The system shall be installed according to Air Force Figure TSH804-02 and shall consist of the following components:

a. Carriages, including drive trains

b. Stationary platforms

c. Wide Span Shelving (Appendix B)

d. Bin Shelving (Appendix C)

e. Controls

f. Rails

g. Elevated flooring

h. Ramps

i. Safety devices

j. Mechanical fasteners, anchors, and all other items required to install the mobile storage system.

3.2. PERFORMANCE AND PHYSICAL CHARACTERISTICS

Shaw AFB, SC - App D - Page 2

3.2.1. SYSTEM OPERATION

Each carriage shall have a crank mechanism on both ends, which shall be turned manually clockwise or counterclockwise to move the carriage in the desired direction. No more than five pounds of force on the crank shall be required to move a fully loaded carriage.

3.2.2. CARRIAGES

Six moving carriages shall be provided; upon which bin shelving shall be installed on three and wide-span shelving shall be installed on three as shall on AF Drawing TSH804-02. These carriages shall move as required after the appropriate crank is turned. All carriages shall be capable of supporting a minimum load of 1,000 pounds per carriage foot. No system component shall deflect greater than 0.5 percent of the distance between supports when fully loaded. No component shall exhibit permanent deformation after the maximum load has been removed.

3.2.2.1. FRAME

The frame shall consist of aluminum or steel channel, welded or bolted together to support a fully loaded shelving section.

Cross bracing shall ensure rigidity. Bumpers shall be mounted on the frame, spaced appropriately to minimize carriage contact.

The frame shall be designed for an integral drive train.

3.2.2.2. DRIVE CHAIN

Drive chain shall connect a set of gear reduction sprockets from the crank shaft to the drive shaft.

3.2.2.3. DRIVE SHAFTS

Drive shafts shall be made of steel. Splices or connections to other sections of the drive shaft, drive wheels, and gears shall be slotted for key joints or use shoulder bolts.

3.2.2.4. BEARINGS

Bearings shall have a static load rating equal to or greater than the maximum bearing loading, including applicable safety factors, under all operating conditions. Bearings shall be permanently lubricated, securely mounted, and properly housed for protection from physical damage.

3.2.2.5. WHEELS

Shaw AFB, SC - App D - Page 3

Each carriage shall have two wheels per rail. Each carriage shall have at least two drive wheels and at least two guide wheels (drive wheels may also act as guide wheels). All wheels shall be balanced, hardened steel. Wheels which are connected to the drive shaft shall be slotted for key joints. Wheels shall be capable of supporting the fully loaded carriage.

Wheels shall not slide or lose contact with the rail.

3.2.2.6. GUIDANCE SYSTEM

All carriages shall use flanged wheels or guide bearings for guidance over the rails. If flanged wheels are used, each carriage shall have a minimum of two flanged guide wheels. If guide bearings are used, then each carriage shall have a minimum of four sets of guide bearings. Guide bearings shall be precision machined and permanently lubricated.

3.2.3. STATIONARY PLATFORMS

One stationary platform shall be provided upon which wide-span shelving shall is installed as shown on AF Drawing TSH804-02.

It shall be of the same construction and height as the carriages, but shall be anchored to the rails or floor and require no drive train.

3.2.4. WIDE-SPAN AND BIN SHELVING

Wide-Span and Bin Shelving, which conforms to the requirements of Appendices B and C respectively, shall be bolted to the carriages and stationary platforms. These bolts shall be made secure to prevent disassembly.

3.2.5. FACE PANELS

Fire retardant, decorative, face panels shall be fastened to both ends of all carriage units and stationary platforms. Face panels shall provide a rigid mounting location for controls and card holders. The face panels shall cover the entire width and height of the shelving sections.

3.2.6. ROW IDENTIFICATION

Two card holders shall be installed on each face panel for row identification. The card holders shall be at least five inches wide by three inches high and mounted at eye level so that operators can locate numbers easily. Row identification cards will be made up by the warehouse personnel according to their

Shaw AFB, SC - App D - Page 4 established location assignment practices. A blank card will be provided by the Contractor for each card holder.

3.2.7. RAIL INSTALLATION

The carriages shall move over steel rail assemblies. After leveling the rails, load bearing grout shall be used to fill in any gaps between the rail assemblies and the existing floor.

3.2.8. ELEVATED FLOORING

Elevated flooring shall be constructed of fire retardant plywood, which is able to support a load of 75 pounds per square foot. A covering (such as “Endura” or equivalent) shall be installed on top of the plywood panels. Flooring shall be sized to fit between the rails, level with the top of the rails, in order to provide a safe walking surface for personnel. The elevated flooring shall be enclosed on all sides by ramps or panels to prevent dust from gathering on the rails and drive chain.

3.2.9. RAMPS

Metal ramps shall be installed to prevent tripping when entering the system.

3.2.10. SAFETY DEVICES

3.2.10.1. ANTI-MOVEMENT LOCK

Each carriage shall be equipped with a mechanism which locks the carriage in place while the operator is in the aisle.

3.2.10.2. SYSTEM LOCK

When closed, the entire system shall be capable of being locked shut either via a key or padlock connected to the mobile aisle system or floor.

4. QUALITY ASSURANCE PROVISIONS

4.1. INSPECTIONS

The system shall be inspected to verify that it meets all the requirements of sections 1, 2, and 3 of this appendix and the cover purchase description. These inspections shall be

Shaw AFB, SC - App D - Page 5 completed as part of the systems checkout test and again as a part of the quality conformance test.

4.2. TESTS

The following tests shall be performed on the system as part of the system checkout test and again as a part of the quality conformance test.

No. Paragraph Description

1. 3.2.1. A functional test of 24 hours in three eight hour increments shall be made on the system.

It shall be tested randomly over this period.

Test each crank by turning it both clockwise and counterclockwise. If the carriage does not move in the desired direction, the system fails the test.

2. 3.2.2. The deflection test shall be performed randomly on any system component. The Contractor shall load the selected shelves to maximum loading.

The shelves shall remain loaded for four continuous hours. At the end of the four hour period, the system shall be checked for deflection. If any system component deflects more than 0.5 percent of the distance between supports when fully loaded, the system fails the test. If any component exhibits permanent deformation after the maximum load has been removed, the system fails the test.

3. 3.2.10.1. Test each anti-movement lock. If a carriage can be moved with a lock activated, the system fails the test.

4.3. CERTIFICATIONS

The Contractor shall provide certification that the following requirements have been met. All certifications shall be provided in accordance with the Contract Data Requirements List.

No. Paragraph Certifications

1. 3.2.2. All carriages are capable of supporting a minimum load of 1,000 pounds per carriage foot.

Shaw AFB, SC - App D - Page 6

2. 3.2.2.3. Drive shafts are made of steel. Splices or connections to other sections of the drive shaft, drive wheels, and gears are slotted for key joints or use shoulder bolts.

3. 3.2.2.4. Bearings have a static load rating equal to or greater than the maximum bearing loading, including applicable safety factors, under all operating conditions. Bearings are permanently lubricated, securely mounted, and properly housed for protection from physical damage.

4. 3.2.2.5. All wheels are balanced, hardened steel.

Wheels which are connected to the drive shaft are slotted for key joints. Wheels are capable of supporting the fully loaded carriage.

Wheels are precision ground so they do not slide or lose contact with the rail.

5. 3.2.2.6. If guide bearings are used, they are precision machined, permanently lubricated and adjustable to ensure proper alignment between the wheel and the rail.
