A mobile lift crane includes a carbody having movable ground engaging members; a rotating bed rotatably connected to the carbody; a boom pivotally mounted on the rotating bed; a first hoist drum mounted in a first frame connected to the rotating bed; a second hoist drum mounted in a second frame connected to the rotating bed. Connectors used to connect the load hoist drum frames to the rotating bed include engagement members and alignment surfaces such that as the two crane components are brought close to their operational position during an assembly operation, the engagement member and the alignment surface of the connectors come into contact with one another to guide the crane components into their operational orientation so that a main pin can be placed through the through-holes of the extensions of the connectors.
