PURPOSE: To efficiently land cargos by suspending a tray elevator body from an end of a jib to be freely turned and attaching a belt conveyer for horizontal transportation to this jib to transfer the cargos from said body to the belt conveyer.

CONSTITUTION: Carton boxes (cargos) 14 are transported to a receiving conveyer 15 under a tray elevator body 8 suspended from an end of a jib 1 to be turned through a bearing 9 by a turning unit 10 and sequentially scooped up by trays 12 attached to an endless chain 11 of said body 8 to be vertically upward moved in said body 8. Next, the carbon boxes 14 are transported to a horizontal belt conveyer 7 attached to the jib capable of turning and elevating of a tray elevator type unloader for landing. When the carton boxes 14 in a ship around the located receiving conveyer 15 are exhausted, said body 8 and jib 1 are turned right and left by a proper angle to land again the carbon boxes 14 around them.
