Abstract: 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.

Abstract: A top drive horizontal carousel for a full height carrier including generally horizontal and coextensive upper and lower guides and associated upper and lower support assemblies. The upper and lower support assemblies include a series of guidance points or carrier pins which define a first vertical plane for each of the carriers. The support assemblies are attached to the back of a corresponding carrier via horizontally directed extensions which cross the first vertical plane. The back of the carrier forms a second vertical plane, outwardly disposed from the first vertical plane, allowing the carrier to extend above the upper guide and below the lower guide to provide for a carrier whose height is not limited by the space between the upper and lower guides.
