  • Patent number: 5083892
    Abstract: An aerial weapons handling trailer includes a frame comprising longitudinally extending beams and a cross beam interconnecting the front ends of the longitudinally extending beams. The frame is supported on wheels which are pivotable between positions wherein the trailer is movable longitudinally and positioned wherein the trailer is movable laterally. The wheels include drive motors for positioning the trailer. A plurality of lift arms are pivotally supported on the longitudinally extending beams of the frame and in turn support lift beams. The lift arms include inwardly offset portions, and the lift beams are separated by a distance not greater than the width of a weapons package that is lifted and positioned by the trailer. The lift arms are actuated by hydraulic cylinders which are provided with load lock valves to prevent inadvertent lowering of the load carried by the lift beams.

  • Patent number: 4850786
    Abstract: A container handling apparatus (30) includes longitudinally extending primary frames (36, 38) and a cross frame (34) which interconnects the front ends of the primary frames. Lift masts (72, 74, 76 78) are mounted on the primary frame (36, 38) and extend upwardly therefrom. A load beam (80) is supported from the lift masts (72, 74, 76 78) and includes latching mechanisms (96) adapted for connection to a container. Secondary frames (50) are pivotally supported on the primary frames (36, 38) are in turn rotatably support driven wheel members (52). The pivotal relationship between the secondary frames (50) and the primary frames (36, 38) is regulated and controlled by spring/shock absorber/cylinder assemblies (54). The cross frame (34) is selectively retractable and the load beam (80) is selectively foldable to reduce the width of the apparatus.

  • Patent number: 4792272
    Abstract: A container handling apparatus having a pair of side frames and a cross frame. The apparatus also has four lift mechanisms for attachment to a container. Each lift mechanism is mounted on one end of a secondary lift arm. Four primary lift arms are connected to the side frames and to the midpoint of each of the secondary lift arms. A cam follower on the lower end of each secondary lift arm follows a cam horizontally along one of the side frames. Hydraulic cylinders rotate the primary lift arms about a pivot connection to the side frames. This causes the upper ends of the secondary lift arms to move vertically to raise and lower the lift mechanisms and the container. Transducers connected between the primary arms and the side frames equalize the amount of rotation of each of the primary lift arms and automatically keep the positions of the four lift mechanisms at the same height.

  • Patent number: 4702843
    Abstract: An adverse terrain vehicle is provided which includes a system for controlling a number of vehicular functions. The vehicle includes at least two variable displacement hydraulic motors, each for driving at least one wheel member on one side of the vehicle independently of the wheel members on the opposing side thereof. At least two variable displacement hydraulic pumps are mounted on the vehicle for supplying pressurized hydraulic fluid to the hydraulic motor on one side of the vehicle independently of the hydraulic motor on the opposing side thereof. The hydraulic pumps are driven by an engine. A sensor detects a decrease in the power output of the vehicle below that selected by the vehicle operator. Overload protection circuitry is responsive to the overload sensor and adjusts the displacement of the hydraulic motors and pumps to increase the power output capacity of the vehicle. Braking control circuitry coordinates with braking of the vehicle steering to effect turning of the vehicle while braking.
