摘要

A side-bar chain has chain links each formed of a stack of side bars and chain pins traversing aligned side bar openings in the side bars of each stack transversely to the chain length; and a plurality of chain braces each formed by opposite outermost side bars of at least some of the chain links and a transverse web joining the brace-forming side bars to one another and straddling the side bar stack transversely to the chain length. Each brace-forming side bar includes a longitudinal web extending parallel to the chain length between the side bar opening and the transverse web. The transverse web of each chain brace has an aperture for reducing a cross-sectional dimension of the transverse web measured parallel to the chain length at least adjacent the longitudinal web of each brace-forming side bar. The transverse web has an outer width dimension which is measured parallel to the chain length and which is substantially equal to a length dimension of the brace-forming side bars, measured parallel to the chain length.
