1.0 GENERAL

1.1 Scope

The vendor will furnish factory trained labor, materials, equipment, special tools, and service required to provide a complete and ready-to-use electrical high density movable aisle system as specified and shown on drawings. Substitutions or deviations from the specifications and drawings must be submitted with each bid in writing with detailed production drawings indicating each substitution and deviation.

1.2 Manufacturer's Qualifications

A. To insure the highest standard of uniformity and quality control, acceptable manufacturers of the high-density movable storage system shall be those that are fabricated in the USA from all American made parts. The track, carriage, end panels and shelving components are to be manufactured at one location from sheet, bar and tubular steel stock. Assembly type manufacturers an&'or manufacturers who do not manufacture all major components will not be considered£L

B. The model offered will have been manufactured for a penod of five years with engineering updates and have a national reputation as a producer of the system specified.

C. Local vendor to provide factory trained personnel and inventory all parts locally. Vendor shall provide four-hour response time during normal working hours. Vendor must be authorized dealer for manufacturer with in-house service personnel on staff. This system cannot be provided b~ sub-dealers, brokers, or unauthorized agents.

1.3 Related Work by Others

This system shall be installed on a floor that is properly prepared by others and finished in accordance with these specifications.

1.4 Submittals

All bidders are required to submit with their bid, manufacturer's general catalog, actual color swatches and hardware and component specifications which include detailed drawings indicating all dimensional, material, and design information pertaining to the quoted system.

For uniformity and appearance, all carriages, steel end panels, and shelving shall be identical color, where specified, as selected from the manufacturer's actual color charts.

Powder coat. An epoxy polyester hybrid powder is electronically applied using a series of automatic and manual powder application guns to a 2.0 mils minimum thickness. The powder system is environmentally safe with no volatile emissions or hazardous waste generated during the coating process. After curing, the finish is inert which results in no off-gassing.

1.6 Warranty

The manufacturer shall guarantee all parts ~with the exception of lamps for a period of 10 years.

1.7 Contract Award

The owner reserves the right to reject any and all bids and award this contract on the basis of highest value, quality and compliance with this specification. An owner's rep will verify~ specifications at the time of delivery. Any deviation from bid specs may result in rejection of product.

2.0 PRODUCTION SPECIFICATION

2.1 Rails shall be minimum 1045 steel bar stock of minimum I 1/2" wide x 3/4" high. Leveling pads and floor anchors shall be on minimum 9" centers on both sides of rail along the entire length of each rail with steel shims to level at each floor anchor. Each pad shall be anchored with two lag bolts set into floor anchors. There shall be a minimum of two guide rails per system. Rails to be leveled by surveyors transit or laser.

2.2 Plywood (particle board not acceptable) will be utilized between rails to 1/8" below rail surface for tile or 1/4" for carpet. Final floor to be flush - no gaps at side of rail, which could pose a tripping hazard.

2.3 Provide Steel Ramp Plate at front of system. Ramp shall not extend beyond front of end panel.

2.4 Wheels shall be precision steel and rest on sealed self-lubricating pillow blocks on both sides of the wheel assuring smooth operation. At least two wheel frames on each base shall have center guide to fit precisely into guide rail. All wheels must be a minimum of 5" in diameter. Wheels shall be precision ground and have a Brinnel hardness of 207/285. Wheel frames shall be welded from 10-gauge steel.

2.5 Drive shafts shall be solid steel. A drive wheel shall be located at every rail. Systems without a drive wheel at every rail will not be considered.

2.6 Carriage section "C" shape 11 ga. minimum 1000 lbs per foot rating. 

2.7 Shelving uprights must be precision recessed 5" into carriages and side bolted with 1/4" nut, bolt and lock washer to eliminate "sheer". Surface mounting of uprights is not acceptable nor is the use of sheet metal (Tec) screws.

2.8 All levels of all double face ranges will be composed of two shelves allowing Independent adjustability on both faces of all levels without tools. Straight through shelves not acceptable. Shelves on all ranges will have 18 Ga. steel side fillers (supports) that will prevent media from becoming trapped or hidden behind the front upright.

2.9 All ranges must provide canopy tops that are bolted to uprights to achieve a one-piece monolithic structure to avoid racking and tipping.

2.10 Total system will operate from a single 120-volt power source. Power to be transferred by overhead cables in scissor arms from source to moving units. Units that are individually connected by flex cables to individual outlets are not acceptable.

2.11 All electronics are to be located in a locked compartment in the front panel. Electronic located on top of shelving or in carriage base are not acceptable.

2.12 System to have three (3) safety systems:

A. Primary. The open reset switch is located on the front panel of every movable range. When the aisle is completely opened, the ranges on both sides of the aisles are automatically "locked" by the reset switch. The aisle will not close, even if another control switch is depressed. The user is never in danger.

B. Secondary. Lower safety bar (sweep) to be located on carriage 1/4" above floor. Any momentary contact with this bar will stop movement of range in less than" I " of travel.

C. Tertiary. All movable ranges must have a "stop" switch. Activating any stop switch will terminate all shelving movement immediately.

2.13 All movable units will have the ability to be moved manually in the event of a power failure.

2.14 Momentary contact with "open" switch will cause any or all ranges to move sequentially to create an aisle. Once the aisle has opened completely, the primary safety is automatically engaged; preventing any further movement while aisle is occupied.

2.15 All overhead wiring will be enclosed in conduit and will be placed within metal raceways in front panels. Metal scissor arms will transfer power between ranges.

2.16 All electrical controls, wiring, and switches shall be a minimum of2 inches above existing floor.

2.17 The complete system shall be U.L. Listed

2.18 Components Gauges:

Carriage Frame 11 Gauge

Wheel Frame 10 Gauge

Upright Frame 16 Gauge

Canopy Top 19 Gauge

Front Panel 19 Gauge

Shelf 18 Gauge

Shelf Bracket 18 Gauge

2.19 Seismic Overhead Anti-Tip: (Optional)

Metal brackets with two hardened rollers will be bolted to top crosspiece of the welded upright. Overhead devices that attach to the canopy or top shelf are not acceptable.
