  • Patent number: 4780033
    Abstract: A railroad freight car having a rotatable loading floor for transferring loads between it and a station platform. The railroad station has two platforms on opposite sides of the rail car. An edge of each platform is provided at each longitudinal end with a sloping beam which angles upwardly from the end of the platform towards its center. The lowest part of the beam, which is at the free end of the platform, is below a set of wheels carried on the chassis of the rail car. The center portion of the platform is at a height above that of these rollers. The rollers are arranged to extend laterally of the rail car and to overlie the beams. As the rail car pulls into the station, the rollers will engage the upwardly sloping part of the beams to thereby raise the chassis in relation to its wheels by virtue of extending the suspension as the car continues in its direction of movement.

  • 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: 4718810
    Abstract: A high-speed, bidirectional transporter for a multiple station production line provides for the programmable pickup, transport and delivery of materials at non-sequential work stations along the production line. The transporter is self-propelled by a rack and pinion drive and moves along a track that defines a course through the multiple work stations. A turntable on the transporter carries an extensible and retractable arm whose motion, when coupled with a materialladen pallet, provides for either the pickup or delivery of a pallet to or from an individual work station. Coupling and uncoupling of the arm with a pallet is effected by the controlled rotation of the turntable, which is capable of 180 degrees of rotation to also impart to the transporter the ability to transfer pallets off of both sides to address a work station on either side of the track.

  • Patent number: 4684314
    Abstract: A pipe handling apparatus is adapted for transferring oil well pipe to and from a drilling rig. The apparatus includes a transportable chassis having tracks for supporting and guiding a reciprocable and rotatable table. A first scissors lift mounted to the table provides vertical motion to a platform to which is mounted a second scissors lift. The second scissors lift is designed to impart vertical and horizontal motion to a conveyor. The conveyor comprises three axially spaced endless belts for moving the pipe longitudinally to the conveyor takeoff point. Tapered spades protrude into the spaces during the pipe return operation to eject the pipe from the conveyor. The conveyor and platform are reciprocable with respect to the second and first scissors lifts, respectively. The chassis includes pivotable arms for raising a pipe to the top of the collapsed scissors lifts so that a pipe rolls onto the conveyor belts prior to lifting.

  • Patent number: 4676171
    Abstract: A turntable for turning vehicles, including a base member adapted to be supported on a flat floor and having a platform rotatably disposed above the base member for supporting a vehicle thereon. Rollers are utilized to reduce friction and support the platform as it rolls around and the rollers roll along the floor. The roller mechanism and actuating mechanism are extremely compact in order to allow the turntable to be low enough to the floor so that ramps are not needed to get a vehicle thereon and tipping is not required. A rod is pivotally attached to the underside of the platform and has a cog operatively attached thereto with a free end thereon for engaging a first or second cog holding mechanism attached to each side respectively of the base member.
