  • Patent number: 9694997
    Abstract: A truck ramp including a first ramp element, second ramp element and pivoting structure located between the first and second ramp elements. The first ramp element is coupled to the truck at one end and at the other end, a hinge. The second ramp element is hinged at one end and at the other end interfaces with the ground or other surface. Between the first and second ramp elements is a pivoting structure comprised of a first component that is mechanically coupled to the first ramp element at the first hinged end and a second component that is mechanically coupled to the second ramp element at the hinged end. The first component and the second component are rotatable about an axis orthogonal to the first and second ramp element hinges.

  • Patent number: 5852978
    Abstract: The invention includes devices for displaying motor vehicles and to methods for displaying motor vehicles. In one aspect, the invention includes a device for displaying a motor vehicle comprising: a) a platform configured for supporting an unoccupied motor vehicle; and b) the platform being further configured for rotation about a rotation axis and tilting about a tilt axis while supporting the unoccupied motor vehicle. In another aspect, the invention includes a device for displaying a motor vehicle comprising: a) a first support member defining a tilt axis; b) a second support member defining a rotation axis; c) a platform pivotally supported by the first and second support members and configured for supporting a motor vehicle, the platform being configured for tilting about the tilt axis and for rotating about the rotation axis; and d) a power source operationally attached to at least one of the first support member and the platform and configured for driving the tilting of the platform about the tilt axis.

  • Patent number: 4941794
    Abstract: As automated loading/unloading system is shown, which uses a lift truck 10 for loading and unloading cargos and adpated to travel between a container 90 and a coneyor 50, a rotatably disposed turntable 60 for rotation about a vertical axis, the turntable being rotated when the lift truck 10 is on top thereof so as to turn the lift truck to face the container 90 or conveyor 50. A transport passage 80 installed between the turntable 60 and container 90 to permit the lift truck 10 to reach the container 90. An external power unit 100 is employed for controlling the lift truck and the turntable 60. Guide rails 70 and 81 are provided to extend along the turntable 60 and the transport passage 80 along one edge. The lift truck 10 is designed so as to urge its body to one side in its movement so that the movement of the lift truck is guided by the rails 70 and 81 and the inside wall of the container on the same side of the rails.

  • Patent number: 4796537
    Abstract: The invention provides a sturdy substantially rectangular scow-like turntable platform with retractable wheels for mobility and turntable mechanics for the use of heavy trucks. The turntable platform is towable and can be used with wheels down or with wheels retracted for bottom surface friction stabilization. A trailer is provided with powering devices and controls for operating the turntable motor and the various ram activated devices. The turntable motor and the rams can be powered by pressurized hydraulic fluid or by compressed air.

  • Patent number: 4776735
    Abstract: A railroad flat car having a rotatable loading floor for transferring loads between it and a platform. A sleeve is provided in the rotatable loading floor which slidably receives a beam coupled to the chassis. The beam is extended into the sleeve to secure the loading floor in its stowed position during travel. The beam abuts against a steel plate in the sleeve to provide a solid buffer against horizontal motion of the rotatable loading floor along its longitudinal axis, the beam and sleeve also stiffen the rail car to minimize sagging under heavy loads. The end of the loading floor has a pinion gear which meshes with a toothed rack on the chassis. A motor turns the pinion gear to swing the rotatable loading floor into position.

  • Patent number: 4457656
    Abstract: Stack handling apparatus includes an input delivery section having two spaced apart conveyor segments operatively arranged to move equidistantly with respect to a centerline between the two conveyor segments. A stack formation section receives articles conveyed in a serial stream from the input delivery section and includes a carriage having a blade apparatus which is maintained at a generally constant predetermined angle as the carriage is transported in a closed loop transport movement path. Articles are assembled into batches on the blade apparatus, and each batch is transferred to door gate apparatus by relative linear movement. The door gate apparatus releases the batch for linear free fall movement to a turntable mechanism of a stack delivery section. The turntable mechanism alternately rotates 180.degree. after the receipt of each batch. Longitudinally extendable hydraulic assemblies are eccentrically connected to rotate the turntable mechanism.
