Abstract
A crane-mounted concrete pumper has been provided wherein a telescoping boom assembly is pivotally and rotatably mounted on the platform of the truck. A concrete conduit is positioned in the interior of the boom assembly and has its intake end operatively connected to a concrete pump mounted on the truck by means of a flexible concrete hose. An extension boom is pivotally mounted on the boom assembly and may be pivoted from a folded, inoperative position to an extended position. A concrete conduit is provided in the interior of the extension boom and is placed into communication with the concrete conduit in the boom assembly when the extension boom is in its extended position. The crane may be either used to pump concrete or used in a conventional fashion. An aerial platform is provided on the boom assembly to enable an operator to pump or spray concrete.
