Consolidated Evidence Long Term Storage

Mobile Shelving Storage System for Long-Term Storage of Evidence. High-Density, Mechanical Assist, Mobile Storage system with four post adjustable shelving on wheeled carriages that travel on rails, eliminating the need for multiple fixed aisles.  The proposed system will consist of nine (9) moveable carriages and four fixed, non-moveable shelving units.  The carriages should be approximately 48 inches deep (allowing 24 inches of shelving space on each side of the carriage), 35 feet long and approximately 9 feet tall.  The ceiling height of the room is approximately 12 feet tall and a 9-foot shelving height allows for an 18-inch Fire Code stand-off and approximately 18 inches on the top shelf for small and flat packages. 

There are two fixed units, non-moveable (one at each end of the carriages), that are 24 inches deep, 25 feet long and approximately 9 feet tall, same as the other shelving.  An additional fixed shelving unit, 24 inches deep, 25 feet long and approximately 9 feet tall, same as the other shelving, that will be fixed along the front wall.  Lastly, an additional fixed shelving unit, non-moveable, 24 inches deep, 16 feet long and approximately 9 feet tall, that will be fixed along the side wall just inside the main door. 

Within each carriage unit and fixed shelving, the shelving should be divided into 36 or 48-inch-long sections, out to the maximum lengths of each carriage and fixed shelving units, but 48 inches would be the preferred shelving size, with adjustable industrial strength metal shelving and a minimum load carrying capacity of 1000lbs per linear foot.  Mechanical assist control provides mechanical advantage for easy carriage operation with an ergonomically designed three-handled drive operating wheel that transfers power to the carriage’s drive axle.  The current dimensions allow for one aisle, approx. 40-48 inches, when the carriages are opened and closed, in compliance with current ADA standards.   

Movement Controls: Triple arm operating wheels with rotating hand knobs shall be provided on the accessible (drive) ends of carriage units, centered or near centered on the end panel, to permit units to be moved to create a single aisle opening.  Turning the handle transmits power through a drive chain to drive wheels on the carriage.  The drive unit should be synchronized so that power is transmitted to both sides of the carriage, not just one, providing positive tracking – even with unbalanced loads.  There should be a locking mechanism to prevent the inadvertent and unassisted movement of the carriage unit.  The units should also incorporate anti-tip measures, providing an extra measure of system stability and safety, due to the weight and oversized packaging that may be stored. Shelving and cabinets should be fabricated using heavy-gauge steel and extensively reinforced for increased rigidity and strength
