<p><P>PROBLEM TO BE SOLVED: To provide a stacking cart for transportation a plurality of which can be stacked vertically and kept in storage or moved efficiently when the cart is not used or moved in an empty state. <P>SOLUTION: An automatic course control condition making system includes a base frame 1 which has moving casters 4 attached to the lower part of four corners of the frame 1 and has a square shape in a plan view, an upper frame which has a square shape smaller than that of the base frame 1 in a plan view and has load bearing corner frames 5 with ribs bearing four corners of the bottom of a load on four corners of the upper frame 2, and support members 3 which support the upper frame 2 to keep it almost parallel with the base frame 1 at a given level from the floor. The upper frame 2 and the base frame 1 are analogous to each other and are located to have the identical center in a plan view. The upper frame 2 is given such an outline dimension that allows stacking of carts in such a way that the moving casters 4 at four corners of the base frame 1 of an upper cart overhangs above the upper frame 2 of a lower cart. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
