Trolleytruck KTG-1 in Saint Petersburg, Russia
A trolleytruck (also known as a freight trolley or trolley truck[1]) is a trolleybus-like vehicle used for carrying cargo instead of passengers. A trolleytruck is usually a type of electric truck powered by two overhead wires, from which it draws electricity using two trolley poles. 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[2]) since trolleytrucks use tires that are insulators. Lower powered trucks, such as might be seen on the streets of a city, tend to use trolley poles for current collection. Higher powered trucks, such as those used for large construction or mining projects, may exceed the power capacity of trolley poles and have to use pantographs instead.[3][4] Trolleytrucks have been used in various places around the world and are still in use in cities in Russia and Ukraine, as well as at mines in North America and Africa. Because they draw power from the mains, trolleytrucks can use renewable energy sources – modern trolleytrucks systems are under test in Sweden and Germany along highways using diesel–electric hybrids to reduce emissions.
^In the United Kingdom a trolley may refer to the hand operated wheeled vehicle called a hand truck in North America. In North American usage the term trolley truck may also be used to refer to the wheelset or bogie that a streetcar rides upon.
^Trams may collect current from a single wire with a single trolley pole or pantograph and return the current to earth via the rail.
