  • Patent number: 5064333
    Abstract: In an apparatus for emptying containers, particularly refuse containers, the lifting and tipping frame (111) present the container (106) to be emptied is actuated by means of a pressure medium power circuit. This apparatus possesses, inter alia, an electrical control device (70) to activate the pressure medium power circuit, an actuating device (72) for activating the electrical control device (70), and also a switch device (92, 94) for affecting the lifting and tipping motion of the lifting and tipping frame (111), wherein the switch device is actuated by the container (106) received on the lifting and tipping frame. This apparatus is distinguished in that the switch device (92, 94) is operative for the further lifting and tipping motion only after initiation of the lifting and tipping motion, and the actuating device is a switch element (72) to be operated independently of the switch device.

  • Patent number: 4722658
    Abstract: A loading apparatus for emptying containers into a common receptacle comprises a pick-up attachment and pick-up support for the containers to be emptied, which is further structured and improved, so that the pick-up attachment and the pick-up support are mounted with a limited movability on a dump frame of the loading apparatus in order to be movable toward the container to be picked up and from the properly deposited container. As the container is raised from its location, the pick-up attachment and the pick-up support are structured so as to be brought into a standard position with respect to the dump frame and are restrained in this standard position. The operations can be observed or also automatically controlled by electrical container contacts operated by the container and mounted on the pick-up attachment and the pick-up support.
