The invention relates to a device for fastening a sliding element to a current collector or to a rocker mounted there, to draw electrical energy from an overhead contact line to an electrically driven vehicle. The device comprises a sliding element, a carrier, and a carbon contact piece arranged on the carrier, and a fastening point for fastening the sliding element to the current collector is formed between the sliding element and the current collector. At each fastening point between the sliding element and the current collector, a detent means is arranged on the side of the sliding element and, for each detent means, a receptacle for said detent means is arranged on the side of the current collector, wherein each detent means and the receptacle associated therewith are releasably brought into engagement with each other by inserting and locking the detent means in the receptacle.

A current collector for a non-track-bound, electrically driven vehicle for feeding electrical energy from a two-pole overhead line system with two contact wires. Two upper arms are rotatably connected to an adjustable lower arm by toggle joints. Each upper arm carries a contact rocker for contacting the contact wires. Coupling bars are rotatably connected to the upper arms and articulated so that adjustment of the lower arm forces adjustment of the upper arms. A compensating rocker compensates for a height difference between the contact rockers with a rocker stand and a rocker beam. The rocker stand can be rotatably connected to the vehicle and the rocker beam is connected to the coupling bars by way of compensating joints on either side of the rocker joint. At least one stop element limits a rotational movement of the rocker beam about a rocker joint axis of the rocker joint.

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 device for measuring force and for monitoring wear on overhead lines includes a force-measuring system which includes two contact bars which, in an operating state, are oriented at a right angle to an overhead line to be monitored, and two connection bars, which, in the operating state, are oriented parallel to the overhead line. A bar-shaped force transducer is fastened to each end portion of the two connection bars and each of the bar-shaped force transducers extends in an axial direction of the respective connection bar.

There is proposed a boom apparatus or boom head assembly being attachable to an electric or hybrid vehicle. The boom apparatus, comprising first and second poles being alignable with the respective wires of an overhead power line system, and respective boom head assemblies coupled to the first and second poles, including a collector configured to abut the first wire. The boom head assemblies each including a respective movable guide, comprising opposing wings that are positioned on either side of a respective collector, being configured to aid in the alignment of the collector with a respective wire. The connecting pole assembly, together with the connecting pole stowage mechanism applies equally to a single wire catenary and connecting pole application as would be the case of a conventional tram.
