STATEMENT OF OBJECTIVES

HIGH DENSITY MOBILE SHEVLING OR EQUAL

I. INTRODUCTION: The 554th Red Horse Squadron (RHS) seeks a High Density Mobile Shelving solution that will maximize space utilization for the 554 RHS Material Control, which has limited available space.

II. SCOPE: The 554 RHS requires mobile shelving units with customized, modular and component-based storage solutions in order to provide more efficient storage for the mission. The system will maximize utilization of finite space, enhances overall utility, and conforms to physical security and safety standards. The solution shall enhance parts availability, increase asset accountability, maximize space utilization, aid/assist in issue/recovery, and solve problems associated with current deficiencies in properly storing parts, tools and equipment required for the 554 RHS’s mission.

III. SYSTEM REQUIREMENTS

A. The system consists of storage units mounted on track-guided carriages to form a compact storage system. System design permits access to any single aisle by manually moving units until the desired aisle is opened. The carriage/rail system provides uniform carriage movement along the total length of travel, even with unbalanced loads.

B. Carriage System Design and Features: The carriage system consists of a formed structural steel frame with machined and balanced wheels riding on steel rails surface mounted to the floor. Rails shall be types selected by the manufacturer to ensure smooth operation and self-centering of mobile storage units during travel without end play or binding. Rail types, quantities and spacing shall be selected by the manufacturer to suit installation conditions and requirements. All bearings used in the drive mechanism shall be permanently shielded and lubricated.

C. Movement Controls: Triple or single arm operating wheels with rotating hand knobs shall be provided on the accessible (drive) ends of shelf units, centered on the end panel, located 40 inches (1051MM) from the base of each unit to permit units to be moved to create a single aisle opening. Turning the handle transmits power through chain drive to drive wheels on each carriage.

D. Drive System: The system shall be designed with a positive type mechanically-assisted drive which minimizes end play, ensures there is no play in the drive handle, and that carriages will stop without drifting.

1. System shall include a chain sprocket drive system for each movable carriage to ensure that carriages move uniformly along the total length of travel, even with unbalanced loads. All system components shall be selected to ensure a smooth, even movement along the entire carriage length. Drive system gearing shall be designed to permit 1 lb. of force applied to the drive handle to move a minimum of 4,000 lbs. of load.

2. A tensioning device shall be provided on each chain drive with provision for adjusting tension without removing end panels.

3. All bearings used in the drive mechanism shall be permanently shielded and lubricated.

E. Safety Features:

1. Color-coded visual indicators shall provide verification that carriages are in a locked or unlocked mode.

2. A single safety lock button, mounted on each operating wheel hub, will permit moving a carriage in either direction to create a new access aisle when pulled out (unlocked), or locking the carriage when pushed in.

F. Finishes:

1. Fabricated Metal Components And Assemblies: Manufacturer’s standard powder coat paint finish.

2. End Panels, Accessible Ends: Plastic laminate, manufacturer’s standard textures and patterns. Manufacturer’s standard powder coat paint finish.

The information provided in Attachment l is for guidance purposes to help depict the direction of the requiring activities vision. Alternate proposed storage solutions will be accepted and evaluated if within the scope of this contract.

IV. MANUFACTURED COMPONENTS

A. Rails:

1. Material: ASTM/AISI Type 1035 or 1045 steel, manufacturer’s selection.

2. Capacity: 1,000 pounds per lineal foot (1385kg/M) of carriage.

3. Minimum Contact Surface: 5/8 inch (16MM) wide.

4. Provide rail sections in minimum 6 foot (1.83M) lengths.

5. Rail configuration shall permit attachment to top of structural floor system with provision for leveling rails to compensate for variations in floor surface level.

6. Provide rail connections designed to provide horizontal and vertical continuity between rail sections, to gradually transfer the concentrated wheel point load to and from adjoining rail sections. Butt joints are not permitted.

7. [Anti-Tip Rail Form Covers: Manufacturer shall provide for protection if required to prevent damage to rails during concrete back pours. when anti-tip devices are installed.

B. Floor / Ramp:

1. Floor/Ramp Sheathing: Minimum 3/4 inch (19MM), 5-ply underlayment grade plywood. Particle board sheathing materials are not permitted.

2. Provide fire retardant treated floor/ramp materials when required by code.

C. Carriages:

1. Provide manufacturer's design movable carriages fabricated of welded or bolted steel construction. Galvanized structural components and/or riveted carriages are unacceptable.

2. Provide fixed carriages of same construction and height as the movable carriages, anchored to rails. Setting fixed shelving directly on floors is not permitted.

3. When required, provide bolted carriage splices designed to maintain proper unit alignment and weight load distribution.

4. Design carriages to allow the shelving uprights to recess and interlock into the carriages a minimum of 3/4 inch (19MM). Top mount carriages are unacceptable.

5. Provide each carriage with two wheels per rail.

D. Drive / Guide System:

1. Design: Provide drive system which prevents carriage whipping, binding and excessive wheel/rail wear under normal operation.

a. If line shafts are used, all wheels on one side of carriage shall drive.

b. If synchronized drives are used, a minimum of one wheel assembly driving both sides of carriage at center location required. Drive shaft shall exhibit no play or looseness over the entire length of that assembly.

2. Shafts: Solid steel rod or tube.

3. Shaft Connections: Secured couplings.

4. Bearing Surfaces: Provide rotating load bearing members with ball or roller bearings. Provide shafts with pillow block or flanged self-aligning type bearings.

E. E. Wheels:

1. Capacity: Minimum load capacity per wheel: 3200 lbs (1455kg).

2. Size: Minimum 5 inches (127MM), outside diameter drive wheels.

3. Guides: Determined by manufacturer; minimum 2 locations.

F. F. Face Panels:

1. Materials: Plastic laminate clad particle board with plastic edging on vertical edges.
