CONTROLLING THE OPERATION OF AN INDUSTRIAL MACHINE BASED ON WIRE ROPE DEAD WRAPS
Abstract:
An industrial machine that includes a dipper, a hoist drum, a wire rope connected between the hoist drum and the dipper, a hoist motor, a sensor, and a controller. The sensor generates a signal related to a number of wire wraps of the wire rope around the hoist drum, which is received by the controller. The controller determines, based on the signal from the sensor, the number of wire wraps around the hoist drum. If the controller determines that there are an insufficient number of dead wraps around the hoist drum, the controller sets one or more parameters of the hoist motor. The controller sets each of the one or more parameters of the hoist motor to a value that is lower than a normal operational value for the parameter.
