ABSTRACT:
A portable power operated apparatus that may be positioned adjacent a first stack of lengths of oil well tubing having collars screwed on first ends thereof. The lengths of tubing are subsequently removed from the first stack onto the apparatus. Each length of tubing after being disposed on the apparatus is power rotated with the collar being removably held stationary relative to the tubing to separate the collar therefrom. The collar after removal is inspected, and if found satisfactory for further use is directed to the rearward end of the apparatus. The collar at the rearward end of the apparatus is removably gripped in a reverse position and screwed onto the second end of the tubing by rotating the latter. The length of tubing with collar attached is then lifted by the apparatus and moved to a second stack of tubing where it remains until again needed.
