A pick-up apparatus and a container are specially designed to facilitate the lifting of the container and the dumping of its contents. The container includes a frame which has tubular frame members extending between the top and bottom of the container, and a cover is hingedly mounted on the top of the container and can be releasably latched in a closed position by an inertia latch. The pick-up apparatus includes a boom, a pick-up arm mounted on the boom for articulation in a generally horizontal plane, and a pair of clamping arms mounted on the end of the pick-up arm. The clamping arms are slidably mounted on the pick-up arm, and the spacing between the arms can be varied by hydraulic cyinders on the pick-up arm. Each of the clamping arms includes a clamping pad which includes a plurality of flexible, resilient cone-shaped projections which are sized and spaced so that the tubular frame members of the container can be received between the ends of adjacent projections.
A container and pick-up assembly comprising in combination a container and a pick-up apparatus, the container having a top and bottom and a plurality of tubular members between the top and bottom, the pick-up apparatus having a pick-up arm, means for raising and lowering the pick-up arm, a pair of clamping arms movably mounted on the pick-up arm for movement toward and away from each other, means for moving the clamping arms toward and away from each other, each of the clamping arms having a plurality of spaced-apart flexible and resilient projections mounted thereon and extending toward the other clamping arm, the spaced-apart projections on each clamping arm providing grooves therebetween for receiving the tubular members on the container whereby the container may be lifted by positioning the container between the clamping arms and moving the clamping arms toward each other to clamp the projections thereon about the tubular members of the container.
