  • Patent number: 10808362
    Abstract: A tamping unit for tamping a track has tamping tines which are designed for immersion into a ballast bed and which can be set in vibrations by a vibration drive. The vibration drive includes a housing in which a shaft including an eccentric is arranged for rotation about a shaft axis. A transmission element for transmitting a vibratory motion is mounted on the eccentric.

  • Patent number: 8245646
    Abstract: A dual tamper vehicle is provided. The dual tamper vehicle has a single articulated frame assembly having two sets of tampers. The articulated frame assembly is, essentially, a bifurcated vehicle having a forward, first vehicle and a trailing, second vehicle joined by a primary coupling having three axes of rotation. The primary coupling having three axes of rotation allows the two vehicles to roll, pitch, and yaw relative to each other thereby allowing the single, long rail bifurcated vehicle to travel over a railroad.

    Abstract: An exemplary apparatus and method for applying a force to rails of a track is disclosed. The apparatus has a device with at least one first weight and at least one second weight rotatably mounted about a horizontal shaft which has an axis which is essentially perpendicular to the longitudinal axis of the rails. A power source is provided to drive the rotation of the at least one first weight and the at least one second weight at different revolutions per second. The rotation of the at least one first weight and the at least one second weight creates a vertical force which has a larger downward component as compared to an upward component of the vertical force.

    Abstract: A drone vehicle for performing maintenance on a railway system is provided. A drone vehicle control system is structured to utilize tie position data to position a drone vehicle workhead over at least a portion of a respective tie. The drone vehicle control system is further structured to actuate the drone vehicle workhead. The drone vehicle may be controlled by a drone vehicle control system linked, preferably by wireless communications, to a lead vehicle and a lead vehicle control system. The lead vehicle control system and the drone vehicle control system are structured to communicate with each other, with the lead vehicle control system providing the tie position data to the drone vehicle control system.

  • Patent number: 7762197
    Abstract: A vibrating device having a flywheel rotatably disposed within a housing assembly. The housing assembly includes one or more openings therethrough structured to allow an effective amount of air to pass between the housing assembly enclosed space and the atmosphere. By exchanging an effective amount of air between the enclosed space and the atmosphere, the temperature within the housing assembly remains below the breakdown point of a lubricant used to reduce friction created when the flywheel is in use.

  • Patent number: 7383777
    Abstract: A track tamping machine has a machine frame extending in a longitudinal direction and tamping units mounted to the machine frame. A first or upper transverse guide extends in a transverse direction perpendicularly to the longitudinal direction. Two sliding blocks are mounted for displacement in the transverse direction independently of one another on the upper transverse guide. A second or lower transverse guide is positioned vertically below the upper transverse guide and parallel thereto. The lower transverse guide is mounted in the sliding blocks for displacement relative thereto in the transverse direction. Two inner unit frames are connected to a respective one of the sliding blocks and support a tamping unit in each case. Two outer unit frames are positioned in each case farther from a vertical machine center line—with regard to the transverse direction—than an adjacent one of the inner unit frames and support a respective tamping unit.

  • Patent number: 6978718
    Abstract: A tamping device and method of compacting ballast beneath the intersection of a railroad track's tie and rail utilize a pair of tamping units, each of which terminates in a tool blade. When a pair of tamping unit's first and second tool blades are in ballast on either side of the track's tie along one side of the rail, the first and second tool blades are moved in respective counter rotational first and second orbital paths such that forces generated in the ballast by the blades cooperate to compact the ballast beneath the intersection of the tie and the rail.

  • Patent number: 6805059
    Abstract: A tamping machine for tamping ballast underneath track ties includes a machine frame extending in a longitudinal direction and supported on the track by two undercarriages. Arranged between the undercarriages is a sub-frame which is supported on the track by a further undercarriage with a unit motive drive and connected to the machine frame by a frame support for displacement relative thereto in the longitudinal direction. A tamping unit and a track lifting unit are arranged on the sub-frame between the further undercarriage and the frame support. Operation of the unit motive drive to displace the sub-frame is assisted by an acceleration drive which is rigidly connected to the machine frame and has a piston end with a bracing plunger provided for temporary application to the sub-frame. A maximum stroke of the acceleration drive is shorter than a maximum displacement path of the sub-frame relative to the machine frame.
