Patent number: 5083892Abstract: 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.Type: GrantFiled: January 17, 1989Date of Patent: January 28, 1992Assignee: Standard Manufacturing CompanyInventors: Norman D.

Patent number: 4792272Abstract: 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.Type: GrantFiled: March 2, 1987Date of Patent: December 20, 1988Assignee: Standard Manufacturing Company, Inc.Inventors: Norman D. Oswald, Carl M. Franklin, Marc H. Gutzler, Harry S. Mankey

Patent number: 4702843Abstract: 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.Type: GrantFiled: June 21, 1985Date of Patent: October 27, 1987Assignee: Standard Manufacturing Co., Inc.Inventors: Norman D.
