Abstract
Systems, apparatus and methods are usable for automatically engaging and setting slips of an automatic slip setting apparatus about a tubular, when the automatic slip setting apparatus is properly positioned relative to a desired section of the tubular for gripping, lifting and/or holding, and installing and/or removing the tubular, in or out from a wellbore, while preventing slippage and/or dropping of the tubular. The automatic slip setting apparatus is usable with an elevator or spider assembly, each comprising a main body having a central opening extending therethrough, a plurality of slips, and a yoke. An arm assembly, connected to the elevator or spider assembly, moves when contacted by a tubular moving through the central opening, and a latching member, which is connected to the yoke, can be moved by the arm assembly, thereby causing the plurality of slips to move to a closed position for gripping the tubular.
