  • Patent number: 11174618
    Abstract: A payload detection system for automated payload tip-off of a loading operation includes a tip-off controller. The tip-off controller is configured to receive a signal of a remaining payload target; receive a signal of a material weight within an implement and a signal of an angle of the implement; and determine a tip-off threshold based on the material weight and the remaining payload target. The tipoff controller initiates a bulk dump sequence if a difference between the material weight and the remaining payload target is greater than the tip-off threshold and initiates a slow dump sequence if the difference is below the tip-off threshold. The bulk dump sequence includes a single implement actuation to induce material spill until the tip-off threshold is met and the material is staged.

  • Patent number: 9222487
    Abstract: A breather assembly is disclosed for use with a fluid tank. The breather assembly may include a mounting collar having a first end and an opposing second end. The first end of the mounting collar may be connected to a distal end of a fluid tank spout. The breather assembly may also include a breather insert connected to the mounting collar. The breather insert may have a perforated screen extending a distance past a base end of the fluid tank spout. The breather assembly may further include a breather cap having a first end and an opposing second end. The first end of the breather cap may be connected to the breather insert. The breather cap may also have a passage in common with a hollow center of the mounting collar.

  • Patent number: 8997471
    Abstract: A hydraulic system for a machine is disclosed. The hydraulic system may include a fluid tank, a first manifold, a valve body, a second manifold, and a plurality of conduits. The first manifold may be operatively attached to the fluid tank and have at least two inlets and at least one outlet in fluid communication with the fluid tank. The number of the at least one outlet may be less than the number of the at least two inlets. The second manifold may be operatively attached to the valve body and have at least one inlet in fluid communication with the valve body and at least two outlets. The number of the at least one inlet may be less than the number of the at least two outlets. The plurality of conduits may fluidly connect the at least two inlets of the first manifold and the at least two outlets of the second manifold.
