A boom apparatus comprises a boom structure, at least one flexible line, a fluid cylinder, and a barrier. 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.

1. A boom apparatus, comprising: a boom structure comprising a first boom and a second boom attached pivotally to the first boom, the second boom having a first, longitudinal dimension, a second, lateral dimension, and a third dimension, the first, second, and third dimensions perpendicular to one another,at least one flexible line extending along the boom apparatus relative to the first dimension,a fluid cylinder attached pivotally to the first boom and the second boom to pivot the second boom relative to the first boom, the fluid cylinder comprising an end portion pinned to the second boom,a barrier positioned between the end portion and the second boom relative to the third dimension, the at least one flexible line routed externally of the second boom through a passageway positioned between the barrier and the second boom relative to the third dimension such that the barrier spaces the at least one flexible line apart from the end portion so as to prevent abrasion of the at least one flexible line by the end portion during pivotal movement of the second boom relative to the first boom,a monolithic anchor body fixed to the second boom, the anchor body comprises: a hinge point, the hinge point and the end portion are included in a hinge of the boom apparatus so as to be pinned to one another, andthe barrier. 2. The boom apparatus of claim 1, wherein the anchor body is a casting. 3. The boom apparatus of claim 1, wherein the hinge point comprises a first barrel and a second barrel, the end portion is positioned between the first barrel and the second barrel relative to the second dimension, and the hinge comprises a pin positioned in the first barrel, the second barrel, and the end portion. 4. The boom apparatus of claim 3, wherein the second boom comprises a first lug and a second lug, the first and second barrels and the end portion are positioned between the first and second lugs relative to the second dimension, and the pin is positioned in a hole of the first lug and a hole of the second lug. 5. The boom apparatus of claim 1, wherein the barrier is positioned between the hinge point and the second boom relative to the third dimension. 6. The boom apparatus of claim 5, wherein the barrier comprises a first barrier portion and a second barrier portion, and the hinge point is positioned between the first and second barrier portions relative to the first dimension. 7. The boom apparatus of claim 1, wherein the anchor body comprises a frame, the hinge point and the barrier are mounted to the frame, and the frame is fixed to the second boom. 8. The boom apparatus of claim 7, wherein the frame mates with the second boom. 9. The boom apparatus of claim 7, wherein the second boom comprises a first boom side wall and a second boom side wall spaced apart from the first boom side wall relative to the second dimension, the frame comprises a first frame side wall and a second side frame wall spaced apart from the first frame side wall relative to the second dimension, the first boom side wall comprises a first lug, the second boom side wall comprises a second lug, the first frame side wall is mounted to the first lug, the second frame side wall is mounted to the second lug, and the hinge point and the barrier are mounted to the first and second frame side walls. 10. The boom apparatus of claim 9, wherein the hinge point comprises a first barrel and a second barrel, the hinge comprises a pin positioned in the first barrel, the second barrel, and the end portion positioned between the first barrel and the second barrel relative to the second dimension, the first barrel is mounted to the first frame side wall, and the second barrel is mounted to the second frame side wall. 11. The boom apparatus of claim 10, wherein each of the first frame side wall and the second frame side wall is generally triangle-shaped, the first barrel provides a vertex of the first frame side wall, and the second barrel provides a vertex of the second frame side wall. 12. The boom apparatus of claim 11, wherein the second boom comprises an intermediate boom wall attached to and positioned between the first boom side wall and the second boom side wall relative to the second dimension, the frame comprises a support wall mounted to the intermediate boom wall and attached to a first edge of the first frame side wall opposite to the vertex of the first frame side wall and to a second edge of the second frame side wall opposite to the vertex of the second frame side wall. 13. The boom apparatus of claim 12, wherein the support wall is H-shaped. 14. The boom apparatus of claim 10, wherein the barrier comprises a generally C-shaped first barrier portion and a generally C-shaped second barrier portion, the first and second barrels are positioned between the first and second barrier portions relative to the first dimension, and each of the first and second barrier portions comprises a post extending lengthwise in the second dimension, a first arm extending from the post and attached to the first frame side wall and the first barrel, and a second arm extending from the post and attached to the second frame side wall and the second barrel. 15. The boom apparatus of claim 14, wherein the hinge point comprises a first barrel and a second barrel between which the end portion is positioned relative to the second dimension, the hinge comprises a pin positioned in the first and second barrels and the end portion, the barrier comprises a first barrier portion and a second barrier portion, the first and second barrels are positioned between the first and barrier portions relative to the first dimension, and the first and second barrier portions are positioned between the support wall and the first and second barrels relative to the third dimension. 16. The boom apparatus of claim 9, wherein the second boom comprises an intermediate boom wall attached to and positioned between the first boom side wall and the second boom side wall relative to the second dimension, the frame comprises a support wall mounted to the intermediate boom wall and attached to the first frame side wall and the second frame side wall, and the first and second frame side walls, the support wall, and the barrier cooperate to define the passageway. 17. The boom apparatus of claim 7, wherein the frame comprises a first frame side wall, a second frame side wall, and a support wall attached to the first and second frame side walls, the hinge point and the barrier are mounted to the first and second frame side walls, and the barrier is positioned between the support wall and the hinge point relative to the third dimension. 18.
