20K DAMAS Salient Characteristics

Brand Name. Manufactured in Germantown, Wisconsin, USA. It shall have the following salient characteristics:

1) The 20K DAMAS system shall be capable of loading self-propelled vehicles, towed trailers, and other items winched into the aircraft, with a minimum tire diameter of 24”. (Items with smaller tire diameters such as helicopters and caster wheels will require a HelMAS, pooched plate, system.)

2) The system shall be compatible with C-130, C17 & C5 aircraft.

3) When under the maximum rated axle load of 20,000 lbs, pressures on aircraft cargo floor or cargo ramp will never exceed 50 psi.

4) The 20,000 lb maximum axle rating shall be based on a 2-to-1 Safety Factor (S.F.). This means that a

40,000 lb axle can be placed on the Shoring before any permanent deformation of aluminum will occur. The point of “permanent deformation” is considered the point of failure. Many manufacturers have very low safety factors, if they have any at all. (A stronger system takes more aluminum, and costs more. This is where some companies are able to get a a contract awarded by bidding on an inferior/weaker shoring kit.

This has led to some incidents of failure, equipment damage, aircraft damage, and injury)

4) Each left/right runway assembly shall be rated for a maximum single axle weight of 20,000 lbs. Runway components (Ramp Sections, Wedges, and Lead Ups) will be 30" wide, no thicker than 4”. Each Ramp

Sections will have two carry handles on each side, for a total of four carry handles.

5) The DAMAS assembly will have a top surface composed of high-traction rungs/cleats that run laterally across each runway.

6) The DAMAS system will be modular, with the capability to be assembled in numerous lengths (130” to

788”) and heights (0” to 55”), depending on the components chosen for a specific kit.

7) All components that come in contact with the aircraft cargo floor or cargo door have smooth belting bonded securely to the base (e.g. Lead Ups, Wedges, Ramp Pads, and Stands).

8) All components must be certified by ATTLA # 2012.02.06.01 Rev 1.

9) All components must NOT subject to DoD Manual 4140.65-M, and are to be compliant with the

International Standards for Phytosanitary Measures (ISPM), United States Department of Agriculture (USDA), Animal Plant Health Inspection Service (APHIS) Plant Protection and Quarantine (PPQ) program, and the

International Plant Protection Convention (IPPC) .

10) To eliminate F.O.D. all Lynch Pins will be tethered, either to a Ramp Pad or a Hitch Pin.

12) Each DAMAS, and sub-component, will be fabricated by a welder certified by the American Welding

Society (AWS).
