cesco power tong dies factory

A two-speed Hydra-Shift® motor coupled with a two-speed gear train provides (4) torque levels and (4) RPM speeds. Easily shift the hydraulic motor in low speed to high speed without stopping the tong or tublar rotation, saving rig time.

Used on corrosion resistant alloys (CRA) and fiberglass tubulars where reduced markings on the tubular is desired. Eckel"s Coated True Grit® Dies utilize Tungsten Carbide grit which provides many more points of contact on the surface of the tubular than our Pyramid Fine Tooth dies.

A patented door locking system (US Patent 6,279,426) for Eckel tongs that allows for latchless locking of the tong door. The tong door swings easily open and closed and locks when torque

is applied to the tong. When safety is important this locking mechanism combined with our safety door interlock provides unparalleled safety while speeding up the turn around time between connections. The Radial Door Lock is patented protected in the following countries: Canada, Germany, Norway, United Kingdom, and the United States.

The WD Tri-Grip® Backup is a high performance no compromise backup that is suitable for make-up and break-out of the most demanding connections. The WD Tri-Grip®Backup features a three head design that encompasses the tubular that applies an evenly distributed gripping force. The WD Tri-Grip®is a high performance backup with no compromises that is available for specific applications that provdies exceptional gripping capabilities with either Eckel True Grit® dies or Pyramid Fine Tooth dies.

The field proven Tri-Grip® Backup features a three head design that encompasses the tubular that applies an evenly distributed gripping force. The Tri-Grip®Backup provides exceptional gripping capabilities with either Eckel True Grit® dies or Pyramid Fine Tooth dies. The hydraulic backup is suspended at an adjustable level below the power tong by means of three hanger legs and allowing the backup to remain stationary while the power tong moves vertically to compensate for thread travel of the connection.

In reference to pipe handling tools used in the drilling industry, there are those generally referred to as "pipe tongs" or "casing tongs". Many of these are fully or semi automated units and are specific to the oil and gas drilling industry, and not within the scope of the present invention. Prior art tools relating to the present invention are more accurately described as "manual tongs", "chain tongs", "Petol tongs", "BV tongs", "Rapspan tong", "pipe wrench", or "stilson", and are identified by having a handle, or lever, which serves to permit load being applied by hand, and, if so designed, also permitting the application of mechanical force to that lever. Prior art tools rely heavily on the casting, forging, machining, and heat treatment processes as necessary to achieve the least practicable weight with the highest possible strength / torque / load capacity, since weight is a critical safety factor when large tools are to be man-handled, such as on waterwell and exploration mobile drillrigs. It has been common for several decades for manufacturers of these drills to fit as standard equipment an adjustable pipe wrench, modified by cutting the handle short, welding a lug to the shortened handle for attatchment to a hydraulic cylinder, for the purpose of applying high torque to the drillpipe and drilling tools. Although relatively lightweight and easy to use, it is an inappropriate modification of a hand tool, and has become the accepted norm within the industry, notwithstanding the well documented injuries resulting from this unsafe practice. These types of breakages are without warning as the component, whether faulty or overloaded, suddenly fails and the tool flies apart, severely injuring any body in its path. United States patent 6119558 seeks to minimise these injuries by the addition of a safety device in the case of such failures.
