This tail dock is vertically adjustable from a low position which services the B737 when on tires, to a high position for servicing the B767 while stabilized on aircraft jacks. It is vertically adjustable from a low position which services the B737 when on tires, to a high position for servicing the B767 while stabilized on aircraft jacks. The tail dock is a split-type crane rail-mounted system separating laterally to allow the aircraft to be positioned first in the hangar. Each half of the tail dock is composed of three main structures. The main framework is mounted on the crane wheels and provides the support and guides for the level 1 and 2 through 5 structures. This design allows minimal space restriction around the lower bulk cargo doors while providing a stable system. The level 1 and 2 through 5 structures have independent motorized vertical travel. The level 1 structure provides access to the aft cabin door and full coverage around the horizontal stabilizer and elevators. Slider deck panels are provided on the inboard edge of the platform to adjust the contour to fit snugly against the aircraft skin. The slider deck panels aft of the tail cone extend to the center line of the aircraft providing continuous access around the rear of the aircraft. The APU compartments of both aircraft may be accessed from the hangar floor by retracting the slider panels below the APU. Separate caster-mounted platforms are provided for access to the leading and trailing edges of the horizontal tail. the platforms are sloped to match the angle of the horizontal tail closely. Wheel brakes are provided to secure the platforms in position. A double gate is provided along the outer board handrail to allow materials to be raised or lowered to or from the level 1 deck using a forklift.
Levels 2, 3, 4, and 5 are combined into a single structure, providing vertical fin and rudder access. Each level has slider deck panels on the inboard edge of the platforms, which adjust to fit snugly against the vertical tail or extend to the center line of the aircraft, providing continuous access around the front or rear. Additional slider panel travel is required to allow for full rudder swing. All slider panels have non-marking, Skydrol-resistant, bright yellow bumpers to protect the aircraft. Telescoping handrails and gates are provided at the ends of the platforms to provide fall protection. All decking and slider panels are Aerodeck, skid-resistant steel. All smooth decking is coated with a high-profile non-skid coating.
