Abstract: The invention relates to a telescopic arm (1), in particular, for a current collector system for a vehicle which can be driven along a power rail arrangement, wherein the telescopic arm (1) can be extended and/or retracted by means of an adjustment drive (7, 8, 9, 10) and the telescopic arm (1) has a base unit (2) which can be attached to the vehicle, on which a first telescopic stage (3) is arranged displaceably in a direction (RT), in particular, horizontally, and a second telescopic stage (4) is arranged displaceably on the first telescopic stage (3) in the same direction (RT), wherein the adjustment drive (7, 8, 9, 10) is arranged on the first telescopic stage (3), characterized in that the adjustment drive (7, 8, 9, 10) interacts with a rigid chain (S), which is connected with its one end (Sa) to the base unit (2) and with its other end (Sb) to the second telescopic stage (4).

Abstract: The invention relates to a current collector system (1) for a vehicle (F) which can be moved in a longitudinal direction along a power rail arrangement (S) having at least one current collector trolley (3) and current collector contacts (5) arranged on this, which current collector contacts can be connected to the power rails (ST) of the power rail arrangement (S) and a telescopic arm (2) which can be fixed or is fixed to a vehicle (F), which telescopic arm can be extended and/or retracted by means of an adjustment drive, characterised in that the adjustment drive has at least one rigid chain arrangement (9) which is driven by at least a first rigid chain drive (8).

Abstract: The invention relates to a positioning zone (EB) for a travel path (1), wherein the travel path (1) has at least one guide rail (2, 3) and the guide rail (2, 3) is used to guide a current collector trolley (11), provided with current collector contacts (12), of a current collector system (10) arranged on a vehicle which can move along the travel path (1), and the travel path (1) has at least one travel path conductor bar (5), wherein the current collector trolley (11) can be moved horizontally and vertically to the travel path (1) in the positioning zone (EB) by a positioning device of the current collector system (10), characterized in that at least one further conductor bar (5?) is arranged in the region of the positioning zone (EB) or at least one travel path conductor bar (5) extends and/or is extended into the positioning zone (EB) beyond at least one guide rail (2, 3) of the travel path (1).
