  • Extending boom construction
    Patent number: 3979873
    Abstract: A plurality of telescopic triangular cross sectioned booms slide within one another so that they can be extended and retracted and they are adapted to support conduits for pumping concrete or other material from one location to another. Angulated flanged corner constructions support the booms for sliding movement one with the other and in one embodiment, wheeled trolleys or bogeys are secured to the corners to reduce the frictional load between adjacent boom sections.
