Topics covered
- Transportability requirements
- Transportability problem items
- Materiel acquisition process
- Transportability assessments
- Transportability approvals
- Payload and shipping data plates
- Slinging and tiedown criteria
- Airdrop criteria
Questions and answers
What makes materiel a transportability problem item?
TPIs are materiel in its shipping configuration which, because of its size, weight, fragile, or hazardous characteristics or lack of adequate means for lifting and tiedown, will be denied movement, will require special permits or waivers and special equipment or handling, or will be unacceptably delayed when moving within existing or newly designed transportation systems. (paragraph 1-1)
What must transportable materiel meet for public highways?
Meet State and Federal legal and operational standards for the design and use of public highways. (paragraph 2-1)
When must materiel carry its rated payload during transport?
Except for equipment that does not carry its payload during transport (such as wreckers, dump trucks, and material handling equipment), the item will be designed (or procured) to carry their rated payload during all of its required transport modes (worldwide road, rail, air, sealift). (paragraph 2-1)
What information must a transportability or shipping data plate show?
Have a transportability and/or shipping data plate that will show tiedown and lifting points, locations, and strengths, and the location of the center of gravity (see MIL STD 209). (paragraph 2-1)
What transportability criteria must materiel comply with?
Comply with transportability criteria prescribed in MIL STD 1791 and MILSTD1366. (paragraph 2-1)
