A pantograph assembly includes one or more force dampeners. When the pantograph is in a lowered position, the force dampeners absorb forces imparted onto the pantograph assembly by the movement of a work machine to which the pantograph assembly is installed. Additionally, in some examples, the pantograph assembly includes a support frame that provides structural rigidity to an A-frame.

A control system includes an interface device having a body extending between a first end and a second end and that provides power to a vehicle system from an external power source. Sensors may be coupled with the interface device and detect sensor data associated with the coupling of the external power source with the interface device. A controller receives the sensor data from the sensors and determines a coupling location at which the external power source is coupled with the interface device. The coupling location may be at a first position between the first end and the second end of the interface device. The controller controls movement of the vehicle system to change the coupling location between the external power source and the interface device from the first position to a second position between the first and second ends of the body.

A road-guided motor vehicle includes a power collector for an overhead line and an actuator arrangement. The power collector is controlled by the actuator arrangement from a first, pantograph-lowered into a second, pantograph-raised position or vice versa. The power collector is assigned a sensor arrangement having a data connection to a control unit of the actuator arrangement. The control unit is configured such that a contact pressure of power collector against overhead line is detected or determined using sensor arrangement data, a memory with spatially resolved contact pressures for the power collector and a position ascertaining unit. At a motor vehicle position determined by the position ascertaining unit, an associated contact pressure is read out from the memory and automatically set by the control unit or signaled to a motor vehicle driver. A method for raising a power collector pantograph onto an overhead line is also provided.

A power supply device for a vehicle, in particular for a utility vehicle such as an electric bus or an electric heavy goods vehicle, includes at least one contact head that can be brought in contact with a docking apparatus to establish an electrical connection, and includes at least a first pivot arm that is connected to the at least one contact head and can be rotatably connected to a vehicle, and includes a return apparatus, where the return apparatus is formed, as a driver with respect to the at least one first pivot arm, to be placable on the at least first pivot arm and removable from the at least first pivot arm such that a safe return of the first pivot arm is ensured.
