A chain or series of trolleys having horizontal axles is supported in an upwardly opening track. A pendant has an incurved bearing surface that rests on one of the axles. A bent support arm is secured to an upwardly extending post of the pendant and supports a load. The pendant is pivotable on the axle to maintain the post in a generally vertical attitude. An arcuate slot in the pendant receives a transverse pin on the chain to prevent inadvertent vertical movement of the pendant. The pendant is removed from the axle by tilting the pendant and lifting the pendant from the axle.
