A pantograph configuration for a vehicle has at least one pantograph embodied for at least temporary contact with an electrical network located externally outside the vehicle. The pantograph is movable from a contact position into a rest position. A first electrical network is located internally within the vehicle, which in the contact position is connected to the pantograph. A second electrical network located internally within the vehicle is connected to a ground or mass potential of the vehicle and in the rest position to the pantograph. In order to ensure that the pantograph is voltage-free in the rest position, the pantograph is connected to the first electrical network and the second electrical network in the rest position.

A vehicle is provided that connects to an power structure for powering and guiding the vehicle. The power structure includes a trolley, a track along which the trolley runs, a power source connected to the track, and a cable connected to the trolley and configured to attach to the vehicle moving on a surface. The vehicle includes a chassis and a cable connected to the chassis and configured to mechanically and electrically connect the vehicle to the power structure. The chassis includes a connector rotatable 360 degrees, and the cable connects to the chassis through the connector.

The present invention relates to a method for controlling an electrical power collector configured to collect electrical power from a track line of an electric road system arranged along a road. The track line comprising activatable light indicators arranged on the track line. The electrical power collector being mounted on a vehicle. The method comprising, while the vehicle is driving, capturing, using a camera mounted on the vehicle, a video stream depicting the track line, identifying active light indicators in the captured video stream, and upon identification of active light indicators, activating the electrical power collector such that a sliding contact of the electrical power collector makes sliding contact with the track line. Also a control circuit and a control system is presented.

A transportation system with a non-rail-bound, electrically or diesel-electrically driven vehicle, has a two-pole overhead conductor system with contact wires forming supply and return conductors. The vehicle has a current collector for the supply of electrical energy through sliding contact with the contact wires. A video detector on the vehicle determines a position of the contact wires relative to the vehicle. Marking elements mark the position of the contact wires. The video detector is oriented for taking video images of the marking elements, and an evaluation unit recognizes from a recorded video image whether contact wires are present above the vehicle and, when they are present, determines their position relative to the vehicle. Through the improved recognition of the position of the vehicle relative to the overhead conductor the operational safety of the transportation system is improved.

A modular structure supports elevated rail segments for delivering electrical power to a moving work machine, such as a hauler at a mining site. Opposite ends of a roadside barrier contain complementary tubular couplers arranged vertically, one having a first diameter supported by an arm and the other having a larger second diameter and a vertical slot. Couplers on adjacent barriers can be mated together concentrically along a central axis. The mated couplers help restrict longitudinal displacement, lateral displacement, slope change, and lateral rotation between adjacent barriers during placement. One barrier may be used as a temporary alignment structure to position barriers spaced alternatingly along a haul route for the work machine.
