The Stanley 220531 towbar is used for towing B747 aircraft.

The towbar is used for towing and steering the aircraft by attaching to the aircraft\'s Nose Landing Gear (NLG) and being pulled by a tow tractor. The towbar primarily consists of a cylindrical steel body. At one end of the tow bar is a lunette eye, which connects to the tow tractor. The lunette eye is equipped with a shock absorbing mechanism to reduce the shock load on the NLG. At the opposite end of the towbar is a mechanical head assembly, which connects to the aircraft NLG. The towbar is mounted on an articulated undercarriage with a hydraulic pump and a retract spring which raises and lowers the towbar.

The AGSE-D037 Modular Dock System provides access to service and maintain the DC10, MD11, and A300-600 Aircraft. Vertical dock adjustment is provided by pin legs spaced at three inch intervals.

The support can accommodate engines1, 2 and 3 by exchanging easy to install components for the applicable engine. The pieces securely pin together quickly and easily. The Cowl Door Support also allows for easier maintenance and repair tasks. The door support is functionally equivalent to McDonnell Douglas part number DZZ7287.

The AGSE-D102 Tail Stand is a fixed height, caster mounted, one piece, multi-level stand that provides access to the tail of MD80/90 series aircraft. The first level is accessed from two stairways (located on either side). Level two is a suspended trolley mounted platform that traverses forward and aft. Access is provided by a single stairway from level 1, and a brake secures the level’s position. Two mechanically driven sliders protrude forward from the deck to provide access to the engine pylon. Level 3 is accessed from two fixed stairways (located on either side). The inboard edge has contour adjustable panels (sliders) that provide docking clearance. The sliders are mechanically driven in the rudder swing area. Two vertically adjustable finger decks (with sliders) provide access above the engines. The decks are adjusted using pendant controls that control the motor driven jackscrews. Level 4 is access from the ground using two stairways (located on either side). Sliders are provided on the inboard deck edge.

The AGSE-D089 Horizontal Stabilizer Access Stand is a two piece, single level structure providing access to the horizontal stabilizers and APU of B757 Aircraft. The inboard edge has contour adjustable panels (sliders) that provide docking clearance and retract for APU removal. A lower level of sliders provides access below the APU and to the trap door on the left side. The stand is vertically adjustable to access a jacked aircraft. An articulating stairway provides access to the ground.

The AGSE-T027 B777 Nose landing Gear Dolly is specifically designed for local site transport of the B777 nose landing gear main shock strut with wheels and down lock removed. The dolly consists of a base assembly and fixture designed for securing the gear. A sling is needed to install the gear onto dolly. The gear secures dolly easily using the upper torsion link for an attach point, the axles, and adjustable straps on both sides of yoke. The dolly is towable, with swivel locks and face brakes on the casters.

The AGSE-D160 C130 dock system is designed to provide personnel access to service the aircraft wings, AFT fuselage, and horizontal and vertical tail components. The dock system consists of interlocking elevated platform sections as well as specialized support equipment designed to compliment the platforms. There are three basic platform components; a fixed tail mezzanine, mobile multi-sectional wing stands and AFT fuselage access ramps that allow access between the tail mezzanine and wing stands. Specialized support equipment includes mobile and fixed tool lifts, a rolling sloping longeron stand and deck-mounted wing cradles.
The fixed single deck tail mezzanine structure provides the basis for situating the aircraft and wing stands within the hangar. An access stair and tool lift is provided at the rear corner of the mezzanine deck. The mezzanine deck is reinforced in key locations to allow tail jack placement and use on the deck. The deck is designed to support the repair of a detached Horizontal Stabilizer.
Aft fuselage access ramps provide access to the fuselage and connection between the mezzanine and wing stand. The ramp deck has a sloped transition to accommodate the elevation change between the mezzanine and inboard fuselage stand raised deck. Slider panels are provided along the inboard edge to conform to the fuselage contour. The ramps are caster mounted for precise positioning and relocation within the facility. A hinged deck section is located at the AFT end to allow the unit to be moved into location without requiring movement of other stand sections.
The wing dock system consists of six caster mounted mobile stands per side. Sliders at the inboard and outboard fuel pod locations allow pod removal and installation with the aircraft docked in stands. Slider panels are incorporated along the inboard edge of the inboard stands to provide a deck surface which conforms to the aircraft contour. An access stair and tool lift is provided along the trailing edge of the left and right wing stand set. Deck slider panels are provided at wing and engine jack shoring positions. Cover plates at each wing jack location conceal gaps between jack legs and sliders. Removable and adjustable handrail sections are provided along the perimeter of the assembled wing stands. All stands lock together at the inner corners using bolt or turnbuckle connections.
The mobile tool lifts are provided for convenience at the tail stand and wing stand locations. The wing stand tool lifts are mobile to allow roll-away in the event the wing stands are to be moved or additional aircraft or equipment clearances are required.
The Sloping Longeron stand allows technician access along the full length of the main cargo bay longerons during repair or replacement. It is specifically designed to collapse for a low profile such that it may be rolled under the tail mezzanine and into the cargo bay area. Once positioned along the edge of the cargo bay, it is hydraulically raised into position.
For each wing stand, a set of specially designed wing cradles is provided. These cradles are designed to quickly set-up and allow the detached outer wing to rest directly on the wing stand deck. The cradles are fitted with screw jacks and are manually height adjustable.
