A portable crane for removable attachment to a safety rail system. The portable crane attaches to one or more guide rails on the safety rail system and is configured to raise and lower payloads without obstructing the roof hatch. The portable crane includes a planar ballast platform that lays flat on a roof, a winching mechanism affixed to a vertical post, and a boom extending at an angle from the vertical post. A pulley at an end of the boom permits the raising and lowering of a payload through the roof hatch. The ballast platform and vertical post may be removably attached to the guide rails with one or more U-bolts.
