and to remain securely attached to the forklift during all aircraft loading

operations. The devices shall have a safety factor of at least 2 when the rated load

is equally applied to both devices.

b. A pintle type, towing hitch shall be located at the center, end of the aircraft

loading attachment opposite the fork insertion pockets.

c. The aircraft loading attachment shall be of adequate length, width, height, and

strength to support aircraft loading operations as specified (see 3.3.9.15.1)

d. Unless otherwise specified (see 6.2), the final paint (see 3.3.1.3) and markings

(see 3.3.2) shall be consistent with the colors of the forklift on which the aircraft

loading attachment is attached. The top of the aircraft loading attachment shall

have "XX,XXX LBS" (where XX,XXX equals the final push/pull capacity of the

vehicle) stenciled in 1-1/2 inch high letters with paint.

e. Storage devices to allow the aircraft loading fork attachment to be stored on the

forklift without modification to the forklift.

3.3.9.16 Wheel guards. The forklift shall be designed so that material is not thrown off the

rotating tires onto cab windows or light assemblies. If wheel guards are used, each wheel guard

shall be capable of supporting at least 300 pounds in any one square foot area without evidence

of damage.

3.3.9.17 Boom assembly. The boom shall be designed to provide fore and aft (horizontal)

extension and retraction, and tilting movement for raising and lowering the fork carriage. The

maximum angle that the boom can be tilted, with rated load on the forks, shall be limited to 45

degrees. The forklift shall be capable of meeting all requirements of this document with this

limitation.

3.3.9.18 Boom attachments. The boom shall be designed to accept multiple attachments as

needed. Each attachment shall have its own set of instructions and load chart. Attachments may

have up to one standardized hydraulic fitting to allow for hydraulically powered operations by

the attachment. When specified (see 6.2), the forklift shall be provided with any combination of

an engine installation/removal attachment or a pintle hook attachment. If a pintle hook

attachment is required, then aircraft loading forklift attachment (see 3.3.9.15) is not required.

Attachments shall be easily installed or removed, requiring at most 2 people, and not more than

15 minutes per attachment.

3.3.9.18.1 Engine installation/removal attachment. When specified (see 6.2), the forklift will be

shipped with an engine installation/removal attachment. The engine installation/removal

attachment shall have sufficient capacity to remove a C-130 engine and propeller combination

weighing up to 5,500 lb. at 16 ft. load center (when measured from the forward most part of the

forklift), without the use of outriggers. The attachment shall provide at least 24" of horizontal

travel while the vehicle remains stationary. The horizontal travel shall be hydraulically operated

by the vehicle operator from the cab. The horizontal travel can also be accomplished with a
