straps feature a rubber gripping surface to allow for easily pulling the tong on and off the tubular. These optional straps are mounted on the tong door and on both sides of the solid hanger area of the tong using a Lark"s Head Knot.

The adjustable motor port relief valve is used to control or limit the hydraulic pressure to the tong motor thus controlling the maximum torque output of the power tong. The valve controls only the hydraulic pressure to the tong motor leaving full system pressure available for other functions such as lift cylinder and hydraulic backup.

RPM Control: The RPM Control is a flow divider that decreases the amount of hydraulic fluid that reaches the tong, the remaining fluid is returned to the reservoir. By decreasing the amount of fluid reaching the tong the operator is able to control the maximum RPM"s the tong will deliver.

Tongs equipped with the optional Swivel Joints have improved hose life by absorbing system shock when pressured up and preventing twisting, kinking of the hydraulic hoses. In addition tongs are maneuvered more freely on the rig floor on and off the tubular.

The optional torque gauge assembly is used to measure the torque exerted in make-up or break-out operations. Consisting of a hydraulic cylinder and torque gauge connected together by a pressure hose, the torque gauge assembly senses and indicates the torque developed during an operation. For operation, the hydraulic cylinder is connected by a shackle to the rear of the tong; and a snub line is connected to the cylinder. The snub line is tied off to a solid part of the rig structure to form an angle of 90� in order for the gauge to indicate accurate torque readings.

This cylinder provides a means for raising and lowering the tong during operations and is recommended with tongs that have a hydraulic backup due to the extra weight of the tong. The lift cylinder maximum of travel varies depending on tong size.

The optional spring hanger is designed to permit the tong to move up or down to allow for thread length in make-up and break-out operations. When used, the spring hanger should be attached directly to the tong bridle ring and used as a hanger for the tong.

The tong should be secured for both make-up or break-out operation, by utilizing the snub line. If this is not done, the tong may be thrown against operator causing physical harm.

When using the mechanical shift lever to change speeds, the power tong must first come to a complete stop before shifting. When using tongs hydraulic shift two-speed motor to change speeds, the tong may be shifted "On the Run."

Eckel tongs have proven to basically to last forever with minimal maintenance as all they are manufactured with the highest quality of steel. Using Eckel equipment tells your customer that you have the highest quality equipment on the market.

Tong size is determined by range of tubulars you will run. For example a 5-1/2 Hydra-Shift® is capable of running tubulars 5-1/2-inches and smaller while the 14 UHT is capable of running tubulars 14-inches and smaller. It is important not to use a large range of sizes with just one tong. If you have a 10-3/4 Standard and you regularly run 4-1/2-inch tubing with this tong, you might consider using a smaller tong.

PSI pressure determines the maximum torque the tong will safely be able to reach. Eckel rates all their tongs at the industry standard 2500 PSI. A competitor with a similar size tong may show more or the same torque as an Eckel tong due to a higher PSI from the power unit (which is in fine print) in an effort to fool you, thinking there tong is equal to the industry standard (Eckel tong.)

Gallons Per Minute determines the rotational speed of the tong. A low GPM will cause the tong to operate at a lower speed while a high GPM will result in the tong to rotate at a higher speed. Eckel offers an RPM (Revolutions per minute) Control which is a flow divider to decrease the amount of hydraulic fluid that reaches the tong if needed, the remaining fluid is returned to the power unit reservoir. By decreasing the amount of fluid reaching the tong the operator is able to control the maximum RPM of the tong.

Field tests have shown depending on several factors most power units used in above 32 degrees Fahrenheit conditions no matter if your hydraulic oil tank holds 200 gallons of oil, will exceed 150 degrees during a short 8 hour job. Most power units without hydraulic oil coolers exceed 170 degrees which is way past the recommended guide lines.

The keeper screws may be located inthe centre of the jaw assembly (see Illustration 2.E.2), or on one end of the dies. The dies may need to be lightly tapped with ahammer to break them free from the jaw. Similarly a new die may need to be lightly tapped to completely seat it into the dovetailgrooves in the jaw. Ensure the keeper screw are reinstalled following jaw die installation.Illustration 2.E.2: Jaw Die Removal3. Backup JawsThe jaw die kits used in the Farr backup are identical to those used in the lightweight tong (see Pp. 212). Follow the sameremoval and installation instructions as for the tong jaw die kits.F. TONG RIG-UP & LEVELING1. Suspension & RestraintSuspend the tong and backup from a location as near to the centre of the drill rotary as possible, and from a location high enoughon the mast to ensure easy handlng. The lower the point from which the tong is suspended, the more effort will be required tomove the tong to and from the connection point.The suspension line may be extended over a pulley and balanced by a counterweight equal to the weight of the tong and backup,or simply tied off in the derrick to form a dead line. When using a dead line arrangement it is necessary to use a FARR springhanger assembly (see specification page for recommended spring hanger). This spring hanger compensates for the downwardmovement of the casing as the thread is made-up, and imparts additional force to the suspension cable:●●a “single spring” hanger typically applies 420 lbs. (191 kg.) to the suspension line for every inch of thread made up●●a “double spring” hanger typically applies 840 lbs. (382 kg.) to the suspension line for every inch of thread made upIf you do not know which specific spring hanger is in use, check the specification page in this manual for information on therecommended spring hanger for this application. McCoy Drilling & Completions will not guarantee or specify spring hangersother than what has been supplied by McCoy.Many applications use a lift cylinder for adjusting the height of the tong. Ensure the weight of the lift cylinder is known if it hasnot been included in the total weight of the tong.All forces upon the suspension line must be considered when calculating necessary strength of the suspension line. The weightof the tong, the weight of the lift cylinder, the weight of the spring hanger, and the force imparted on the suspension line by thespring hanger must all be added together in order to arrive at the total force supported by the suspension line.Technical ManualSection Contents 2.13

LW9625 9- 5 / 8” Tong & FARR® BackupSetup & OperationSuspension & Restraint Continued:Select your suspension line based upon the total force and the margins of safety dictated by the policies of your company andby established engineering practices. Ultimately, calculating the force on the suspension line and selection of the suspensionline is the complete responsibility of the customer.McCoy Drilling & Completions recommends using dual backup (snub) lines of sufficient strength to withstand the force impartedby the maximum rated torque of the tong and backup assembly in use. The snub lines will arrest uncontrolled movement of thetong and backup in the event slipping of the backup jaws. Calculate the force on the snub lines by dividing the maximum torqueof the tong by the tong’s torque arm (expressed in feet). For example, an 12,000 lbs.-ft. tong with a 31 inch (2.583 ft.) torquearm will generate 4645.2 lbs. of force against the snub line. Select your snub lines based upon the total force and the marginsof safety dictated by the policies of your company and by established engineering practices. Ultimately, calculating the force onthe snub line and selection of the snub line is the complete responsibility of the customer.Snub lines must be securely connected to the rear of the tong and backup assembly, and tied off to a suitable anchor.farr canada corp. ACCEPTS NO RESPONSIBILITY FOR DESIGNING AND SELECTINGAN ADEQUATE SUSPENSION and restraint SYSTEM FOR YOUR DRILLING EQUIPMENTall selected fasteners, shackles, clamps, etc. used for constructing thesuspension and snub lines must be rated for the calculated forces.2. Tong LevelingThe tong must be leveled side-to-side and front-to-rear before placing into service. The following guidelines wil assist you whenleveling your tong.i. Place a level axially (side to side) across the tong, ensuring that it is parallel with the surface of the tong.Use a thin wrenchon the flat of the adjusting helix to rotate the helix, forcing the lift link to move towards the outer supports of the sling.The 3/4” nylock nut on the pin may have to be slightly loosened to allow the helix to rotate. Adjust the helix until the levelshows that the tong is level side-to-side.Rotate helixusing flat3/4” Nylock nut mayhave to be loosenedIllustration 2.F.1: Tong Leveling (Side-To-Side)2.14 Section Contents Technical Manual
