1. A break out wrench assembly comprising:
a first subassembly, the first subassembly comprising a first pair of opposing arms linked by a first actuator configured to extend or compress a distance between the first pair of opposing arms; a second subassembly aligned with the first subassembly to receive a longitudinal member therebetween and rotate axially along the longitudinal member in relation to the first subassembly, the second subassembly comprising a second pair of opposing arms linked by a second actuator configured to extend or compress another distance between the second pair of opposing arms; at least one axial actuator coupled to the second subassembly and configured to rotate the second subassembly axially in relation to the first subassembly along the longitudinal member; wherein the first subassembly is mechanically coupled to the second subassembly via an arcuate track defining a platform having a surface extending between opposing edges with the outermost edge horizontally engaging a closed ended recess, the track and closed ended recess confining the vertical relationship of the first and second subassemblies, wherein the platform is coupled to and supported by the first subassembly via a plurality of posts, the posts separating the platform from the first assembly; and a controller coupled to the actuators and mechanically coupled to at least one of the subassemblies. |
