  • Patent number: 8079799
    Abstract: A lifting apparatus is adapted for use in lifting a container having a pair of channels, each of the channels having a pair of open ends. The lifting apparatus includes an elongated support bar and a hook assembly mounted on each end of the support bar. Each of the hook assemblies includes a pair of hooks and a hydraulic cylinder and piston for rotating the hooks between open and closed positions. The container is lifted by lowering the support bar with the hooks in the open position until the hooks can be rotated into the open ends of the two channels. The hooks are then rotated to the closed position so that the hooks extend into the channels. The lifting apparatus is then raised to lift the container.

  • Patent number: 7866934
    Abstract: A loading device can be mounted quickly and easily to a roll-off vehicle by mounting a yoke assembly to the frame of the roll-off vehicle. The yoke assembly includes a pair of attaching potions which extend from the vehicle, and each of the attaching portions is provided with an opening. A pair of hydraulically actuated hooks are pivotally mounted on the loading device. The loading device is pulled onto the roll-off vehicle so that the hooks are adjacent the attaching portions of the yoke assembly. The hooks are then pivoted to extend through the openings in the attaching portions so that the hooks are secured to the attaching portions.

  • Patent number: 7353652
    Abstract: A control apparatus is provided for operating six hydraulic valves from two different positions. The control apparatus is particularly suitable for operating the hydraulic controls of a six function trash loader. First and second three-function joysticks are mounted at the first position, and third and fourth three-function joysticks are mounted at the second position. A first set of three rotatable rods extends between the first and third joysticks, and a second set of three rotatable rods extends between the second and fourth joysticks. Each joystick includes a handle which is movable along a first axis for rotating a first rod of one of the sets, along a second axis for rotating a second rod of the set, and about a third axis for rotating a third rod of the set. A crank arm on each of the six rods is connected to one of the six hydraulic valves so that rotation of each of the rods operates one of the valves.
