ABSTRACT:
This invention is an oblique fork or channel parallel moving transfer system especially for lift or stacker vehicles for storage and retrieval of containers such as automobile parking pallets, racks, parts boxes, etc. on storage shelves, platforms or racks including those having a plurality of tiers for storing the containers. It can serve as a parking garage, warehouse or other storage-retrieval system. The lift vehicle has a lift or fork bed with one or more oblique channels or forks extended to engage a line of rollers or cooperating slide member on the container to move the container out from the tier and support it when the vehicle is engaged and moved parallel to the facing side of the tier. The vehicle lifts and lowers and rolls along an aisle for transfer to and from racks on either or both sides. Two cooperating lifts columns are at opposite corners farthest from the channel for transfer clearance to and from either side. End loading ramps extend over the end of the stacker for end loading of a pallet with vehicles. The lift bed or forks can be mounted on a lift truck supported from one or both ends along one side to transfer when operated parallel along an aisle.
