In a vertical conveyor arrangement for the transport of catering service goods in an aircraft with at least two decks arranged one above another, catering service goods are transported from a lower deck embodied as a freight deck into an upper deck. A conveyor arrangement is embodied according to the invention as a lift carriage, whereby the lift carriage is made up of a top structure with guide elements that are operatively connected with guide rails arranged above the freight deck, and a bottom structure that protrudes into the freight compartment in transport position, and that, for receiving a receptacle, comprises at least one cantilever arm reaching over the top side of the receptacle, a column element, side arms at least partially encompassing the sides of the receptacle, as well as a floor plate. The bottom structure forms a secured receiver for the receptacle.It is especially advantageous, through avoidance of a fixed lift installation in the freight compartment, not to hinder the throughgoing passability of the freight compartment in the loading with containers. Moreover, a reliable and continuous secure fixing of the transport receptacle is ensured during the lift operation.
