Abstract
A chain and hydraulic motor-driven low dog railcar indexer is disclosed which is operable along a curved track section. The system includes left and right track side indexing railcar-moving arrangements, each of which includes an indexer track and a chain-return trough. The indexer tracks and chain return troughs are segmented to accommodate the curved railroad track section and wear pads are provided to enable chain operation in the curved section.
Claims9
A railcar positioning system for a curved railroad track comprising:
- (a) a pair of spaced trackside railcar-moving arrangements operable along a curved railroad track section one positioned outside and parallel to each rail of a railroad track including a curved railroad track section, each said railcar-moving arrangement further comprising:
- (1) a segmented trackside guideway indexer track located next to one of the railroad rails wherein said guideway indexer track comprises a plurality of sequentially angled connected indexer track sections extending along said curved railroad track section;
- (2) a dog carriage mounted for operation along said guideway, said dog carriage carrying at least one pusher dog mounted on said carriage;
- (3) a continuous chain connected to operate said dog carriage along said guideway indexer track, said chain having an associated segmented return trough that comprises a plurality of sequentially angled connected trough sections extending along said curved rail section;
- (b) a hydraulic power unit including a hydraulic motor connected to reversibly drive said chain;
- and
- (c) a control system associated with said power unit for controlling the operation of said positioning system such that said positioning system may be operated as an indexer.
