1. SCOPE

1.1. GENERAL SCOPE

This appendix establishes the minimum performance, design, fabrication, installation, and test requirements for cantilever rack for the 628th Logistics Readiness Squadron (LRS) in the

Flight Line Support Facility (FLSF) at Joint Base Charleston, South Carolina. The work shall be completed in accordance with this appendix, the Cover PD, and Air Force (AF) Drawings BCH205-

01. This appendix covers all equipment, materials, and labor necessary to complete installation of the system.

1.2. DEFINITIONS

Arm - Horizontal load carrying member which locks to the upright.

Base - Horizontal load carrying member which rests on the floor and supports the upright.

Bracing - Steel bracing which is used to attach adjacent uprights to each other and space adjacent uprights from each other. Bracing prevents twisting and swaying.

Upright - Vertical load carrying member which supports the cantilever arms. Also known as column.

2. APPLICABLE DOCUMENTS

Applicable documents shall be per section 2 of the Cover PD.

3. REQUIREMENTS

3.1. SYSTEM DESCRIPTION

The cantilever racks covered by this appendix are intended for storing a variety of nonstandard sized items. Storage and retrieval operations within the cantilever rack will be performed with the use of a Government-furnished general purpose forklift or the rider-reach truck specified in Appendix G. The racks shall be installed as shown on AF Drawing BCH205-01. The cantilever rack shall consist of the following:

A. Bases

B. Uprights

Joint Base Charleston – App C – Page 2

C. Bracing (horizontal and diagonal)

D. Arms

E. Mechanical fasteners and all other items required to install the cantilever rack.

3.2. CHARACTERISTICS

3.2.1. CANTILEVER RACK DESIGN

All components shall be constructed to produce a rigid, stable rack. The design and construction of each load bearing component shall ensure that the component is capable of sustaining the maximum load with a safety factor of not less than 1.65 to 1. No component of the cantilever rack shall exhibit any plastic (permanent) deformation.

3.2.2. BASES

There shall be one base for each upright in the system which shall be used as a shelf. It shall provide support for the upright and shall prevent the racks from leaning or collapsing when the rack is loaded to capacity. The base shall be at least as long as the upright depth plus the length of the arms. At a minimum each base shall be anchored to the floor on each end to prevent the rack from being pushed over backwards when loading the upper arm levels. If leveling shims are necessary, they shall have a hole that corresponds to the hole in the base and shall be equal in width to the base.

3.2.3. UPRIGHTS

Uprights shall have an overall height of 14 feet and a minimum capacity of 8,000 pounds. They shall have a means for adjusting arms on nominal three-inch centers from 24 inches above the floor to six inches from the top of the upright. Uprights shall be spaced on 48-inch centers.

3.2.4. BRACING

Horizontal and diagonal bracing shall be used to maintain alignment of the cantilever racks under varying loads and horizontal stresses. The bracing shall hold the uprights vertical, maintaining the proper spacing between the uprights.

Joint Base Charleston – App C – Page 3

3.2.4.1. HORIZONTAL BRACING

A minimum of three horizontal braces are required between every two uprights. These braces shall be evenly spaced along the upright.

3.2.4.2. DIAGONAL BRACING

A minimum of one diagonal, X-type brace is required between every other set of uprights (i.e., between uprights 1 and 2, 3 and 4, 5 and 6, etc.). They shall also be installed at each end of every row.

3.2.5. ARMS

Arms shall be provided and installed at levels as shown on AF

Drawing BCH205-01. Each arm shall be capable of supporting

2,000 pounds. The arms shall be 48 inches long and shall fasten securely to the uprights by use of a connector. The arms shall have an upward pitch between 1/4 inch per foot and 3/4 inch per foot to compensate for any deflection under full rated load. No arm, when loaded to capacity, shall deflect below the horizontal plane. Arms shall have removable end stops to prevent loose materials from falling off the arms. Arm capacity labels shall be applied to all arms. The labels shall be approximately 2” x

4” with the font size easy enough to read from a few feet away.

3.2.5.1. CONNECTORS

The connector shall be capable of transferring all loads and external forces of the arm to the column without failure of the connection, or damage to the column or connector. The connectors shall ensure a snug, metal-to-metal fit between the horizontal and vertical load carrying members.

3.2.5.2. SAFETY CATCH FEATURE

If adjustable connectors are used, a safety catch feature shall be provided on each arm to securely lock the arm to the column.

Design of the catch feature shall preclude the arm from dislodging due to impact or movement of the racks.

3.2.6. ROW MARKERS

Card holders shall be installed on the end of each rack section for row identification. One card holder shall be mounted on each end of every row. The card holders shall be large enough

Joint Base Charleston – App C – Page 4 for a minimum 8 inch by 8-inch card to be displayed. The card holders shall be mounted between 7 feet and 10 feet from the floor. 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. Card holders and cards shall be constructed of plastic.

4. QUALITY ASSURANCE PROVISIONS

4.1. INSPECTIONS

The cantilever rack shall be inspected to verify that it meets all the requirements of sections 1, 2, and 3 of this appendix and the Cover PD. These inspections shall be completed as part of the system 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. Maximum loads shall be placed randomly in the cantilever rack system. After not less than four hours, the test loads shall be removed, and the rack examined for signs of deformation. If any component of the system exhibits plastic deformation, the system fails the test.

2. 3.2.5. Maximum loads shall be placed randomly in the cantilever rack system. After not less than four hours, the system will be examined for signs of deformation. If any arm deflects below the horizontal plane, 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.

Joint Base Charleston – App C – Page 5

No. Paragraph Certifications

1. 3.2.1. The design and construction of each load bearing component ensures that the component is capable of sustaining the maximum load with a safety factor of not less than 1.65 to 1.
