摘要:
A container, such as a transfer trailer (10) that can be transported, has expandable side walls (24, 24'). The walls are hydraulically forced outward to increase the inside width dimension of the container. A loading device can then be backed into the container whereby solid material waste can be directly loaded into the container. Once the container has been loaded, the side walls can be retracted to their original positions, such that the container maintains its standard regulated width dimension.
