Abstract:
An industrial machine that includes a dipper, a crowd actuation device, a hoist actuation device, a swing actuation device, one or more sensors, and a controller. The one or more sensors generate one or more signals related to a load within the dipper. The one or more signals are received by the controller. The controller determines, based on the one or more signals, whether the industrial machine is operating in an over-loaded condition by comparing a suspended load to a suspended load threshold value. If the suspended load is greater or equal to the suspended load threshold value, the controller takes an action to control the industrial machine. The action taken by the controller can include increasing, decreasing, or otherwise modifying a speed parameter or speed limit, increasing, decreasing, or otherwise modifying a force parameter, etc.
