A GANTRAY FRAME IS CARRIED ON A TRACK EXTENDING LONGITUDINALLY OF THE STORGE CONVEYOR AND MOUNTS AN ELEVATOR HAVING AN OPERATOR''S PLATFORM THEREON. THUS, THE GANTRY FRAME MAY BE MOVED TO A POSITION ALONG THEY TRACK AND THE ELEVATOR RAISED TO A SELECTED LEVEL SO THE OPERATOR CAN SELECT ARTICLES FROM THE STACK AND LOWER THE ELEVATOR TO DEPOSIT THE ARTICLES SO SELECTED ON THE STORAGE CONVEYOR FOR EVENTUAL CONVEYANCE TO SAID COLLECTING POINT. RAMP-TYPE PICKER CONVEYORS MAY BE MOUNTED ON THE ELEVATOR FOR RECEIPT OF THE ARTICLE PICKED AND FOR ACTUATION WHEN THE ELEVATOR IS LOWERED TO TRANSFERED THE SELECTED ARTICLES TO THE STORAGE CONVEYORS. A LIFTING FORK MAY BE MOUNTED ON THE ELEVATOR FOR TRANSVERSE MOVEMENT THEREON WHEREBY THE GANTRY RAME MAY BE MOVED TO A POINT AT ONE END OF THE STACK AND THE FORK ACTIVTED TO LIFT A PALLET LOADED WITH ARTICLES ONTO THE ELEVATOR, THE GANTRY FRAME THEN MOVED TO A SELECTED POSITION ALONG THE STACK AND THE ELEVATOR RAISED AND, FINALLY, THE FORK AGAIN ACTIVATED TO TRANSFER THE LOADED PALET TO A SELECTED POSITION IN THE STACK.
