1. Apparatus for use with a track to move a tubular, comprising:
- a trolley having a shoulder member configured for pushing the tubular in a direction parallel to the track;
a trolley arm moveably coupled to said trolley, said trolley arm configured to be moveable between a released position disengaged from the tubular and a pulling position for moving the tubular in a direction opposite to said trolley pushing direction;
a dog member disposed on said trolley arm and configured for moving said trolley arm when said trolley is at a first predetermined position on the track;
a tubular receiving member; and
a ramp member disposed on said tubular receiving member, wherein when said dog member contacts said ramp member said trolley arm is configured to move to one of said trolley arm positions.

Abstract
A cartridge of tubulars may be removably positioned with a carriage, and the carriage may move the cartridge transversely, vertically, and/or rotationally to roll tubulars on an adjacent tubular receiving member using only gravity from a selected tier of tubulars without human contact. A single trolley disposed with the tubular receiving member both pushes and pulls tubulars toward or away from the drilling deck.
