Abstract: An apparatus for lifting a blow-out preventer during oil or gas drilling operations includes a base frame which can be manually positioned atop the rotary table of the drilling platform of the drilling rig used to drill the well. The apparatus further includes a pair of winches which can be lowered to preselected positions on the base frame, after positioning the base frame on the rotary table, and secured to the base frame via pins that extend through clevises that are welded to the base frame and through apertured lugs that are welded to the winches and extend into the clevises. The blow-out preventer is lifted by the winches via cables that are wrapped on reels of the winches and passed through the base frame and rotary table to the blow-out preventer to which the cables are attached.
