Controlling a power system in a mining truck includes receiving data indicative of an expected change in suitability of the mining truck for on-trolley operation, and outputting a control command to an actuating mechanism for a pantograph responsive to the data and prior to occurrence of the expected suitability change. A first electrode is formed on a substrate. The present slide-out tube overcomes the deficiencies of conventional slide-out tubes by driving the slide-out section in a smooth, uniform, even manner while providing a low profile. The method further includes charging a fee to an appropriate account for the selected coverage type and amount.
