Patent number: 6805059Abstract: 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.Type: GrantFiled: July 11, 2003Date of Patent: October 19, 2004Assignee: Franz Plasser Bahnbaumaschinen-Industriegesellschaft m.b.H.Inventors: Josef Theurer, Friedrich Peitl

Publication number: 20040144282Abstract: A machine for the treatment of a track extending in a longitudinal direction comprises a first machine frame and a second machine frame which are mobile on the track on undercarriages and detachably connected to one another by means of a coupling. A bridge girder, extending in the longitudinal direction and comprising lifting devices, has a first end connected to the first machine frame for rotation about a vertical axis. A second end of the bridge girder is supportable on the second machine frame and displaceable relative thereto in the longitudinal direction with the aid of guide means. By detaching the coupling, the first and second machine frames can be spaced from one another so far that rail segments may be placed upon the track by means of the lifting devices.Type: ApplicationFiled: January 16, 2004Publication date: July 29, 2004Inventor: Bernard Huwer

Patent number: 6725782Abstract: A railroad test vehicle extending in a longitudinal direction comprises a measurement axle comprising two flanged wheels rotatable about a measuring axis extending transversely to the longitudinal direction and adapted to run on two track rails. A cross member extends transversely to the longitudinal direction, is vertically spaced from an underside of the vehicle and is affixed thereto. The connection between the measurement axle and the cross member comprises two trunnions transversely spaced from each other and mounted on the cross member, each trunnion defining a clearance with the cross member sufficient to enable the trunnion to be freely tilted to either side of the vehicle about an axis extending in the longitudinal direction, a support frame mounted on each trunnion for pivoting freely about an axis extending perpendicularly to the longitudinal direction, and two pairs of linkages, the pairs being transversely spaced from each other by the same distance as the transversely spaced trunnions.Type: GrantFiled: March 24, 2003Date of Patent: April 27, 2004Assignees: Franz Plasser Bahnbaumaschinen-Industriegesellschaft m.b.H, Ensco, Inc.Inventors: Jeffrey A. Bloom, Gary A. Carr, Georg Seyrlehner, Ta-Lun Yang, Günther W. Oberlechner

Patent number: 6698358Abstract: A machine picks up ties from a ballast bed of a track while advancing continuously in an operating direction. A machine frame carries a tie transport unit onto which a tie pick-up device transports the ties. The pick-up device has tie skids immersed in the ballast bed for supporting the ties to be lifted. The tie skids are extended backward by a tie sliding track on which the underside of the ties is supported and the ties are slid to the tie transport unit. The tie sliding track extends in the longitudinal direction and it has a transfer end at which the ties are transferred to a receiving end of the tie transport unit. An endless transporting chain with tie engaging members shifts the ties from the ballast bed to the receiving end of the tie transport unit. The transporting chain has a lower deflection end that lies ahead of its upper deflection end and it extends along a reference line that encloses an acute angle with the ballast bed.Type: GrantFiled: June 13, 2003Date of Patent: March 2, 2004Assignee: Franz Plasser Bahnbaumaschinen-Industriegesellschaft mbHInventors: Josef Theurer, Manfred Brunninger
