A tensioning device for a wired energy or data transmission path includes a winding drum, a cable guide wire stored on the winding drum, and a spring accumulator. The winding drum is rotatable by an electrical drive for winding and unwinding the cable guide wire. The spring accumulator is operably exerting a resilient tensile force on a wire portion unreeled from the winding drum.

A wireless power transfer system 1 includes a power transmission device 2 and a power reception device 3. The power transmission device 2 is a power transmission device 2 installed in a road 4, is provided with a power transmission coil 21 that transmits power wirelessly, and is configured such that when installed in the road 4, the normal line of a coil plane of the power transmission coil 21 is inclined with respect to the normal line of the road surface of the road 4 in a lateral cross section of the road 4. The power reception device 3 is provided with a power reception coil 31 that receives power wirelessly, and at least a portion of the power reception coil 31 is housed in the wheel 6 of the moving body 5.

A controller for a trailer is disclosed. An example trailer controller assembly includes a force transducer that measures a force between a trailer and a towing vehicle connected to the trailer indicative of a difference in speeds between the trailer and the towing vehicle, and a controller communicatively coupled to the force transducer. The controller includes a brake controller that controls brakes of the trailer based on an input signal from the force sensor.

A method of measuring a reduction in energy consumed by an electricity network supplying a fleet of transport vehicles, said method comprising the following steps: sending (S1), over a period of time P, at least one activation signal to at least one energy saving device of at least one item of equipment, said activation signal being configured to alternatingly activate and deactivate said energy saving device over the period of time P; obtaining (S2) a signal of electrical power consumed over the period of time P by said electricity network; and deducing (S3) a reduction in energy consumed by said electricity network in response to said activation signal.

A current supply system of a team vehicle includes a towing vehicle operable in a cable-interconnected manner and an agricultural rear-mounted device coupled to the towing vehicle. The agricultural rear-mounted device has working equipment for performing a ground processing function. A base mast is allocated to the towing vehicle for producing a cable connection to a current supply interface of a first team vehicle that is travelling ahead, and an additional mast includes a further current supply interface allocated to the agricultural rear-mounted device for producing a further cable connection to a second team vehicle that is following. The additional mast is downstream of the working equipment of the agricultural rear-mounted device when viewed in a forward direction of travel of the team vehicle.

A work machine, such as a hauler at a mining site, includes a conductor rod housing concentric metal tubes for receiving electrical power from a contactor sliding on a power rail. A connection assembly includes lugs branching orthogonally from respective ones of the concentric metal tubes to an exterior of the conductor rod. The lugs include ball-and-socket joints configured to enable semi-spherical movement of the lugs at the exterior with respect to the joints. When attached to the contactor via conductive arms, the connection assembly provides multiple degrees of freedom for the conductor rod relative to the contactor and avoids detachment of the contactor from the power rail.

A system for electrically connecting a vehicle to track electrodes, the system comprising vehicle electrodes configured to be electrically connected with a respective one of the track electrodes; actuators operatively connecting the vehicle electrodes to a structure of the vehicle for displacement of the vehicle electrodes relative to the structure of the vehicle, the actuators operable to vary distances between the vehicle electrodes and the track electrodes; sensors operatively mounted to one of the vehicle or track electrodes, the sensors detecting variations in the distances; and a controller operatively connected to the actuators for actuating the actuators as a function of the variations in the distances detected by the sensors.
