ABSTRACT:
A trolley or carriage assembly for conveyors, including overhead and in-floor conveyors, in which the inner race of a wheel assembly, a shield or seal for the wheel, and a support for supporting a work piece to be transported by the trolley or carriage assembly are simultaneously locked against rotation with respect to each other and a supporting and retaining shaft by the non-circular outer circumference of the shaft and corresponding non-circular apertures of the inner race, shield or seal and support. Preferably the shaft is a hexagonal, headed bolt or rivet which may include a relubrication passageway for use in closed, sealed wheels. The assembly provides better load distribution, easier assembly in and disassembly from conveyors, and longer, more durable and wear-resistant operation, especially with stamped, sheet metal trolley brackets.
