A rail unit includes an upper plate segment extending in a width direction, a lower plate segment extending in the width direction and at a position in a downward direction from the upper plate segment, and an intermediate plate segment extending in a vertical direction and joining an edge of the upper plate segment in a first width direction and an edge of the lower plate segment in a first width direction. A power feeder is located in a space defined by the upper plate segment, the intermediate plate segment, and the lower plate segment in the rail unit. The upper plate segment includes a traveling surface facing in an upward direction. The lower plate segment includes a lower flat portion extending in a traveling path direction and the width direction, and a groove protruding in the downward direction from the lower flat portion and extending continuously in the traveling path direction.

The present application shows a trolley system for providing electrical power to a vehicle, the trolley system comprising: a trolley line that is at least one out of: a flexible structure to be loosely positioned on a ground surface; and a sealed structure with an insulating housing comprising a sealing arrangement for sealing an opening extending along the trolley line, and a current collector assembly mounted on the vehicle for establishing a sliding electrical contact with a conductor of the trolley line.

Electrified roadway systems include a roadway, and vehicles configured to operate on the roadway. The roadway has a base, and two electrically-conductive rails mounted on the base. One of the rails is electrically connected to a source of electric power, and the other rail is electrically connected to an electrical ground. The vehicles include non-electrically-conductive tires, and an electric motor mechanically connected to, and configured to rotate at least one of the tires to propel the vehicle along the roadway. The vehicles draw electric power from the roadway via two electrical pickups that contact the respective rails, and a retracted position at which the pickups are out of contact with the rails. A wear-resistant cover can be positioned on each of the rails. The wear resist covers can have features that maximize the contact area and the contact force between the covers and the rails.

A direct current (DC) traction power electric arc suppressing device is provided. The device comprises a parallel resistor-capacitor (RC) circuit electrically connected between a main traction power rail and an associated power rail incline end section with a narrow insulating joint installed between the main traction power rail and the associated power rail end section incline.

In a method for producing different rail variants from an assembly set, and system having a vehicle which is movable on a rail part, the assembly set includes a rail profile part and two different reactive components, and the rail profile part includes an interface at which one of the different reactive components is optionally able to be connected.

A current collector for electrically supplying an electrical load which is movable along a conductor line. The current collector has a fastening element and at least one sliding contact with an elongate sliding contact surface, which extends in a longitudinal direction, for sliding contact with an electrically conducting line profile, which extends in the longitudinal direction, of the conductor line. The sliding contact is articulated on the fastening element at spaced apart fastening regions, so as to be movable in a feeding plane extending parallel to the longitudinal direction by means of two articulated lever arrangements. A resetting device acting on the articulated lever arrangements and on the fastening element is provided which, when the sliding contact is deflected from an inoperative position, in which the sliding contact surface preferably extends substantially parallel to the longitudinal direction, moves the sliding contact back into the inoperative position.

This invention relates to a portable, lightweight, non-conductive, and non-flammable hard lightweight cover that is placed over a third rail and used to protect workers from being electrocuted while working near live powered third rail system. Further, the third rail railway cover board may be highly visible and made to work in all weather conditions. Because of the simplicity of installation, no special power expert is needed to install the third rail railway cover board which will save a great deal of time and safety. The third rail railway cover board may include one or more of the following features: lightweight, non-conductive, and flame retardant; placed over high voltage third rail; weather and rain resistant; high-visibility; stackable; locking mechanism from one cover to an adjacent cover; LED light holder; contoured shape to fit all US third rail systems; and water shed design.
