Motor grader protection of wire harnesses

Abstract:

A protection system for a wire harness in a motor grader includes a controller and a sensor. The controller has a processor executing stored commands and a datastore with memory architecture containing stored angular orientation values for the circle frame. The sensor is coupled to one or more of the circle frame, the draft frame, and a circle actuator that rotates the circle frame relative to the draft frame. The sensor is configured to detect an angular orientation of the circle frame relative to the draft frame. The controller is configured to: receive input signals from the sensor indicating the angular orientation of the circle frame relative to the draft frame; query the datastore for a maximum angular orientation value of the circle frame; and terminate actuation of the circle actuator when the circle frame is at the maximum angular orientation value.
