A forged conveyor trolley bracket has head, arm and base portions bounded by sides, and a bent elbow formed in the arm portion medially of the head and base portions. A web, disposed centrally between the sides along the base and arm portions, has outer and inner faces. Projecting from the web outer face adjacent to the bracket sides are a pair of base portion reinforcing ribs and an outer pair of arm portion reinforcing ribs forming continuations of the base portion reinforcing ribs. An inner pair of arm portion reinforcing ribs project from the web inner face along the arm portion in opposed aligned relation with the outer pair of arm portion ribs; and, this inner pair of ribs extends from the base portion along the arm portion with a depth which increases to substantially equal the depth of the outer pair of ribs at the bent elbow, and which gradually decreases from the bent elbow to the head portion where the inner pair of ribs terminates. This configuration of the trolley bracket results in manufacturing economics and improved physical characteristics.
