ABSTRACT:
A movable bulkhead for partitioning a truck body or the like is pivotally supported on an overhead shaft. The shaft extends transversely between a pair of trolleys which ride along tracks and are capable of differential movement thereon. A second pair of trolleys are also track mounted to support a spring-loaded counterbalance mechanism for the bulkhead. Drum and cable assemblies included in the counterbalance mechanism automatically pivot the bulkhead to a raised position when the seal of the bulkhead against the flow of the truck is broken.
