The boom structure comprises a first boom and a second boom attached pivotally to the first boom. The at least one flexible line extends along the boom apparatus. The fluid cylinder is attached pivotally to the first boom and the second boom. The fluid cylinder comprises an end portion pinned to the second boom. The barrier is positioned between the end portion and the second boom. The at least one flexible line is routed externally of the second boom through a passageway positioned between the barrier and the second boom such that the barrier spaces the at least one flexible line apart from the end portion.
