Equipment Specifications at a Glance

The RP6012 is a rugged, self-contained, continuously rotating unit designed to accurately make up or break out threaded connections on tubular components such as oil and gas well drilling tools, casing, tubing, and similar equipment. The manual includes a torque table showing performance at different pressures in both high and low speed, with a maximum rated torque of 50,000 lbs-ft (67,790 Nm) and a maximum system pressure of 3,000 psi (206.1 bar). The unit has a tong and backup gripping capacity of 2-3/8 inches (60.3 mm) to 12-1/4 inches (311.1 mm), a minimum center-to-center die distance of 20 inches (508 mm), and a torque arm length of 24 inches (609.6 mm). Dead weight is approximately 11,300 lbs (5,125 kg) without accessories. The manual also covers recommended hydraulic fluid specifications, grease requirements, and operating temperature ranges.

Installation, Setup & Commissioning

Getting the RP6012 set up correctly is the foundation for safe and reliable operation. This manual walks through receiving and inspecting the equipment, lifting with a forklift using the proper balance procedure, and the optional step of anchoring the unit in place. It covers hydraulic and electronic connections, including a hydraulic schematic and detailed guidance on cleaning and securing hydraulic connections. You will also find instructions for installing jaw and backup dies, placing the unit on a level surface, configuring the load cell, adjusting clamp and torque pressure, and installing a turns encoder on the tong assembly. The manual emphasizes the importance of proper alignment and the use of laser alignment tools before permanently fixing anchor bolts.

Operation & Safety

The operation section begins with operator training recommendations and safety guidelines, then moves into a control panel operation guide that explains each gauge, lever, and switch. Pre-operational checks are listed to help you verify the unit is ready before applying torque. The manual covers initial startup procedures, pipe installation, and the step-by-step process for making and breaking connections. There is also a dedicated section on extreme cold weather operation, which is critical for maintaining performance in low-temperature environments. Throughout the manual, safety warnings and hazard labels are used to highlight areas that require extra caution, including pinch points, rotating components, and hydraulic pressure hazards.

Maintenance & Lubrication

Section 5 is the largest chapter and serves as your maintenance handbook. It opens with general safety practices and cleaning procedures, then covers preventive maintenance and hydraulic system maintenance. The depressurization procedure is spelled out step by step so you can safely work on hydraulic components. Lubrication instructions include detailed grease diagrams for the tong, backup, and skid, with specific lubrication points and recommended amounts. Daily and monthly maintenance checklists are provided to help you build a routine that keeps the unit in top condition. The manual also covers decommissioning, shipping, and recommissioning procedures for long-term storage, including desiccant calculations and corrosion protection guidance.

Troubleshooting & Parts

When something is not working right, the troubleshooting section helps you narrow down the cause. It addresses common issues such as the tong not developing sufficient torque, jaws failing to grip pipe, the tong running too slowly, and the equipment not engaging pipe or providing adequate grip. Each problem is paired with possible solutions. The parts and assemblies section contains exploded-view illustrations and part numbers for the major assemblies, making it easier to identify the exact component you need to replace. From the clamp cylinder to the flow divider, the drive gear assembly to the carriage assembly, the parts breakdowns cover the major components of the RP6012.

Torque Measurement & OEM Documentation

The RP6012 is designed to work with a torque turn management system such as WINCATT, and the manual includes guidance on torque measurement and periodic load cell inspection. Load cells are not user serviceable and must be returned to the factory for repair and recalibration. Section 9 provides links to OEM documentation for components supplied by other manufacturers.
