1. GENERAL DESCRIPTION OF CAROUSEL STORAGE SYSTEMS

1.1. This specification covers the minimum Government requirements for two (2) “Turn-Key” Carousel Storage

Systems. The system shall store 2,372 LFI of Top Tab Letter file folders. Carriers shall be delivered to an operator comfortably, at an optimum ergonomic height. The Carousel Storage System shall be designed in accordance with requirements identified in these specifications, and shall meet all safety requirements as outlined in enclosure 1. The contractor shall provide the following (with all dimensions being +/- 3 inches):

2. TWO (2) CAROUSEL STORAGE SYSTEMS INCLUDING THE FOLLOWING MINIMUM

TECHNICAL FEATURES:

2.1. All sides of the Carousel shall be enclosed including bottom, and powder coated in light grey (or any standard color). The dimensions are 139.4”H x 115.35”W x 45.47”D with a 12” worktable across the front of the carousel. There are to be 21 carriers with full length telescopic ball bearing guided roll out drawers with secure latches. Each carrier will have 2 roll out drawers in a 3x4 configuration (7 total filing rows). The drawers are 12.8”W x 16.14”D x 10.04” clear height.

2.2. The operator access height is 29.5”.

2.3. The carriers shall be attached to the conveyor chains and guide track with 4 carrier arms per side and attached with four bolts per carrier side thereby increasing stability. This design also eliminates the carousel downtime experienced by carousels with only two arms per side that cannot rotate if one arm breaks. With four carrier arms per side if one arm breaks, the second arm keeps the carrier rotating until a technician can replace it.

2.4. Each carousel must have dual motors. Dual Motor Drive Technology eliminates the torque problems created by single motor drive systems providing longer service for the entire system. And in case of failure of one of the motors the second motor provides redundant power eliminating the need to hand-crank the unit.

2.5. Dual Safety Redundancy, two overrides provide complete operator safety for unit function without the need to hand crank. Emergency Safety System Bypass ensures the carousel is fully operational, even if any part of the safety system is not. The emergency safety bypass system is an immediate solution to light curtain alignment problems or other safety system failures. When in safety bypass, the unit will operate by simply closing the access door. Carousels that allow the door to stay open while overriding safeties ae not acceptable. Microprocessor Control Override ensures that retrieval and stocking can still take place, even if the control malfunctions. Should a microprocessor failure occur, the manual override provides an immediate drive alternative

2.6. Each carousel must be a six-sided cabinet (full top and bottom, standard) designed for cleanliness, security and maximum protection for articles being stored. The skins must have interlocking lips (male/female) for maximum structural integrity and load carrying. This feature also ensures that the carousel can only be installed plumb thereby reducing the wear and tear that internal moving parts can experience if not plumb to each other.

2.7. Each carousel shall have continuous guide tracks welded in place at the factory to assure proper cycling of the carriers yielding maximum uptime and eliminating the need for costly track adjustments.

2.8. Drive chains shall be installed and pre-tensioned at the factory. No field adjustment shall be required following installation ever.

2.9. The carousels must use sealed self-lubricating bearings ensuring longer life and less maintenance.

2.10. The carousels shall have split, locking doors with upper and lower full-length piano hinge style safety touch thresholds to ensure article security and operator safety. The threshold shall break away from the rotating carriers creating a safety gap (no pinch point in case of safety failure) for protecting personnel and stored items from any risk by bringing the carousel to an immediate stop. The carousel must come with three sets of keys. All keyed to the same number.

2.11. The carousel must have a 25% Imbalance Drive Capacity to allow for maximum imbalance while still rotating.

2.12. Self-monitoring LVS light curtain shall be installed at the operator access opening. This shall provide safety features that protect the operator from injury when the carriers are moving. This feature shall immediately stop the carriers from moving, when an operator’s hand/arm is in danger of injury.

2.13. Lockable sliding door(s), with two keys shall be provided (so files can be secured).

2.14. An emergency stop button shall be provided at the operator’s station that is of the mushroom type and colored red.

2.15. An operator lighting system shall be provided (i.e. full width LED energy saving, overhead lighting)

2.16. Quality and durable construction of all system components. System structural components shall be rigid and stable.

3. ELECTRICAL REQUIREMENTS

3.1. The Carousel shall operate on 208 VAC, 3 phase power. The contractor shall run conduit, fasteners and wiring from a government supplied breaker to the Carousels. They shall also provide a lockable disconnect switch on each machine between the breaker and the carousel.

4. WARRANTY

4.1. Supplies and services furnished shall be covered by warranty from defects in design, materials and workmanship. The warranty shall be the manufacturer’s standard commercial warranty, which shall conform to all the requirements of the contract. Acceptance of the manufacturer’s standard commercial warranty shall not minimize the rights of the Government under clauses in the contract, and in any conflict that arises between the terms and conditions of the contract and manufacturer’s warranty, the terms and conditions of the contract shall take precedence. The warranty period shall commence from the date of acceptance. All warranty work shall be provided by a factory authorized distributer.
