Abstract
Abstract A load carry arrangement with a storage and conveyance of load-carrying roller carts in a loading vehicle in which an endless conveyor is adapted to extend along the longitudinal platform of a cargo carrying vehicle. The arrangement includes a plurality of roller cart-supporting carriers fastened thereto which are adapted to be positioned on a cargo platform in predetermined spaced relationships, and which will facilitate the ready loading and unloading of cargo-carrying roller carts relative to the carriers while assuring the safe storage thereof in the cargo-carrying vehicle. No modification to the carriers or other containers are required, as they are emplaced directly onto the cart-carriers or slave pallets for transit. Space utilization within the truck or other vehicle is maximized with the present design, and the stability of the load emplacement permits ready, rapid cycling of goods within the truck, as in indexing for delivery.
