The Ezy-Torque Hydraulic Cathead provides smooth, constantly increasing make-up loads ranging from 40,000 to 150,000 ft-lbs of torque, utilizing either an independent power source or a rig source. This smooth application of line pull force to the rig tongs ensures proper make-up of large, rotary shouldered connections. When the Ezy-Torque Hydraulic Cathead is to be used on connections that require less than 40,000 ft-lbs of torque, the unit should be used in conjunction with a calibrated load cell. The Ezy-Torque Hydraulic Cathead is available in two systems:The Ezy-Torque Model E Type I consists of a cylinder assembly and a self-contained hydraulic power supply that can be temporarily or permanently installed on the drilling rig, preferably on the rig floor.The Ezy-Torque Model D Type II consists of a cylinder assembly, auxiliary hydraulic control unit, remote control module (and hoses) for the control unit and remote control module. The auxiliary control unit plumbs (conversion fittings are not supplied) into an existing rig hydraulic supply such as the accumulator portion of the blow out preventer system.

• Remote control module enables pressure regulation and cylinder operation from a convenient location on the rig
• Hydraulic operation of the remote control module eliminates electrical hazards
• Provides a simple hydraulic circuit for trouble-free performance
• A positive displacement tandem pump provides efficient, steady hydraulic energy
• The cylinder assembly produces the high line pulls necessary to develop make-up torques to 150,000 ft-lbs (203, 400 N•m). It is a key component to both the Model D and Model E Systems. The cylinder assembly includes wireline for connection to the rig tongs.
• Do not exceed the torque rating of the rig tongs.

• Utilizes existing rig hydraulic equipment, minimizing unit space requirements
• Remote control module enables hydraulic pressure regulation from a convenient location
• Hydraulic fluid pressure is regulated through the remote control module
• Air and hydraulic operation of the remote control module eliminates electrical hazards

• Ezy-Torque Model E Type I
• Cycles of power source: 50 Hz or 60 Hz
• Voltage the motor should be wired for. The following are available: 60 Hz – 230V or 460V and 50 Hz – 220V or 380V. Other voltages are available upon special order

• Ezy-Torque Model D Type II
• With or without conversion kit

• The hydraulic auxiliary control unit is designed with a closed center valve for connection to a hydraulic system utilizing accumulators. A conversion kit may be required depending on the rig’s hydraulic power source, such as when powered by a positive displacement pump.
