2.14. The RT will extend, upon local command.

2.15.

The time to fully extend the RT from the retracted position will be less than one (1) hour (T), and fifteen (15) minutes (O).

2.16.

The time to retract the RT from the fully extended position will be less than one (1) hour (T), and fifteen (15) minutes (O).

2.17. The RT will have a backup manual crank to retract the tower.

2.18. The RT will have a backup manual crank to extend the tower.

2.19.

To retract and stow the RT trailer will take no more than two (2) people of 50 percentile female size. The “stowed” position is defined as the tower being fully retracted and the entire system is configured for transport.

2.20. The RT controls will be on the trailer.

2.21. The RT controls will be inside a lockable compartment.

2.22. The RT trailer will be non-ground penetrating.

2.23. The RT outriggers will be non-ground penetrating.

2.24. The RT trailer will be level when deployed up to a 10 degree slope

2.25. The RT will have a visual indicator that shows if the trailer is level.

3 Trailer(s): Meet (Y/N/NA) Notes

3.1.

The RT trailer(s) will be towable by a pick-up truck using a standard commercially available hitch. All payload equipment will be removed from the RT prior to transport.

3.2.

The stowed RT will be transported per DOT limitations in accordance with applicable State Department of Motor Vehicles, State Size and Weight Limits. Example:
