1 Maximum articulation is defined as the maximum parallel axis offset, and can be varied to suit customer requirements by varying
tool length and articulation angle.
2 Compensated load is the combined weight of all pipe and equipment supported by the tool.
3 Base tool length is representative of a fully collapsed tool. The tool stroke will be added to this length when extended. This does not
include the length of the crossover or saver sub, which is recommended for use with the ACT-3.
4 Tool hoist and torque ratings are based on API Specification 8C, and are valid for any combination of torque and hoist. The rated
capacity does not take into account any limitations that may result from the tool joint connection.

Articulation Compensator Tool (ACT)
Volant’s ACT is designed for casing drilling or running with top drive equipped rigs to eliminate well center
alignment problems. This tool mechanically articulates to align casing or drill pipe with well center.
The ACT is fully compatible with Volant’s Casing Running Tool with internal grip (CRTi
™ ) and external grip (CRTe ™ ).
This patented architecture uses a pneumatic spring and viscous damping system to provide maximum
passive articulation and compensation over the full range of compensated loads.
