US Patent 11905768 Compensating rig elevator

A compensating rig elevator is provided to eliminate set-down weight from threaded connectors during make-up of a pipe stand and thereby provide an ability to reduce the risk of thread galling and cross-threading. The elevator may comprise one or more hoist assemblies with bail arms that deflect as the compensating rig elevator is suspended by the bail arms and a tubular is placed in the compensating rig elevator. The bail arms actuate a locking mechanism to secure the compensating rig elevator in a closed position around the tubular. The compensating rig elevator can also have compensating rams and a slip system to positively engage the tubular and bear the weight of multiple tubulars.
