Figure 1

Gravity Roller Conveyor Cross Section

3.2.7.1. ROLLERS

Rollers shall be approved by the Contracting Officer’s Technical Representative (COTR). Each roller shall have a minimum load capacity of 550 pounds. The conveying surface of the rollers shall extend a minimum of 1/4 inch above the frame. The rollers shall be located on maximum 6-inch centers. The rollers shall be easily removable for inspection and maintenance. Rollers shall be designed to have a minimum service life of ten years at a usage rate of 5,000 hours per year based on CEMA 401, using an equivalent radial load which is greater than or equal to 10,500 pounds divided by half of the minimum number of rollers under a 463L pallet (28 rollers) and a roller surface speed of 40 feet per minute.

3.2.7.1.1. ROLLER TUBES

The roller tubes shall be minimum 2-1/2-inch diameter steel tubing with 11-gauge wall thickness. All roller tubes shall have electro-deposited zinc coatings. Roller tube plating shall comply with ASTM B633, Service Condition 2, Type I.

3.2.7.1.2. ROLLER AXLES

Axles shall be a minimum 11/16-inch hex cold-rolled steel. All axles shall be of the through type and shall be pin/ring retained to facilitate easy removal of rollers for cleaning and maintenance.

3.2.7.1.3. ROLLER BEARINGS

Roller bearings shall be the non-precision, dust-tight, light-oil lubricated, zinc-plated, anti-friction ball type. Greased bearings shall not be acceptable. Each bearing shall have a minimum static load rating of 275 pounds. The bearings shall be securely mounted by swaging the roller ends or an equally suitable method approved by the COTR. The bearings shall be shielded or steel labyrinth sealed on both sides. If shielding is used, the shield shall be a solid, rigid material that will

FA8604-20-R-8116 Attachment 1 REV1 Page 12 of 45 not flake or otherwise introduce foreign material into the bearing. Felt shields shall not be acceptable. The roller bearings shall have separate steel inner and outer rings.

3.2.7.2. ROLLER FRAMES

Roller frames shall be standard 10-foot sections where possible.

All roller frames mounted to the floor shall be minimum 5-inch structural steel channel at 6.7 pounds-per-foot. Frame sections shall be bolted together flush end-to-end with lock washers or self-locking nuts to provide a continuous, level-conveying surface. Axle holes shall be punched in the high position on the channel so the conveying surface is a minimum 1/4-inch above the top of the frame. Axles shall easily slide into and out of the axle hole without binding or interference from the frame.

3.2.7.3. CROSSTIES

A minimum of four steel crossties shall be positioned in every 10-foot section to provide structural support. Crossties shall be welded to the inside of the roller frames. Crossties shall not interfere with operation of rollers. Crossties shall be equally spaced along the 10-foot length of the frames.

Crossties shall not be used to anchor roller sections.

Figure 2 Typical Gravity Roller Conveyor Section

3.2.7.4. REMOVABLE PALLET STOPS

Removable pallet stops shall be located as shown on AF Drawing BLR908-01. The removable pallet stops shall withstand repeated impacts of pallets weighing up to 10,000 pounds moving at 40 feet per minute. The removable pallet stops, pallet stop

FA8604-20-R-8116 Attachment 1 REV1 Page 13 of 45 supports, pallet guides, conveyor frames, and pallets shall not exhibit damage, deformation, or decreased performance from such impacts. Removable stops shall extend a minimum of 4 inches above the conveying surface. The removable pallet stops shall be painted Red. The removable pallet stops shall not have sharp edges or corners that create a safety hazard. The removable pallet stop plates shall be constructed as shown on Figure 3.

When removable stops are removed, there shall be no remaining protrusions that can snag the pallets or interfere with pallet transfer. A hand opening approximately 1 inch high by 5 inches wide shall be punched in removable stops to provide a handle.

The top of the hand opening shall be located approximately 1 inch below the top of the stop. The removable stops shall slide between two support angles.
