A current collector for a multi-pole contact line system has a lower arm that is pivotally mounted on a base and at least two upper arms that are pivotally mounted on an end of the lower arm opposite the base. The current collector also has at least two contact assemblies that are arranged on the respective upper arms and are associated with separate different poles of a contact line. The current collector further has a central compensating rocker arranged on the base and at least two connecting rods, the first end of each of which is pivotally connected to the central compensating rocker and the second end of each of which is pivotally connected to one of the at least two upper arms. An electrified transport system uses such a current collector.

A vertical sorter having a track with at least two straight portions and at least two curved portions is disclosed. A linear motor primary coil is mounted on the at least two straight portions, and two adjacent straight potions are connected by at least one curved portion. Supply tables are disposed at ends of the at least two straight portions respectively and used for providing goods to each straight portion; chutes are disposed along two sides of the at least two straight portions and used for transporting the goods on each straight portion to corresponding areas; a sorting trolley is used for conveying the goods on the supply table to a corresponding chute; and a secondary magnet is mounted on the sorting trolley, wherein the linear motor primary coil and the secondary magnet cooperate to drive the sorting trolley to move along the track.

A busbar for a conductor line for supplying electrical power to an electrical load which can be moved along the conductor line. To reduce the wear on the busbar and the sliding body that slides along the conductor line by decreasing the friction between these two components, a busbar, on which the surface of the side of the busbar intended to make contact with a sliding body of a current collector has at least one groove-shaped depression, which, at least in certain sections, runs at an oblique angle relative to the longitudinal direction of the busbar, with the longitudinal direction defined by the intended direction of movement of the sliding body.
