  • Publication number: 20200270107
    Abstract: A portable aircraft maintenance stand includes a frame assembly and a deck. The frame assembly has a base portion and an upper portion. The deck is mounted to the upper portion of the frame assembly and includes a cantilevered portion. The deck also has a gap configured to receive an engine of an aircraft such that the deck at least partially wraps around the engine. The cantilevered portion of the deck is configured to be positioned vertically above a wing of the aircraft while the base portion of the frame assembly is positioned vertically below the wing.

  • Patent number: 9441382
    Abstract: An apparatus and method are disclosed for servicing a vehicle, such as an airplane. The apparatus includes a mobile maintenance platform configured to position in proximity to the airplane and airplane components such as the engine and the fuselage. A cantilever deck provides a slip resistant surface to work on. A gap on the edge of the deck enables the deck to position near the airplane component. Clamps on either side of the gap apply sufficient force to stabilize the component and also serve to close the gap completely, forming a flat surface across. A railing acts as a barrier on the edge of the deck. A frame supports the deck. Adjustable legs support the frame. A jack raises and lowers the legs to regulate elevation of the deck. A tow hitch enables the apparatus to be moved. An adjustable ladder provides access to the deck.

  • Publication number: 20150354277
    Abstract: An apparatus and method are disclosed for enabling work on at least one aircraft or vehicle component, such as a tire. A work surface provides a platform for operators to service tires, including aircraft tires. The work surface includes depressions and guardrails to guide and secure the tires in a desired location along the work surface. A load portion, such as a ramp, facilitates loading/unloading of the tires onto the work surface. At least one column portion supports the work surface, and raises and lowers. A motor powers a screw jack which actuates the column portion. A cable support carries wires and cables to and from the apparatus. A buffer strip goes around the bottom of the beam, and acts to detect proximity to the mount surface. A tool tray and keyhole slots hold tools around the work surface. Power outlets on the work surface provide power.
