1. A rotary slips lift system for oilfield tubulars, the system comprising:
a movable base adapted to move between a first position and a second position, wherein the first position is closer to a bowl in a drilling rig floor than the second position;
a lifting arm having a first end and a second end, wherein the second end is pivotally coupled to the movable base, and wherein the lifting arm has a first arm position and a second arm position;
a rotary slips, wherein the rotary slips is removably coupled to the first end of the lifting arm, wherein the rotary slips is adapted to be in a first slips position when the lifting arm is in the first arm position and the movable base is in the first position, and the rotary slips is adapted to be in a second slips position when the lifting arm is in the second arm position and the movable base is in the second position, and wherein the first slips position comprises being at least partially located in the bowl and the second slips position comprises being out of the bowl, and wherein the lifting arm is adapted to lift the rotary slips out of the bowl when moving from the first arm position to the second arm position; and
a linkage assembly, wherein the linkage assembly removably couples the first end of the lifting arm to the rotary slips, and wherein the linkage assembly comprises a pinned universal linkage adapter and at least one spring.
