SPECIFICATIONS

1.0 TITLE OF REQUIREMENT

Manual Diverter Roller (MDR) Tables

2.0 REQUIRING ORGANIZATION

TSA – Office of Security Capabilities (OSC)

3.0 INTRODUCTION

Provide a MDR with a Transition Table and Plexiglas barrier that mate up to the existing AT X-Ray unit’s cut-out and runs parallel to the existing re-composure rollers on the X-Ray Operator’s side. This ancillary equipment would be designed to allow the X-Ray Operator to immediately pull suspected accessible property through the existing X-Ray unit’s cut-out, onto the Transition Table, and push the accessible property down the gravity-fed MDR. The MDR will allow the accessible property to remain in the proper queuing order (First-In First-Out), while the Plexiglas provides a barrier between the traveling public and their carry-on bags which have been designated for additional screening.

4.0 BACKGROUND

With an overall objective of increasing throughput of the AT X-Ray units, reducing the secondary search cycle time, and maximizing staff utilization, the MDR will allow the TSA to realize the full potential of the AT X-Ray units and make the system operationally viable. During current checkpoint operations, there is a significant delay in X-Ray processing while the dynamic TSO responds to a call for a “bag check” as well as the requirement to re-run accessible property after the secondary search is completed. Immediately diverting suspected accessible property will mitigate the impact on X-Ray utilization by reducing the time the X-Ray process is blocked when the X-Ray Operator calls for a threat area search. When an alarmed item may not be resolved using the new OSARP procedures, the X-Ray operator will pull the accessible property through the existing X-Ray unit’s cut-out and onto the MDR. The suspected accessible property will then be sent to the end of the MDR for a target search. The MDR shall hold up to three bags at a weight of 75 lbs. per bag. A dynamic TSO will retrieve the suspected accessible property from the MDR in the order received to ensure proper queuing of images at the AVS.

The MDR shall provide independently adjustable T-legs which allow the top of the MDR to have height adjustability between at least 61.0 cm (24 in) and 83.8 cm (33 in) in 2.5 cm (1 in) increments.

The MDR shall include a removable, yet securable, reinforced end-stop barrier to prevent accessible property from falling off the MDR with a Minimum height of 6.3 cm (2.5 in) and a Maximum of 8.9 cm (3.5 in). The end-stop shall stand up to continual pounding of bags weighing 75 lbs. See Section 5.2.1 for additional information.

The MDR T-legs shall have ball-and-socket type hard rubber self-leveling feet. Minimum base diameter shall be 1.5”. Feet shall be adjustable up to 3”.

The MDR framing, legs and rollers shall be colored gray, black, natural aluminum or stainless steel.

The MDR shall allow for the MDR to be attached by removable bolts to the Transition Table defined in Section 5.2.

The MDR shall have pre-drilled holes, or similar capability, on both sides to accommodate a left or right hand installation, (See Figures 1 and 2) in the field, of the Plexiglas divider defined in Section 5.1.2.

5.1.1 Rollers

The rollers for the MDR are expected to meet the following requirements:

The MDR rollers shall be a durable plastic with a minimum load capacity of 75 lbs. per roller.

The MDR rollers shall be 50.8 cm (20 in) in length with a ±3.18 mm (1/8 in) tolerance.

The MDR Rollers shall have a minimum diameter of 1 ¼” to a maximum of 1 7/8” and spacing between rollers should be a minimum of 1/8” to a maximum of 1/4”.

The MDR shall comply with ASME B20.1, Safety Standards for Conveyors and Related Equipment Section

6.11. (See Attached)

5.1.2 Plexiglas Divider

The purpose of the Plexiglas is to provide a barrier between the traveling public and their carry-on bags which have been designated for additional screening.

The MDR shall have a 70% “smoke gray” tinted Plexiglas divider installed on the outside of the roller assembly mounted flush to the roller assembly in order to provide a barrier between the suspected property on the MDR and the cleared property on the re-composure rollers of the X-ray system.

The Plexiglas divider shall meet the following physical requirements:

Have a height of 61.0 cm (24 in), relative to the top surface of the Transition Table. The Plexiglas divider shall be adjustable to maintain a level plane along the length of the divider in relation to the plane of the Transition Table surface (See Figure 1);

Have a total length of 157.5 cm (62 in); Plexiglas shall extend past the end of the MDR by 33 cm (13 in).

Be 6.35 mm (1/4 in) thick with a ±0.4 mm (1/64 in) tolerance.

The edges of the Plexiglas divider shall be 3.18 mm (1/8 in) routered edges.

The Plexiglas shall be made available to order as a replacement part. If ordered as a replacement part, the Plexiglas shall include mounting hardware.

Dimensions of the Plexiglas shall be in accordance with the following drawing. Unless otherwise noted, all measurements allow for a ± 6.35 mm (1/4”) tolerance. Please note, the drawing below is in inches.

5.1.3 Safety

All components of the Manual Diverter Assembly will be free of sharp corners or edges that can puncture, cut, or tear the skin or clothing, or otherwise cause bodily injury or damage to accessible property. The MDR will be designed in such a manner so that it does not present a safety hazard.

5.2 Transition Table

The MDR will be attached to a Transition Table that is expected to meet the following requirements.

The Transition Table shall be height adjustable to allow for the top of the Transition Table to be between 73.7 cm (29 in) and 88.9 cm (35 in) in 2.5 cm (1 inch) increments.

Dimensions of the Transition Table shall be in accordance with the following drawing. Unless otherwise noted, all measurements allow for a ± 6.35 mm (1/4”) tolerance.

The top of the Transition Table shall be 11 gauge (3.18 mm) (1/8 inch) TYPE 304 Stainless Steel.

The Transition Table shall have pre-drilled bolt-holes as specified in the drawing to allow the MDR to be bolted flush to the Transition Table. This assembly shall allow the MDR be capable of adjusting and maintaining up to a 12:1 pitch while the Transition Table is level to grade.

A left and right hand Transition Table shall be designed to accommodate the AT-2 X-ray specific orientation in the field. Each AT is designated as a Right Hand or a Left hand unit; this refers to the orientation of the X- Ray Operator when standing on the public side of the Checkpoint. Depending on where the X-Ray Operator is seated, the cut-out to retrieve bags from the X-Ray tunnel is different. (See Figures 1 and 2)

The Transition Table shall have one table leg that mounts to the four holes depicted on Figure 4 and Figure 5.

This positioning of this leg shall provide support to handle 75lbs and enable the x-ray operator to operate the AT without interference of the leg.

The Transition Table leg(s) shall have ball-and-socket type hard rubber self-leveling feet. Minimum base diameter shall be 1.5”. Feet shall be adjustable up to 3”.

The Transition Table shall be made available to order as a replacement part. If ordered as a replacement part, the Transition Table shall include mounting hardware. Please note, the drawing below is in inches.
