An improved trolley structure for a freight bracing bulkhead assembly. The sprocket wheels of the trolley structure are designed to cooperate with the same apertures in supporting tracks located in a cargo area as cooperate with the locking pins of the bulkhead assembly. The sprocket wheels are mounted on the trolley shaft by means which permit the axis of each sprocket wheel to shift relative to the axis of the trolley shaft. A safety member is provided to prevent vertical disengagement of the sprocket wheels from the tracks.
