摘要:
A system of treating installed railroad ties, comprising a conveyance vehicle configured to move along a railroad track, one or more drill carriages slidably attached to the conveyance vehicle to drill one or more holes at predetermined locations in the railroad ties, an air dispenser configured to deliver a blast of air proximate the one or more holes sufficient to remove debris from and around the one or more holes, a preservative dispenser configured to deliver a predetermined amount of preservative material into the one or more holes, and a plug dispenser configured to deliver a plugging material to the one or more holes to seal the preservative material in the one or more holes.

Systems and methods are provided for submersion of wood products, specifically stacked railroad crossties, in an ambient temperature and pressure dip such as a borate solution. The systems and methods are designed to provide for treatment of stacked green railroad crossties with a borate solution in a batch methodology as part of a continuous crosstie processing operation for manufacture of such crossties.
摘要:
An end plating machine comprising a frame having an in-feed portion at one side thereof and an out-feed portion at the other side thereof. A stationary platen is provided at opposite ends of the frame below the in-feed and out-feed portions adapted to support the ends of a cross-tie delivered thereto. A conveyor delivers the cross-ties to the in-feed portion whereupon a tie transporter assembly moves the tie from the in-feed portion and delivers the tie to a tie elevator assembly which lowers the tie onto the stationary platens. A robotic claw assembly is provided above the stationary platen for squeezing the ends of the tie to close cracks therein. Each pair of robotic claws is operated by a single hydraulic cylinder. When the ends of the tie are squeezed together by the robotic claws, a hydraulic ram at opposite ends of the tie drives nail plates into the ends of the tie. After the plates have been driven into the tie, the robotic claws disengage from the tie and the tie is raised upwardly from the stationary platens to the out-feed portion. The cycle is then repeated.
摘要:
Apparatus for pressing nailing plates or the like into opposite ends of elongate members, such as railroad ties, thereby to end-plate the ties. The apparatus comprises a press and apparatus for conveying the ties forwardly one after another in generally horizontal position with the ties extending transversely with respect to the direction of conveyance to a first station, and for feeding the ties one at a time from the first station to a second station where each tie is end-plated. The conveying apparatus, which comprises a series of walking beam units, is also operable to discharge a tie from the second station after it has been end-plated.

摘要:
Apparatus and methodology are disclosed pertaining to selecting from a stockpile of used and discarded ties those which can be restored for a second use, removing accumulated scale from the selected used ties, redimensioning the selected ties to a usable smaller size, filling and sealing tie end cracks with a suitable filler, transversely compressing the ties to substantially close the adhesive-filled cracks, applying a permanent fastener to retain the compressed state of the closed and sealed tie cracks and externally treating the fastened ties with pesticide and anti-rotting composition or compositions.
