PART 2 - PRODUCTS
The Mobile Shelving Maryland storage system shall be an integrated assembly of independent, mobile and stationary ranges. Each range shall consist of rigidly attached sections of shelving. All ranges shall have suitable end panels, intermediate panels, back panels, etc., all as specified. The system shall be level and have flush flooring.
A. The entire Mobile Shelving Maryland system including carriages, the shelving, and the rails shall be manufactured by a firm regularly engaged in the manufacturing of both steel shelving and high-density mobile storage systems for the past ten years.
B. The Vendor shall be responsible for taking and verifying all dimensions for design and installation. The Vendor shall also verify the capacity of existing storage needs and calculate the future requirements for growth.
1. Rail shall be designed to be anchored to sound flooring and allow for leveling adjustment for uneven floor.
2. Rail shall be located and positioned in accordance with the Manufacturer’s instructions, leveled and grouted allowing for a minimum of 0.5” of grout under the rail from the high spot in the floor. Completely fill void between the rail and floor with a non-shrink grout. Shimming of rails is not acceptable in whole for support of rail. Each rail shall have a minimum width of 2.375" and all rails must extend completely under all stationary ranges.
3. Rail shall be level and shall not exceed .0625" maximum variation from true level within any module and .0625" maximum variation between adjacent rails perpendicular to rail direction. The guide rail shall be a minimum of 0.8" in height and the running rail shall be a minimum of 0.5” in height, and be constructed of solid steel. Each section of rail shall be a minimum of 118" with shorter length used only to terminate each individual rail assembly. In addition, each end of the rail shall be connected by means of twin stainless steel dowels pinned between the rail splice. The splice shall be designed for the most severe operating conditions. Connection joints shall demonstrate vertical and horizontal continuity and gradually transfer the concentrated wheel load to and from adjoining rail sections.
4. The grout used shall be a ready-mixed high strength, controlled expansive grout with superior dynamic load stability, which when mixed with water shall harden rapidly to produce a permanent foundation for the mobile storage system. Grout shall be non-corrosive, non metallic and non-shrink. The grout after curing shall have a minimum strength of 8000 pounds per square inch. Grout shall reduce rail deflection, maintain alignment, and eliminate separation.
2.3 MATERIALS (continued)
B. FLOOR COVERING
Floor covering shall be provided and installed by others.
C. DECKING AND RAMP
The deck is to be constructed of a minimum of .75" Type 1 grade 1-M-2 particle board. There shall be no open gaps between the flooring and the rail. The ramp shall be constructed and finished with the same material as the deck or manufactured from steel.
D. Mobile Shelving Maryland CARRIAGES

3. Carriage splices shall be bolted types designed to maintain proper unit alignment. Carriages shall be straight and square. There shall be no slippage, drag or windup in any splice or welded joint. Fasteners connecting any carriage splice joint shall be vibration-proof in design.
4. Carriage construction shall be such to allow shelving to be securely anchored to each carriage with vibration proof fasteners. Recessed carriages are unacceptable, so as not to cause binding of shelving.
5. Bumpers shall be mounted to the carriage face to help protect material which may extend beyond the shelf face and provide cushioned stop for all carriages without damage or displacement of either material stored or the carriages themselves.
E. Standard carriage lengths shall be from 3’ to 24’, and manufactured to exact specifications for depth and length.
1. Each carriage shall have two wheels minimum per rail, each wheel being the same size. Dynamic load rating on wheel bearings shall be a minimum of 3300 lb. per wheel.

Two guide wheels are required for each guide rail. A minimum of two guide rails are required per carriage, a minimum of four guide wheels shall be incorporated into each carriage.
3. Cast iron wheels shall be used due to their high damping capacity, inherent graphite lubricity and exceptional compressive strength.
F. Mobile Shelving Maryland GUIDANCE SYSTEM
1. Provide gapless wheel guidance system through the use of barrier free matching convex rail and concave guide wheel assemblies. Due to housekeeping and safety concerns, rails with gaps on the sides or grooves in the center are not acceptable.
2. Drive shaft shall be solid steel and a minimum of 0.75". Drive shaft shall be a non-load-bearing member of the drive train for ease of locomotion and service.
