Devices, systems and methods for engaging and disengaging railcar wheels and for controlling travel of railcar

摘要

Devices, a system and a method for controlling travel of a railcar along a set of rails are provided, the railcar having wheel treads that ride on the rails. A railcar stop is selectively movable between a first position wherein the railcar is free to travel along the rails, and a second position wherein the railcar stop is configured to engage the tread of the at least one of the wheels to thereby stop and prevent travel of the railcar in at least a first direction along the rails. The railcar stop is further configured to be selectively movable in the first direction along the rails from the second position to a third position to thereby disengage the railcar stop from the tread of the least one of the wheels.

主权项

1. A device for controlling travel of a railcar along a rail structure, the railcar comprising wheels having treads that ride on the rail structure, the device comprising:
a railcar stop that is selectively movable by a first drive arrangement between a first position wherein the railcar stop is disengaged from the rail structure and the tread of at least one of the wheels so that the railcar is free to travel along the rail structure, and a second position wherein the railcar stop is engaged with the rail structure, and configured to engage the tread of at least one of the wheels to thereby stop and prevent travel of the railcar in at least a first direction along the rail structure; wherein the railcar stop is configured to be selectively movable by a second drive arrangement independent of the first drive arrangement and slidable on the rail structure in the first direction from the second position to a third position wherein the railcar stop is disengaged from the tread of the at least one of the wheels.
