Case Histories

Forum Energy Technologies’ AMC high-torque (HT) stroking machine is designed for fast and accurate makeup and breakout of threaded connections on drilling tools, well completion assemblies and other oilfield related equipment, up to a maximum torque of 250,000 ft-lb.

Optimized for efficiency and safety

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

Both heads feature hydraulically controlled clamp cylinders that can go from 3 to 28 in. OD, or up to the machine’s maximum diameter, without the need to change jaws between sizes. 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.
