KBK system is used for the transportation and storage of aircraft wings. In this KBK system, the characteristic design lies in the design of turning. Because the length of the wing or fuselage shell is too long and the curved rail is too close to the wall, the inner and outer curved rails are adopted, which can avoid the fuselage hitting the wall. In addition, because the wing and fuselage shell can't land on the ground, the locking device (over-span mechanism) of monorail and single beam can transport the parts on monorail crane to single beam and directly hang them for storage.
It is a kind of transportation and storage mode for such components. In addition, a single beam can be used as a transportation device, while a monorail can be used as a storage mechanism.
