A new elevator for use in wellbore operations has been invented which, in certain aspects, has a first body part, a second body part, the body parts together defining a interior opening through the elevator for accommodating a wellbore tubular therein, first hinge apparatus hingedly connecting the two body parts together and permitting the two body parts to be hingedly openable on a first side of the elevator, and second hinge apparatus disposed across from the first hinge apparatus, the second hinge apparatus hingedly connecting the two body parts together and permitting the two body parts to be hingedly openable on a second side of the elevator. In certain aspects such an elevator has at least one roller secured to an interior of at least one of the body parts to facilitate movement of a wellbore tubular with respect to the elevator, and inparticular aspects has a plurality of spaced apart rollers. In one such elevator the plurality of rollers is one or more rollers on each body part. |
