Abstract:
A handrail assembly for a tank trailer and a yoke assembly for the same. Handrail assembly provides a safety device for an operator walking along a top wall of the tank trailer. The handrail assembly includes a top rail, a plurality of vertical members, a safety wire and, sometimes, a bottom rail. Each yoke assembly secures one of the top and bottom ends of the vertical members to either of the top and bottom rails or to a mounting bracket on the tank. Each yoke assembly includes a base member engaged partially in a bore of the vertical member, and a cradle member engaged with an exterior wall of the top or bottom rails or mounting bracket. Base and cradle members are secured together by a pivot pin. Fluid-actuated cylinders extending between the vertical members and the tank move the handrail assembly between collapsed and expanded positions.
