WRENCH ASSEMBLY WITH ECCENTRICITY SENSING CIRCUIT
First Claim
Patent Images
1. A wrench assembly, comprising;
- a lower clamp assembly;
an upper clamp assembly coupled to the lower clamp assembly that is adapted to move laterally relative to the lower clamp assembly when rotated relative to the lower clamp assembly; and
an eccentricity sensing mechanism coupled between the upper clamp assembly and the lower clamp assembly and configured to stop the lower or upper clamp assembly from applying torque to a tubular connection.

Abstract
A wrench assembly comprising an upper clamp assembly, a lower clamp assembly coupled to the upper clamp assembly, an alignment device disposed between the upper and lower clamp assemblies to allow the upper clamp assembly to move laterally relative to the lower clamp assembly when rotated relative to the lower clamp assembly, and an eccentricity sensing mechanism coupled between the upper clamp assembly and the lower clamp assembly.
