Case Histories

Forum Energy Technologies’ AMC fully rotational torque (RT) bucking machine is designed for fast and accurate makeup and breakout of premium and non-premium threaded tubular equipment. The machine can handle up to a maximum torque of 200,000 ft-lb tracking thread, and run in from as low as 200 ft-lb.

The RT bucking machine is powered and controlled by an AMC hydraulic power unit (HPU). Over the years, Forum has redesigned the HPU to incorporate customer feedback and industry requirements to improve user ergonomics, makeup accuracy and process cycle times. 

Optimized for efficiency and safety

The self-contained, free-standing, hydraulically powered torque machine consists of a fixed headstock and a traversing tailstock, which are available with a hinged top-opening feature to help ensure tools are loaded safely and efficiently.

The stocks feature hydraulically controlled clamp cylinders that can go from 2 3/8 to 48 in. OD, or up to the machine’s maximum diameter size, without the need to change jaws between sizes. This has proved to be beneficial since it can reduce downtime, while decreasing safety hazards associated with changing jaws manually.

The hydraulic system works at low working pressures, eliminating the need for high-pressure hoses and fittings, lowering component costs and improving safety to the customer.

All machines are delivered with a one-year OEM warranty for peace-of-mind operation. The system is robust enough to withstand virtually every environment, including extreme heat and cold temperatures for extended and prolonged workshop use.
