Abstract
An apparatus and method for forming a container to have a desired weight by using interchangeable sidewalls of different weights while holding contents therein. The apparatus uses a pair of cast iron end walls and a pair of cast iron sidewalls that are fastened together and to a bottom steel plate. The pair of cast iron sidewalls are available in different thicknesses to provide different sidewall weights in order to form a container of the desired weight. The operator can interchange the sidewalls if a different container weight is later required. Each sidewall has an upstanding handle on its top surface and each end wall has a handle in its top edge. The length of the interchangeable sidewalls is typically greater than the length of the end walls, whereas the heights of the interchangeable sidewalls and the end walls are identical.
