A conveyor chain consisting of metal chain links each having a rectangular conveying surface and a hinge loop system situated under the conveying surface, comprising a centrally located hinge loop on one side of the chain link and two spaced hinge loops located opposite thereto, the central loop being located between the spaced loops of an adjacent chain link and being connected therewith by means of a hinge pin, the central loop being capable of hinging freely about the hinge pin which is fitted in the spaced loops with a clamped fit. According to the invention, the loadability of the chain can be increased by at least 25% when the ratio between the width of the central loop and the sum of the widths of the two spaced loops is approximately 0.9 and when the total hinge width is in the range of 54 to 60 mm and the hinge pin diameter is between 6.15 and 6.55 mm.
