Abstract
A wrench assembly comprises upper and lower clamp assemblies each having a plurality of grip assemblies, a plurality of torqueing cylinders, and a hydraulic circuit. The hydraulic circuit is in fluid communication with the grip assemblies and the torqueing cylinders and is configured to control a gripping force applied by the grip assemblies relative to a torqueing force applied by the torqueing cylinders. The hydraulic circuit is configured to maintain the gripping force in a proportional relationship with the torqueing force.
