PART 2 PRODUCTS

2.1 MATERIALS – MODULAR FLOOR AND CARRIAGES

A. Design : The Mobile System shall consist of a rail and deck assembly with two (2) or more parallel rails and a platform surface between them, and wheeled carriages, which ride on the rails. The carriages are made to support shelving and they shall have a capacity of 750 pounds per linear foot, as a minimum. All systems are constructed of modular components such that any system can be expanded in both length and width, moved or reconfigured in shape, without the need to discard or replace any parts of the original system.

B. Materials and workmanship : Components are fabricated of high quality, cold rolled carbon steel, free of scale or rust. Exposed edges and corners are free of sharpness or burrs and all workmanship is of the highest quality as measured by the industry. All components of the system are provided by the factory, complete and ready for installation. No purchase of additional parts or materials, nor cutting or fitting of parts in the field is required.

C. Modular floor : The structural frame of the modular floor shall consist of aluminum sub-rail with a steel rail 1/8” x 7/8”, and reinforcement tubes. The deck shall consist of 5/8” plywood covered with commercial grade carpet. The reinforcement tubes shall be of no less than 16 gauge steel ¾” x 1 ½”. To facilitate moving or rearrangement of the installed mobile system, the rails and decking shall not require fastening in any manner to the building floor nor the use of any material or process damaging to the underlying surface. The system shall be equipped with built-in leveling device as follows: Each rail has pairs of leveling screws (one on each side of the centerline of the rail) spaced along the rail not more than 14" apart. The lower ends of the screws rest on a 14-gauge galvanized steel channel placed on the building floor and running the full length of the rails so as to prevent marring or gouging of the floor. Leveling screws are accessible from the top surface of the deck and may be adjusted at any time during installation or after the system is installed, fully loaded and in use. Deck panels are similarly equipped with levelers midway between the rails. No grout, cement, shims or any other material or process damaging to the floor is used. No removal of equipment or disassembly is required to make leveling adjustments.

D. Mobile carriages : The wheel-housing member shall be constructed of no less than 12-gauge steel, at least 2 ¾” high x 2 ½” wide. The wheel-housing are welded to two (2) 14-gauge steel cross members 3” high x 1 ½” deep at the top and 7/8” at the bottom. Four-post shelving shall be attached to the carriage by vibration proof bolts. Design of the carriage is such that the weight-bearing of the upright rests directly over the wheel channels, thus transmitting the load directly to the rail. Top of the first shelf shall not be raised more than 6” above the existing floor. A built-in anti-tip system shall prevent the shelving from tipping.

E. Fixed carriages ; Fixed carriages shall be similar in design and construction to mobile carriages including wheels except that they have clamps which lock the carriage onto the rails.

F. Mechanical-assist drive : The mechanical-assist drive shall consist of a three-spoke handwheel turning a chain and sprocket assembly connected to a 5/8” steel axle driving all wheels and one side of the carriage. Each moveable carriage shall be equipped with a safety locking pin integrated in the handle.

2.2 MATERIALS – FOUR-POST SHELVING

A. Upright frames : Upright frames are made of a minimum of two (2) cross members welded to the posts. The post is made of 16-gauge 1 ¼” x 1 ½” rectangular shaped cold rolled steel. The post is slotted on each side at every one inch increment. The slots are 3/16” wide x 5/8” long and are designed to accommodate a variety of shelf and roll-out drawer configurations. The back of the post is also slotted at every 1 ½” increments. Back post has also two rows of slots at the back, side by side from top to bottom. They are 3/16” wide x 5/8” long with 3/8” between the two rows. The uprights must allow for component integration on either 1” or 1 ½” increments depending only on the selected shelf component.

B. Cross members : Cross members are 4” high x ½” wide. They are made of 16-gauge steel folded to create a “U” shape channel. At both ends, hook type design allows to snap the cross members in both rows of slots at the same time. <

C. Shelf type :

[C-a) Supported type]

1. Full-depth shelves : Full-depth shelves are made of box rolled formed 22‑gauge steel, with “Four Bend” ¾” edge construction which adds additional strength and capacity as well as it creates a hidden safety edge to protect people and items. The full-depth shelves are supported by two longitudinal shelf supports and the appropriate number reinforcement channels. Shelves are also available in 18-gauge steel as an option.

2. Longitudinal supports : [¾” high supports] or [1 ¼” high supports for heavy duty application] are made of one “U” shaped 12-gauge steel channel. A standard formed steel claw is welded at each end to form a complete support. These supports are inserted into the slots located at the back of the post.

3. Front-to-back reinforcement channels : [¾” high reinforcement channels] or [1 ¼” high reinforcement channels for heavy duty application] are made of 12‑gauge steel formed in a “U” shaped channel and are sitting on the longitudinal shelf supports.

4. Base support : A 12-gauge steel special “U” shaped channel is provided for the bottom shelf. The support is inserted at the bottom of each post and anchored to the floor or to the carriage, in compliance with seismic standards.

OR
