Tailing and Stabbing Arm (TSA)
The McCoy TSA is a hydraulically activated pipe-handling system that delivers precise, hands-free control of casing and drill pipe from 4½" to 13⅜" — from catwalk to stabbing position.
Engineered for accuracy, the TSA uses sensory feedback at three articulation points to ensure perfect tubular alignment every time. Its extended reach keeps equipment clear of well center when idle, while built-in valve protection eliminates uncontrolled movement.
Hands-Free Operation. Zero Red Zone Exposure. The TSA is purpose-built to take personnel out of harm's way. By fully automating tubular handling and alignment, it eliminates the need for manual tailing and stabbing — keeping your crew clear of the Red Zone and away from pinch-point hazards throughout every connection. The result is a cleaner, safer rig floor where people and equipment never compete for the same space.
Less risk. More precision. Built for the way you work.
