A well lift frame, clamp assembly therefor, and method for handling well equipment is disclosed. In an embodiment, the lift frame includes a frame, a vertical slot forming an opening in a side of the frame, and a clamping assembly mounted to the side of the frame near the opening. The clamping assembly may include a linkage assembly arranged so as to travel along an arcuate path between a disengaged position, in which the clamping assembly is substantially clear of the opening, and an engaged position in which the clamping assembly at least substantially covers a horizontal extent of the opening. The linkage assembly may define a four-bar linkage mechanism. The clamping assembly may also include an actuator coupled to the linkage assembly so as to selectively position the linkage assembly, and a shoe carried by the linkage assembly for contacting and clamping equipment within the vertical slot.
