Manufacturer’s instructions and recommendations for delivery, storage and handling requirements shall be followed by the contractor.

5B. COMPONENTS

I. RAILS

The Contractor shall provide rails of types selected by the manufacturer to ensure smooth operation and self-centering of mobile storage units during travel without end play or binding. Except where otherwise specified in this document, rail types, quantities and spacing shall be selected by the manufacturer to suit installation conditions and requirements. Rails shall conform to ASTM/AISI Type 1035 or 1045 steel of the manufacturer’s selection; sections shall be provided with minimum lengths of 6 feet.

The Contractor shall lay out rails using full length units to the maximum extent possible; cut lengths shall be used only at ends to attain total length required. The Contractor shall locate and position the rails properly, following dimensions indicated on approved shop drawings. The Contractor shall verify thickness of finished floor materials to be installed and install the rails level 1/16 inch above finished floor surfaces.

The Contractor shall position and support rails so that no movement occurs during grouting, and shall set rails in a full grout bed, completely filling any voids across the entire length of all rails including rail connectors. Contractor shall verify floor level, allowing for a minimum 1/4 inch of grout under high points. Sides shall be trimmed up flush with rails to ensure proper load transfer from rail to supporting floor; using shims in lieu of full grouting is not permitted.

The Contractor shall ensure rails are installed within the following tolerances:

• Variation from true level within any module shall not exceed 3/32 inch.

• Variation from true parallel between adjacent rails shall not exceed 1/16 inch, measured perpendicular to rail direction.

• Variation in height shall not exceed 1/32 inch, measured along any 10 foot rail length.

The Contractor shall verify rail position and level, anchoring rails to structural floor system with anchor type and spacing indicated on approved shop drawings, providing the location and details of all anchorage devices to be embedded in or fastened to other construction.

Rail connections shall 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 in this installation. Rail configuration shall permit attachment to top of structural floor system with provision for leveling rails to compensate for variations in floor surface level. Rails shall have tongue and groove rail joints to maintain wheel contact when carriages move from one rail section to another ensuring smooth load transfer and movement. Rail weight capacity shall be 1,000 lbs. per linear foot of carriage. Minimum rail contact surface shall be 5/8 inch in width.

II. CARRIAGES

The Contractor shall provide manufactured metal carriages measuring as follows:

• Mobile Storage # 1 - Fixed wide span shelving (3 units): (1) 108" x 96" x 30 (2) 108" x 96"" x 30" (3) 108" x 48" x 30"; Mobile carriage (10 carriages total): 40 shelving units - 95" x 42" x 32";

10 shelving units - 95" x 30 x 32"

• Mobile Storage # 2 - Fixed shelving units (2 total): 97" x 42" x 18"; Mobile Carriage (3 carriages total): 6 shelving units - 97" x 42" x 36"

Carriages shall consist of a formed structural steel frame fabricated of welded steel construction; galvanized structural components and/or riveted carriages are unacceptable. Spliced or welded joints shall be fully welded to ensure no permanent set or slippage when exposed to nominal operating forces. All connections shall be concealed so bolts are not visible. Carriage components shall be fabricated to ensure no more than 1/4 inch maximum deviation from a true straight line over a 42 inch shelf. Carriages shall allow the shelving uprights to recess and interlock into the carriages with variation of recess into carriage < 1” allowed with top mount carriages acceptable. Carriage surfaces, assemblies, end panels, and accessible ends of the units shall be surfaced with the manufacturer’s powder coat paint finish; color samples shall be provided to the COR at the time of submission of final system drawings.

A. MOBILE

The Contractor shall provide mobile carriages with machined and balanced wheels riding on steel rails attached to the concrete slab. Multiple carriage units shall be fastened together to form movable bases. Each carriage shall have two wheels per rail. The Contractor shall ensure that all wheels track properly and centering wheels are properly seated on centering rails. Carriages shall use roller guide bearings or double flange wheels to guide precisely and maintain carriage alignment on rails. Wheels shall be precision machined and balanced units with permanently shielded and lubricated bearings. The carriage/rail system shall provide uniform carriage movement along the total length of travel, even with unbalanced loads.

B. FIXED

The Contractor shall provide two (2) fixed shelving units of the same construction as the movable carriages on Mobile Storage #2, anchored to rails; and three (3) fixed shelving units on Mobile Storage #1, anchored setting directly on platform is acceptable. Where required, the Contractor shall provide bolted carriage splices to maintain proper unit alignment and weight load distribution. The Contractor shall position fixed carriage units to align with movable units.

III. SHELVING

Shelving units installation shall follow the layout and details shown on the approved drawings and manufacturer's printed installation instructions.

The Contractor shall position shelving units level and plumb placed at the proper location relative to adjoining units and related work following approved drawings for fabrication and install of system components. Shelving units shall be permanently fastened to fixed and movable carriages with vibration-proof fasteners, reinforced to withstand movement stresses and stabilized following the manufacturer's written instructions.

IV. DRIVE SYSTEM

A line-shaft drive system shall be designed with a positive type mechanically-assisted drive which minimizes end play and shall also ensure that no play over the entire length of that assembly or in the drive handle. The shaft shall be a solid steel rod or tube and the shaft connections shall be secured couplings.

The drive system shall prevent carriage whipping, binding and excessive wheel/rail wear under normal operation, and those carriages stop without drifting. Drives shall move front and rear simultaneously; the drive system for each movable carriage shall ensure that carriages move uniformly and evenly along the total length of the track/rail and across the length of the carriages even with unbalanced loads. All bearings used in the drive mechanism shall be permanently shielded and lubricated.
