Abstract
Abstract A hand cart for stacking goods, such as cartons, beverage sixpacks, etc., includes a vertical extending carrying space that is defined by a back main frame member, two vertical side structures, and a bottom platform structure, with the bottom platform structure being inclined relative to the horizontal so as to define with the back frame member an included angle less than 90*. In addition, the back main frame is inclined relative to the vertical whereby packaged goods stacked on the hand cart are prevented from toppling, and the goods are interlocked in such manner that the packages must be removed in a desired sequence from the stack of goods.
