Abstract: A system for measuring load, from a cable, associated with a boom of a pipelayer is disclosed. The system includes a linkage configured to be coupled between a boom block, engaged with the cable, and a portion of the pipelayer. In addition, the system includes a load cell coupled between the linkage and the boom block for measuring the load, from the cable, on the linkage. A measurement load path, of the load cell, is aligned with a load path, of the load, between the boom block and the linkage.

Abstract: A system for determining a lifting capacity of a pipelayer is provided. The system includes a load sensor configured to generate a signal indicative of a load suspended from a lifting hook, an angle sensor configured to generate a signal indicative of an angular position of a chassis relative to ground surface, a boom position sensor configured to generate a signal indicative of a position of a boom relative to an undercarriage, and a counterweight position sensor configured to generate a signal indicative of a position of a counterweight relative to the undercarriage. The system further includes a controller configured to receive the signal from each of the load sensor, the angle sensor, the boom position sensor, and the counterweight position sensor. The controller is also configured to determine the lifting capacity of the pipelayer based, at least in part, on the received signal.
