ABSTRACT:
A storage track section for a power and free conveyor system having carriers each comprising a leading driving trolley, a first load carrying trolley connected to the driving trolley by a tow bar, and a second load carrying trolley connected to the first load carrying trolley by load carrying structure. The storage track section includes parallel first and second load tracks which respectively support the first and second load carrying trolleys and are transversely spaced apart a distance less than the length of the load carrying structure; and, includes a driving trolley track located intermediate and parallel to the load tracks and transversely spaced from the first load track a distance less than the length of the tow bar. An entrance section to the storage track section is so arranged that the three trolleys of each carrier are diverted to their respective storage section tracks in a sequence which places the tow bar and the load carrying structure in a jackknifed relation, thereby enabling a given number of carriers to be stored in a minimum area.
