  • Patent number: 11511976
    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.
    Type: Grant

  • Patent number: 8924115
    Abstract: The disclosure describes, in one aspect, a control system for controlling a braking system. The control system includes a parking brake operatively to at least one wheel, a park brake override mechanism operatively associated with the parking brake, an inching pedal operatively coupled to a transmission, a shift lever operatively coupled to the transmission, at least one sensor operatively coupled to the parking brake to detect when the parking brake is engaged, at least one sensor operatively coupled to the inching pedal to detect a depression of the inching pedal, and at least one sensor operatively coupled to the shift lever for detecting at least one of a forward or reverse gear selection. The control system further includes a controller operatively coupled to the at least one sensors to receive corresponding signals and adapted to control the engagement of the parking brake when the inching pedal is depressed and the at least one of the forward or reverse gear selections is desired.
