The invention relates to the technical field of aircraft structural design, and specifically provides an aircraft cargo compartment crane beam. A plurality of hook joints and at least one stop hook joint are fixed on a crane beam, and a base structure is arranged on a frame of an aircraft cargo compartment. Hooks of the hook joint and the stop hook joint are hung in hook holes of the base structure, and the hook head of the hook joint has a pointed shape. The hook head of the stop hook joint has a square shape, and the top surface thereof is provided with a groove. Two sides of the hook hole of the base structure are symmetrically provided with through holes. A quick release pin penetrates the through hole and the groove to fix the stop hook joint and the base structure. The crane beam isfixed to the aircraft base structure through a method that the quick release pin is cooperated with the hook. The crane beam has low weight cost and is easy to handle.
