Abstract
The present invention has its application to a vehicle-related arm-shaped contact means (()) related to a contact means arrangement as a current collector or system ('S') for propelling an electrically, i.a. by batteries ('II', B), propellable vehicle () along a roadway () comprising “a” a plurality of roadway portions (), wherein said road portions are allotted at least one track or slit (), having introduced therein current supplyable conductors (), and “b” one or more powerable vehicles (), with each vehicle exhibiting a control circuit (, “R”) adapted for necessary distribution of power, wherein said vehicle () is on its underneath side provided with a displaceable contact means (()) as said current collectors. Said current collector (') is shaped as a main portion (), made of an electrically insulating material, and having a lower surface () facing towards the contact surface (′) being shaped flat, and having a lower contact surface () consisting of an electrically conductive material (). The electrically conductive material () is adapted to extend through the main portion () for forming one or more upper contact surfaces () and/or connecting conductors ().
