Abstract

An elevator assembly (100) for moving a tubular member (200), the elevator assembly comprising first and second doors (120a, 120b) each connected to a front side of a body (110) such that the first and second doors rotate between open and closed positions, wherein the body and the doors collectively encircle the tubular member when the doors are in the closed position and wherein a center of mass of the elevator assembly remains substantially unchanged regardless of whether the first and second doors are in the open or closed position.
