Abstract
An automatic loader and unloader for an elevator includes a stationary frame, a main carriage movable in either direction relative to the stationary frame, and a coupler carriage movable in either direction relative to the main carriage. The main carriage is slidably disposed on the stationary frame by a bearing arrangement which provides a cantilever support for the main carriage when the main carriage is extended. The main carriage and the coupler carriage are extended and retracted by two pair of cables. One pair of cables effects movement of the main carriage and coupler carriage in one direction, and the other pair of cables effects movement of the main carriage and coupler carriage in the other direction.
