Just thought I’d mention that the chains in those man-lifts serve as guides/protection for the hydraulic and electrical cables that reside inside them. They carry comparatively little force, but are designed to accommodate the changing length of the boom as it telescopes.

So is it the blue-painted beam that carries most of the force?
