1. A monitoring system for monitoring stability of an articulated boom and pipeline concrete placing system, the articulated boom and pipeline system including an articulated boom for supporting the pipeline having a bottom end rotatably connected to a base and a leading end which is maneuverable with respect to the bottom end, the base further including at least one extendable outrigger, the monitoring system comprising:

  • a boom position sensor, including a global positioning system (GPS) receiver mounted at the leading end of the boom, for providing boom position information from which a horizontal and vertical location of the leading end of the articulated boom can be determined;

    an outrigger sensor for sensing a position of the outrigger with respect to the base, wherein the outrigger sensor supplies an outrigger signal representative of the sensed outrigger position; and

    a controller for receiving the boom position information and the outrigger signal, and for determining stability of the articulated boom assembly based upon the boom position information, the outrigger signal, a known weight of the articulated boom and pipeline, a known weight of the pipeline, and a known weight of a material contained in the pipeline.
