Abstract: Systems and apparatuses an adjustable platform rail assembly. The adjustable platform rail assembly includes a lower rail assembly and an upper rail assembly. The lower rail assembly extends away from a platform of a mobile elevated work platform to define a passenger compartment therein. The upper rail assembly is coupled to the lower rail assembly and extends upwardly away from the lower rail assembly. The upper rail assembly includes a perimeter space assembly and a confined space assembly. The upper rail assembly is movable between (a) a first configuration in which the perimeter rail assembly and the confined space assembly are extended and the upper rail assembly surrounds the passenger compartment, and (b) a second configuration in which the perimeter rail assembly is collapsed, the confined space assembly is extended, and the upper rail assembly surrounds a subset of the passenger compartment.

Abstract: Systems and apparatuses an adjustable platform rail assembly. The adjustable platform rail assembly includes a lower rail assembly and an upper rail assembly. The lower rail assembly extends away from a platform of a mobile elevated work platform. The upper rail assembly is coupled to the lower rail assembly and extends upwardly away from the lower rail assembly to define a passenger compartment therein. The upper rail assembly is coupled to the lower rail assembly and is movable between a first position where the upper rail assembly defines an upper perimeter defined by a first length and a second position where the upper rail assembly defines an upper perimeter defined by a second length that is shorter than the first length.
