Abstract
An automated warehouse system row cart includes a lifter that uses cams to raise and lower pallets. Three symmetrical cam lobes are cut into a hollow cylinder. Three matching cam lifters ride these lobes and are attached to an elevator plate. A stepper motor running in one direction is used to raise and lower the elevator plate by virtue of the action between the cam lobes and lifters.
