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 PLATFORM

The stationary platforms shall be of the same construction and height as the carriages, equipped with face panels, but they shall be anchored to a carriage or floor and require no drive train.

3.2.4. SHELVING SECTIONS

Pallet rack sections which conform to the requirements of

Appendix A, shall be bolted to the carriages. Bin shelving which conforms to the requirements of Appendix D, shall be bolted to the carriages and stationary platforms.

3.2.5. FACE PANELS

Face panels shall be fastened to both ends of all the shelving sections/carriages. Face panels shall provide a rigid mounting location for controls and card holders. The face panels shall be fabricated from steel or laminate panels with covered edges.

The face panels shall cover the entire width of the shelving sections. The face panels shall be of equal height and of a height to cover the tallest shelving unit so there is a uniform look and height to all face panels down the mobile aisle systems. Color selection shall be made available to Truax Field personnel at the Post Award Technical Information Meeting

(PATIM).

3.2.6. ROW IDENTIFICATION

CSN: NWS912 Attachment 04 5

TRUAX FIELD – APP C - Page 4

Card holders shall be installed on the face panels for row identification. The card holder shall be mounted on the face panel in location coordinated with Base personnel. 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 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 ¾” to 1” high, 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. Rails shall be installed no more than seven feet apart. Floor elevation and variance details are not available, however, in Bldg. 400 some variances are to be expected.

3.2.8. RAIL SKIRTS

Rail skirts shall be installed to cover all unfinished edges of the elevated floor, rail, and ramp.

3.2.9. ELEVATED FLOORING

A composite flooring shall be provided. The flooring shall be minimum 3/4-inch-thick high-density polyethylene (HDPE) laminated panels or minimum Resindek LD with Gray Diamond Seal composite flooring. HDPE laminate shall be minimum .050” thick over ¾” mold, mildew and corrosion resistant plywood panel. The

HDPE laminate shall not delaminate from the ¾” plywood substrate. The flooring sheets shall be tongue and groove on long sides forming an integral surface. 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.
