Above: the largest of the K3 series was the 10-cubic meter 100S

    Wolfgang Knierim specialized in refuse equipment at the small-end of the scale for urban collection and small-volume satellite operations. The Knierim K3 rear loader was produced circa 1980-1995 and used the Japanese Kyokuto Press-Packer system. This unusual packer mechanism is of the slide-sweep type, but has its sweep panel operated by large external cylinders acting against a linkage assembly and passing through curved slots in the hopper side walls. The slide panel is operated conventionally by two in-line cylinders within the tailgate. Available in 4, 6, 8 to 10 cubic meter sizes, it featured an advanced curved-shell body, foreshadowing a body construction method now applied to virtually all rear loaders. Bin lifts to 1,100 liter capacity were offered with the K3.

The K3 is easily identified by the large slots in the sidewalls for operating the sweep panel
