SPACESAVER ROTARY STORAGE SYSTEMS SPECIFICATIONS
6. A zinc-plated lock bar will activate through the external lock on the unit. The unit will have three (3) locking positions. Position one is the unlocked position, where the latch engages upon the operator's release of the foot pedal during rotation. Position two is the locked position, either open or closed as the operator determines. Position three is "free spin" whereby the operator can lock the pedal down and disengage the latch mechanism for ADA compliance.
7. In the locked position an additional security device will prevent the interior from being forced open.
8. All the above components will be field serviceable and replaceable. All fasteners will be removable. Under no circumstances must it be necessary to replace the rotary base for simple field repairs.
9. The self-centering mechanism, consisting of the bell crank; the latch mechanism; and the lock bar activated security device, will be attached to the rotary base using both fasteners and oil- impregnated bronze bushings. No lubrication will be necessary in either the factory assembly or installation procedures. Neither will it necessary to lubricate these components in the field.
10. The rotor base will be assembled after painting at the factory. Pre-paint assembly of any of these components is not acceptable.
11. Leveling of the rotor base will be accomplished through four independently adjustable leveling domes. In seismic zones the levelers will be Grade 5. Calculations indicating compliance with the most current building codes must be submitted where applicable.
12.Access to the bell crank, pawls, and lock bar will also be available through an access panel located in the top of the rotor base. Punched holes are not insufficient.
13.Upon request, testing data demonstrating the life cycle of the pedal-related mechanisms must be available. That data must be based on a minimum of 500,000 pedal activations. Further, the data must demonstrate that after the testing, the mechanism still responds to the operator's actions.
14.A press-formed raceway, circular in design, will capture the ball bearings and prevent burnishment of the rotor base.
15. Letter-size units will have a minimum of twenty- two (22) five-eighths diameter hardened carbon steel ball bearings. Legal-size will have a minimum of forty-four (44) ball bearings.
16. The back of the rotor base will be punched to accept rotation space closure strips.
C. Assembled Rotor Bottom Specifications
1. The rotor bottom consists of four major components: The deep drawn rotor bottom, an
integrated and slotted rotor base shelf pan, a circular ball bearing cage, and the carriage bolt/oil impregnated bronze bushing/lock nut fastener.
2. The deep draw rotor bottom will be fabricated from 12-gauge cold rolled steel.
3. The deep draw rotor bottom will have a circular press formed raceway which matches perfectly the identical raceway formed in the rotary base. The combination of these two identical raceways will create a circular channel within which all ball bearings will rotate. This design eliminates burnishment of the steel components. In effect, the surfaces will last a lifetime. No other detail is acceptable.
4. The rotor base shelf pan will be slotted to accept standard dividers and the DAC divider (patent pending.)
5. The ball cage will secure each individual ball bearing within a circular notched design. The ball cage will be fabricated from 16 gauge steel.
6. The assembled rotor bottom will attach to the Base with a minimum one-half inch carriage bolt. An oil impregnated bronze bushing will provide continuous lubrication. A lock nut will secure the connection. No other styled connection will be accepted.
D. Doors, Center Panel, Rotor Top, and Canopy Top
1. Doors will consist of an inner door panel and an outer door panel, which are welded to form one structure. Doors attach to the rotor bottom without the need for fasteners of any type.
2. Shelves and RO Accessories will attach to the inner door panel at not more than one and three quarter inch adjustability.
3. All shelves and RO accessories will be supported at a minimum of four points.
4. Attachment of RO accessories will be in combination of both door louvers and four metal screws. The door louvers are to be punched for this specific purpose.
5. Shelves may be attached with screws, but it is not required, except above security drawers.
6. Center panels will be full-length and triple-flanged to meet and connect to the doors and the rotor bottom. An option for pass through shelves must also be available when specified.
7. The center panel will attach to the door every five and one-half inches. The attachment will be by a unique clip and screw fastener. The same style fastener will attach the center panel to the rotor bottom as well.
8. The rotor top will compression fit into the door. No fasteners of any type are required.
9. The rotor top will have slotted strips integrated into the design so that both standard and DAC dividers can be used in the top openings of any unit.
10.An oil impregnated bronze bushing will be integrated into the rotor top design to allow the canopy top to secure the rotating center of gravity.
11. The canopy top will be sized to reflect the overall depth and width of each unit.
12. The canopy top will be reinforced for strength and to eliminate shipping damage.
E. End Panels, Posts, and Vinyl Door Strips
1. Each Starter unit will be complete with two end panels, four posts, and four vinyl door strips.
2. Each Adder unit will be complete with two posts and four vinyl door strips.
3. Each Full Adder will be complete with four posts, four vinyl door strips and two post fillers.
4. The design of the post will include a reverse bevel for clearance during rotation.
5. The vinyl door strips will be available in a variety of colors to match the most popular standard colors.
6. The vinyl door strip will snap-fit into the post for a smooth and flush appearance. Self-adhesive door strips are not acceptable.
7. End panels and posts will connect to each other without the need of fasteners of any type. The end panel/post assembly will connect to both the base and the canopy tops with minimum of five- sixteenths inch bolts.
8. Locks will be installed on the post immediately above the primary foot pedal.
9. An identification ring will be placed around the lock to identify the servicing Area Contractor for Spacesaver Corporation.
G. Accessories: Internal and External
1. A full range of accessories will be available to effectively store all types of files, folders, multi- media components, books, binders, hanging folders, etc.
2. Bidder agrees that any specified standard accessory will remain available to owner for the entire five-year warranty period.
3. External accessories will include: extended canopy tops, rotation space closure strips, laminated door face options, fabric wrapped tack boards which cover the end panels, range finders and card holders.
4. All new accessories will be designed to be installed within the specified Rotary Storage Units.
H. These specifications are subject to changes that improve the performance of Spacesaver Rotary Storage Systems.
