Abstract
An internal elevator to be received within and internally grip and support a tubular member such as a well platform supporting pile, and including slips preferably mounted within openings in an outer body and actuable radially outwardly into gripping engagement with the tubular member by powered axial movement of an inner camming body. The elevator is desirably suspended in horizontal position by a hanger in a manner enabling the elevator to be stabbed into an end of a horizontal tubular pile or member, with the elevator having additional connector means attachable to a suspending line in a relation then swinging the elevator and pile to vertical positions. In one form of the invention, the elevator may be formed as part of an elongated structure adapted to be lowered through vertically spaced pile guides, with the elongated structure acting to bridge the space between the guides and thereby assure proper alignment of the elevator with the guides and with a pile centered with respect thereto.
