Abstract: A system for controlling operation of a winch assembly having an electric motor, a drum, and a cable. A controller is configured to access a winch load threshold, with the winch load threshold defining a hold zone and a reel zone, and one of the hold zone and the reel zone including loads greater than the winch load threshold and another of the hold zone and the reel zone including loads less than the winch load threshold. The controller is further configured to determine whether the drum is rotating, determine whether the winch assembly is operating within the hold zone or the reel zone, generate a hold current while the winch assembly is operating within the hold zone preventing rotation of the electric motor, and generate a reel current while the drum is operating within the reel zone permitting rotation of the electric motor.

Abstract: A system for controlling a winch assembly having a hydraulic motor, a drum, a cable, and a cable tension sensor. A controller is configured to access a winch load threshold defining a hold zone and a reel zone, and one of the hold zone and the reel zone including loads greater than the winch load threshold and another of the hold zone and the reel zone including loads less than the winch load threshold. The controller is further configured to determine whether the winch assembly is operating within the hold zone or the reel zone, and generate a zero flow command while the winch assembly is operating within the hold zone to prevent rotation of the hydraulic winch motor, and generate a pressure differential command while the rotatable winch drum is operating within the reel zone to permit rotation of the hydraulic winch motor.

Abstract: A visual indication system for a machine is provided. The visual indication system includes an output module configured to be displayed at an external location relative to an internal portion of a cabin of the machine and configured to provide a visual indication viewable. The visual indication system also includes a controller communicably coupled to the output module. The controller is configured to receive a signal indicative of a parking status and an implement status of the machine. Further, the controller is configured to determine a locked state associated with the parking status and the implement status. The controller is configured to transmit the visual indication of the determined locked state to the output module.
