In some embodiments, the apparatus, or ram block changer, includes a support bracket coupled to a blowout preventer and an articulated arm releasably coupled to the ram block. The ram block changer may further include a pivot coupling assembly having a first axis of rotation. The pivot coupling assembly extends through the support bracket and the articulated arm, wherein the articulated arm is rotatable about the first axis of rotation relative to the support bracket. The articulated aim may include a first member receiving the pivot coupling assembly therethrough, a second member coupled to the ram block, and a second pivot coupling assembly having a second axis of rotation spaced apart from the first axis of rotation and extending through the first and second members. The second member is rotatable about the second axis of rotation relative to the first member.
