the rail is commonly secured to the cross-tie by a clip or clamp mechanism, but may also be fastened by spikes, screws or bolts driven into the cross-tie through holes in the tie plate.the upper surface of the tie plate has either one or a pair of parallel, vertically projecting ribs or shoulders that define a cradle area or rail seat for receiving the rail.Tie plates generally comprise a flat steel plate with a substantially flat bottom that rests on the cross-tie and distributes the axle load over a wider area.the rails are fastened to the cross-ties through tie plates to maintain the track gauge or spacing of the two rails.Rail track generally consists of two parallel steel rails that are supported on a series of wooden sleepers or cross-ties that are perpendicular to the rails.the present invention relates to railroad equipment for “maintenance of way” operations and, in particular, to equipment for the automated detection of spike killed cross-ties and extraction of railroad spikes.E01B29/26- Fixing or removing detachable fastening means or accessories thereof Pre-assembling track components by detachable fastening means the fastening means being spikes.E01B29/24- Fixing or removing detachable fastening means or accessories thereof Pre-assembling track components by detachable fastening means.E01B29/00- Laying, rebuilding, or taking-up tracks Tools or machines therefor.E01B- PERMANENT WAY PERMANENT-WAY TOOLS MACHINES FOR MAKING RAILWAYS OF ALL KINDS.E01- CONSTRUCTION OF ROADS, RAILWAYS, OR BRIDGES.B61K9/08- Measuring installations for surveying permanent way.B61K9/00- Railway vehicle profile gauges Detecting or indicating overheating of components Apparatus on locomotives or cars to indicate bad track sections General design of track recording vehicles.B61K- AUXILIARY EQUIPMENT SPECIALLY ADAPTED FOR RAILWAYS, NOT OTHERWISE PROVIDED FOR.G01N3/08- Investigating strength properties of solid materials by application of mechanical stress by applying steady tensile or compressive forces.G01N3/00- Investigating strength properties of solid materials by application of mechanical stress.G01N- INVESTIGATING OR ANALYSING MATERIALS BY DETERMINING THEIR CHEMICAL OR PHYSICAL PROPERTIES.Status Abandoned legal-status Critical Current Links SECURITY INTEREST (SEE DOCUMENT FOR DETAILS).
