Abstract: Methods of performing assembly or maintenance on an aircraft, systems for performing desired assembly or maintenance on an aircraft, and mobile work stations useful for such systems and methods, where the mobile work stations include a work platform, including an accessway providing access to the work platform; and a moveable base supporting the work platform with one or more platform jacks that can adjustably raise and lower the work platform.

Abstract: The present disclosure provides an aircraft security door as well as methods, systems and apparatus for handling an aircraft security door. In one implementation, a method for installing an aircraft security door onto an aircraft is disclosed. The method includes transferring the aircraft security door to an aircraft service stair, supporting the aircraft security door by a bridge crane coupled to the aircraft service stair, positioning the aircraft service stair in proximity to a fuselage of the aircraft adjacent to an opening in the fuselage, positioning the aircraft security door relative to the opening using the bridge crane, and securing the aircraft security door to the opening.

Abstract: Methods and systems for supporting and/or positioning mechanical components or tools, the methods and system employing work stands that have a moveable base, a vertical support member disposed on the moveable base, a support platform attached to an upper end of the vertical support member via a support coupling that permits independent rotational movement of the support platform, a plurality of extendable arms that are each pivotally coupled at a lower end to the vertical support member and pivotally coupled at an upper end to the support platform, and each extendable arm can be independently and controllably extended and retracted. The work stands further include a controller for controllably extending and retracting the extendable arms to position the support platform in a desired orientation, and a user input coupled to the controller and configured so that a user employing the controller can position the support platform in the desired orientation.

Abstract: Apparatus for moving different movable loads. The apparatus includes channels that can be engaged by a fork lift, pallet jack, or other powered mover. The apparatus also includes a mounting plate disposed between the channels. The mounting plate includes a receiver channel. The apparatus includes a plurality of load support tools that can selectively engage the receiver channel. The load support tools include different respective end effectors. A load can be engaged with the end effector of a selected load support tool such that the apparatus can move the load.
