Abstract
A system that can include slips configured to selectively engage a tubular string that extends into a wellbore, a slips lifter configured to selectively raise or lower the slips, and a link configured to decouple the slips from the slips lifter when the slips are rotated relative to the slips lifter. A method that can include operations of coupling a slips lifter, via a link, to slips on a rig floor, engaging the slips to a tubular, rotating the slips relative to the slips lifter, and decoupling the slips from the slips lifter by decoupling a first element of the link from a second element of the link in response to rotation of the slips.

A system for protecting a slips lifter during a subterranean operation, the system comprising:
- slips configured to selectively engage a tubular string that extends into a wellbore;
- a slips lifter configured to selectively raise or lower the slips;
- and
- a link configured to decouple the slips from the slips lifter when the slips are rotated relative to the slips lifter.

A system for protecting a slips lifter during a subterranean operation, the system comprising:
- slips configured to selectively engage a tubular string that extends into a wellbore;
- a slips lifter configured to selectively raise or lower the slips;
- and
- a link configured to decouple the ships from the ships lifter when the ships lifter attempts to lift the slips with the slips engaged with the tubular string, wherein the slips lifter applies a pre-determined force to the link when the slips lifter attempts to lift the slips with the slips engaged with the tubular string.
