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.
