The tube pulling assembly further comprises motive apparatus connected to each of the arm assemblies for moving the arm assemblies to move the tube gripping assemblies into engagement with the tube, and a spring is connected to the arm assemblies for biasing and urging the arm assemblies to move the tube gripping assemblies out of engagement with the tube. A drive assembly is connected to the tube gripping assemblies for rotating the tube gripping assemblies to pull the tube.
