摘要： A reversible shelf type vertical conveyor wherein a plurality of shelves are pivotally mounted between two endless chains that are driven by pairs of upper and lower sprockets, the shelves pivoted to a space saving vertical orientation during the return run and to a horizontal orientation during the working run. Positive control of the orientation of shelves is provided by pairs of rollers attached to the shelves which straddle a guide bars during the return run and ride within guide channels during the working run. During the transition between return and working runs at the top and bottom, shelves are held tight against bosses adjacent the sprockets. Each successive cycle pivots the shelves 180 degrees, and the shelves are symmetrical about their pivot axis.
