1. SCOPE

1.1. GENERAL SCOPE

This appendix establishes the minimum performance, design, fabrication, installation, and test requirements for cantilever rack, Building 510 at Truax Field WI. The work shall be completed in accordance with this appendix, the cover PD, AF

Drawing NWS912-01. This appendix is intended to cover 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 and the following

ANSI American National Standards Institute

MH16.3 Specification for the Design, Testing and

Utilization of Industrial Steel Cantilevered

Storage Racks

3. REQUIREMENTS

3.1. SYSTEM DESCRIPTION

The cantilever rack 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 a variety of Government forklifts. The racks shall be located and configured as shown on AF Drawing NWS912-

01. The cantilever rack shall conform to the requirements of the

CSN: NWS912 Attachment 08 3

TRUAX FIELD – APP G - Page 2

Rack Manufacturers Institute (RMI) Specification for the Design, Testing and Utilization of Industrial Steel Cantilevered Storage

Racks. The cantilever rack shall consist of the following components:

a. Bases

b. Uprights

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 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 48” arms.

Each base shall be anchored to the floor to prevent the rack from tipping when loading the upper arm levels. If leveling shims are necessary, they shall have a hole corresponding 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 180 inches and a capacity of 10,000 pounds. Uprights shall be spaced on 48-inch centers. 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.

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.

3.2.4.1. HORIZONTAL BRACING

A minimum of two 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 braces are 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

Five (5) arms shall be provided for each upright. These arms shall be spaced as shown in AF Drawing NWS912-01. 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 a minimum upward pitch of

1/4 inch per foot to compensate for any deflection under full rated load. No arm, when loaded to capacity, shall deflect below the horizontal plane.

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

4. QUALITY ASSURANCE PROVISIONS

TRUAX FIELD – APP G - Page 4

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 purchase description. These inspections shall be completed as part of the quality conformance test.

No. Paragraph Description

1. 3.2.1. Maximum loads shall be placed randomly in the 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 permanent deformation, the system fails the test.
