1. A tubular running tool, comprising:
a mandrel having an elongated body with a longitudinal axis and configured for suspension above a wellbore;
the mandrel having an upper end and a stem portion at an end opposite the upper end;
the mandrel having a plurality of stepped ramps on a surface thereof near a tip of the stem portion;
the mandrel having a plurality of superior ramps on a surface thereof near the upper end;
a plurality of slips disposed on the mandrel;
each slip having an upper end, a lower end, and a stem portion in between the ends;
each slip having a plurality of stepped ramps near the lower end of the slip, configured for complementary engagement with the plurality of stepped ramps near the tip of the mandrel stem portion;
each slip having a stepped ramp near the upper end of the slip, configured for complementary engagement with a superior ramp near the upper end of the mandrel;
each slip configured to receive and retain an insert having a gripping portion on a surface thereof;
wherein the mandrel is configured to engage the stepped ramps and superior ramps thereon with the respective stepped ramps on each slip for actuation of the slips between a neutral position and an extended position;
wherein upon actuation of the slips between the neutral position and the extended position the slips and the inserts disposed on the slips remain parallel to the longitudinal axis of the mandrel; and
wherein the slips are configured for insertion within a tubular such that actuation of the slips to the extended position will urge the inserts to engage the inner surface of the tubular.
