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.

Abstract: A hydraulic cylinder may include a housing and a rod extending from a working end positioned outside the housing through a rod end of the housing to a piston end positioned within the housing. The hydraulic cylinder may also include a piston arranged on the piston end of the rod and configured to articulate within the housing. The hydraulic cylinder may also include a cap end secured to the housing and having a pocket for receiving a sensor. The pocket may have a cylindrical sidewall. The cap end may include a bore extending therethrough and arranged generally tangential to the sidewall where the bore extends into the cap end, breaches the sidewall, and extends further passed the pocket. The hydraulic cylinder may also include a retention pin configured for placement in the bore and for an interference fit with the sensor when the sensor is arranged in the pocket.

Abstract: An electronic control module (ECM) on-board a machine executes a reduced-order model configured to generate virtual sensor data associated with a machine component based on sensor data measured by actual sensors. The ECM can also execute a machine learning model configured to generate offset data for the sensor data and/or the virtual sensor data, based on operating conditions, an age of the machine component, and/or other factors that the reduced-order model may not consider. The sensor data and/or the virtual sensor data, adjusted based on the offset data, can indicate whether the machine component has failed or is predicted to fail at a future point in time, and/or a remaining usable life of the machine component.
