Vertical hi-rail device

A hi-rail device comprising:

• a mounting assembly for mounting on a vehicle;
• an axle assembly for holding wheels;
• a locking slot, the locking slot comprising a first locking end and an opposed second locking end forming opposite ends of the locking slot, the locking slot extending continuously from the first locking end to the second locking end, the locking slot having contours;
• a locking pin movable in translation within the locking slot, the locking pin being captured within the locking slot, and traveling only confined within the contours of the locking slot which guide the locking pin from the first locking end to the second locking end;
• one of:
• a linkage connected to the mounting assembly and for connection to an axle assembly for holding wheels, the linkage being foldable and unfoldable to translate the axle assembly relative to the mounting assembly, the mounting assembly having the locking slot;
• and
• a linkage connected to the axle assembly and for connection to a mounting assembly for mounting on a vehicle, the linkage being foldable and unfoldable to translate the axle assembly relative to the mounting assembly, the axle assembly having the locking slot;
• and
• a locking cylinder connected to the locking pin, the locking cylinder comprising a spring to urge the locking pin into an abutting surface of any one of the first locking end and the second locking end when the locking pin is in any one of the first locking end or the second locking end, thereby locking the linkage,
• wherein the locking cylinder extends from the linkage to the locking pin, the locking cylinder comprising the spring to urge the locking pin into the abutting surface of any one of the first locking end and the second locking end when the locking pin is in any one of the first locking end or the second locking end, thereby locking the linkage.
