  • PANTOGRAPH ASSEMBLY WITH FORCE DAMPENERS
    Publication number: 20240025261
    Abstract: 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.
