ELEVATOR
An elevator on a drilling rig is a device used to lift pipe or casing. The simplest kind is a hinge clamp or ring with a quick locking device to prevent it from opening when clamped around the pipe. On each side of the clamp or elevator is a lug or eye, which holds the elevator bails or links. The bails are attached to the hoist. The bore of the elevator is slightly larger than the outside diameter of the pipe, permitting it to slip up against the pipe coupling or collar when the pipe is suspended.
