SHUTTLE STOPPER

Various devices, assemblies, components, systems, and methods are provided relating to a shuttle stopper to facilitate alignment of a shuttle with a rail. An example shuttle stopper may include an alignment portion defining an alignment surface configured to face inwardly towards a center axis of the rail. The alignment surface may define a first distance to the center axis. The shuttle stopper may further include a safety portion defining a safety surface configured to face inwardly towards a center axis of the rail on an opposite side of the center axis from the alignment surface. The safety surface may define a second distance to the center axis. The second distance may be greater than the first distance. The shuttle stopper may be configured to rigidly attach to the rail.
