| Summary: | An apparatus for performing well intervention work on a rig. The apparatus comprises a first spreader that is operatively connected to a derrick, a pair of I-beams that have a distal end and a proximal end, and wherein the distal end of the pair of I-beams are connected to the first spreader. The apparatus further comprises a second spreader, and wherein the proximal end of the I-beams is connected to the second spreader. The apparatus further comprises a first pivot point on the first spreader and a second pivot point on the second spreader. In the most preferred embodiment, the apparatus further comprises a door, operatively attached to the second spreader, for allowing entry of the tubular. Also, the second spreader may include a shoulder for engagement with a tubular so that the tubular is supported by the second spreader so that the weight of the tubular can be transferred to the second spreader. A method of lifting a tubular used in well intervention work on a rig is also disclosed. |
