Abstract

A boom system for a concrete-delivery device includes a plurality of booms which are pivotably interconnected. At least one of the booms has a recess along its length, the recess configured to at least partially receive an adjacent boom when the boom system. is in a retracted position. Side walls of the boom are extended to define the recess in the form of a channel. The recess may have a depth greater than or equal to a height of the adjacent boom so that the adjacent boom is received within the recess when the boom system is in the retracted position. Alternatively, the recess may have a depth less than a height of the adjacent boom so that the adjacent boom is only partially received in the recess when the boom system is in the retracted position.
