Abstract

A pipe retrieval machine includes a frame defining a decoupling region and a travel axis and a transporting mechanism supported on the frame. The transporting mechanism has a first gripping structure adjacent an infeed end of the machine and a second gripping structure adjacent an outfeed end of the machine. The decoupling region is between the first and second gripping structures. The machine has a drive system to move the first and second gripping structures at a steady state speed to direct a pipe along the travel axis. The pipe retrieval machine includes one or more safety features to stop the drive system either automatically or through manual action, one or more safety features to inhibit or prevent damage to components of the decoupling region in the event of a malfunction, or both. Methods of operating a pipe retrieval machine include any of the operation procedures, method steps, safety features, and/or functions as described and in any combination.
