Abstract
A slip device includes a housing forming an axial bore, an upper set of slips spaced axially above a lower set of slips, and a rack and pinion actuator radially moving the upper set of slips and the lower set of slips between a retracted position and an extended position to grip a tubular disposed in the bore. The upper set of slips and the lower set of slips can be oriented to resist downward movement of the gripped tubular and to permit upward movement of the gripped tubular. One of the upper set of slips and the lower set of slips can be oriented to resist upward movement of the gripped tubular and the other of the upper set of slips and the lower set of slips can be oriented to resist downward movement of the gripped tubular.
