Abstract: A method and apparatus for embossing the sidewalls of heavy gauge sheet metal containers involves clamping over a top edge of an opening into the container using a press carrying complementary embossing dies. The clamping apparatus can be a portable punch press having opposite members on a solid C-shaped frame, one being movable by a hydraulic drive cylinder to bear against the other. The die set coupled to the clamping apparatus has opposite protrusions and depressions representing an indicia to be embossed on the container, such as a trademark, symbol, owner's name or other indicia. In one embodiment the container is a dumping refuse container with an opening edge reinforced by a frame. The press has an opening throat that spaces the dies sufficiently that the clamping apparatus can be clamped over the reinforced edge to space the point of deformation of the sheet metal from the edge of the opening.

Abstract: A plural container trailer has hydraulic systems for loading, unloading, and otherwise handling removable containers. The trailer has a bed long enough to carry two containers in line. The trailer has an undercarriage carrying a rear tilt frame. A forward mounted cable and winch system operates over the rear tilt frame to pull a first or forward container from the ground fully to a front docking position on the trailer bed. The forward cable remains connected to the forward container and it is not necessary to disengage a rear pulling mechanism and recouple the container to a front pulling mechanism. A second container-hoisting system loads and unloads a second container between the ground and the tilt frame. A slider mechanism engages against the front wall of the first container, and is moved forward as the first container is moved toward the front docking position.
