Metso Railcar positioner - rack and pinion

Track grade, curve and indexing speed are the most prominent factors influencing positioner system design.

Metso’s rack and pinion positioner handles:

• Maximum train weights up to 31,000 tonnes (34,000 tons US)
• Pulling forces up to 177 kilogram-force (390,000 lbf. US)
• Hauling speed up to 0.75 m/s (2.5 ft/s US)

When combined with our railcar dumper, the complete system provides fast dependable train turnaround requiring only one operator.

• Faster cycle times due to more accurate car spotting.  No rope stretch.
• Additional drives can be added to the carriage in the future should trains with heavier railcars result in additional pulling force requirements.
• Less foundation requirements by eliminating the off-board rope drive foundation.

• The train positioner may work in conjunction with train holding devices, such as a holding arm, wheel clamps or wheel chocks.
