Abstract: A current collector for a non-rail-bound, electric traction vehicle has an articulated support linkage, which, on the contact wire side, supports rocker assemblies with contact strips and, on the vehicle side, has a base joint for articulation to the traction vehicle. A pneumatic reciprocating drive is coupled to the support linkage for raising the rocker assemblies from a lower parking position into an upper contact position when the reciprocating drive is pressurized and for lowering into the parking position under its own weight when depressurization occurs. An exhaust air line connects the reciprocating drive to the environment to lower the rocker assemblies. An air accumulator and a downstream throttle valve are connected between the reciprocating drive and an environment opening of the exhaust air line. The rocker assemblies can be quickly lowered and nevertheless brought into the parking position without damage in order to disengage the current collector.

Abstract: A method and a device test whether there is contact between a current collector and a contact wire of an overhead line. The current collector is located on a motor vehicle driven by an electric motor, and the contact wire extends in a direction of travel. The current collector has two contact regions oriented transversely to the direction of travel which are arranged one behind the other in the direction of travel and on each of which an end contact element is located. A pair of end contact elements located on the same side is connected to a measuring device and an electrical state variable is detected by the measuring device. Subsequently, it is determined in accordance with the detected state variable whether the pair of end contact elements is in contact with the overhead line.

Abstract: A non-rail-bound, electrically driven vehicle contains a vehicle body having a vehicle width and a current collector for feeding traction energy from an overhead line. The current collector has two support brackets, an apex member connected to overhead-contact-line-side ends of the support brackets and lying transversely to a longitudinal axis, and two rockers mounted so as to rotate about an apex member axis. The support brackets are articulated at their vehicle-side ends to the vehicle body such that the rockers can be adjusted in height between a lowered idle position and a raised contact position and can be transversely moved between two lateral deflected positions. Accordingly, the rockers can be moved transversely independently of one another, wherein it is possible to adjust a current collector width so that it is less than the vehicle width. Therefore the vehicle can also be licensed for operation outside electrified routes.

Abstract: An apparatus for conveying mail flats in an upright position with at least one conveying module has a circulating, horizontally oriented floor belt guided via return rollers, and two endless lateral guide belts guided via deflection rollers. A distance of the lateral guide belts from one another at ends of the conveying modules is greater than a thickest mail item. A height of a first lateral guide belt is less than that of a second lateral guide belt. Below the first lateral guide belt an elastic, narrow, endless pressure belt is provided, which is resiliently pressed against a lower part of the second lateral guide belt by pressure deflection rollers and pressed away from the second lateral guide belt by the mail items according to their thickness. Guide rails are mounted obliquely to a conveying direction and tangentially to the pressure deflection rollers.

Abstract: A device for orienting flat mail items with a u-shaped conveying channel has a base belt guided over reversing rollers and driven at a predetermined speed. First and second guiding belts are driven at the predetermined speed and guided over deflection rollers. A flat mail item is transported over a defined path standing on its narrow side. The first guiding belt is inclined as a lateral reference belt for frictional orientation of the mail items and guided via fixed deflection rollers. The second guiding belt is guided by pression deflection rollers so that the conveying channel possesses a defined minimum channel width to orient thin mail items on the base belt. For the mail items located in the conveying channel, the second guiding belt deviates against a spring force of a deflection roller bearing, with the second guiding belt possessing a lower coefficient of friction than the lateral reference belt.
