A mining shovel includes a dipper assembly comprising a dipper arm coupled to a dipper, a boom assembly configured to support the dipper assembly, and an overcrowd prevention system including one or more sensors configured to monitor an axial force. The mining shovel also includes a swing abuse prevention system, including one or more sensors configured to monitor one or more compound loading forces, and one or more sensors configured to monitor a torsion loading force. The mining shovel also includes a control module configured to receive signals from the sensors, and to control at least the crowding force applied to the dipper.
