ABSTRACT:
A handrail for an aircraft belt loader in which a pair of parallel support arms pivotally support a rigid rail member with a variable-length link converted to be non-parallel with the support arms when the handrail is erect or operative. When the handrail is collapsed, the link is shortened and a compression spring inside of the link is further compressed so that maximum erecting force is applied when the handrail is stowed.
