Two current collectors are required in order to supply and return current, because the return current cannot pass to the ground (as is done by streetcars on rails) since trolleytrucks use tires that are insulators. Lower-powered trucks tend to use trolley poles for current collection, while higher-powered trucks, such as those in large-scale construction or mining, may exceed the capacity of trolley poles and use pantographs instead.
