Abstract

A wagon or trolley which is especially suited for the transport and distribution of piles of cartons or parcels of various sizes which are stacked directly on top of each other, comprising a substantially rectangular bottom and four mutually connected walls. A first wall is pivotally connected with the adjacent wall and serves as a door, the first wall being adapted to swing about a vertical axis so as to offer unrestricted loading access to the loading zone of the wagon when in open position. A second wall is provided with an upper door portion which in a removed or lowered position provides an additional access opening to the contents of the wagon without increasing the outer dimensions of the wagon, the lower portion of the second wall being permanently connected to its adjacent side walls and offering necessary safety for the objects in the wagon to be kept in position when the upper door portion of the second wall is opened. A third wall is made adjustable in the lateral direction so as to vary the size of the wagon depending on the floor space occupied by the pile of cartons or parcels to be held and transported in the wagon.
