MIL-STD-209 Lifting And Tiedown ProvisionsThis standard establishes dimensional limits, design considerations, positioning requirements, and strength requirements for lifting to include helicopter sling load HSL and tiedown provisions for lifting or tying down tanks and other tracked vehicles, tactical wheeled vehicles, helicopters, and other military equipment shipped assembled or disassembled in unboxed or uncrated condition, and for restraining cargo or accessories to such equipment. The lifting and tiedown requirements in this standard are necessary to permit compatibility between military equipment and the transportation systems used for deployments.

Table II - Load Requirements for Cargo Tiedown Provisions.

	LB	LB	LB	LB
Load-carrying range of equipment	0 - 3,000	> 3,000 to <10,000	> 10,000 to < 52,900	> 52,900
Load-carrying capacity (design load) of each tiedown provision	2,500	5,000	10,000	15,000
Note: The load-carrying capacity of the cargo tiedown provisions do not have to match the load-carrying range of the equipment since there will be several provisions to restrain the load.

d. Loads applied in the vertical, longitudinal, and lateral directions shall be applied statically and independently for not less than 6.0 seconds and shall be not less than the required design limit load in each direction.

e. Failure is defined as any visible or measurable permanent deformation, yielding, or bending to the provision or other structural component. A possible failure indication during the initial material analysis shall be justification to use more detailed analysis and testing methods (for example, calibrated measurements, finite element analysis, magnetic particle inspection, X-ray, fatigue testing, ultimate testing, and so forth). Cracks in welds will constitute test failure.

f. The contractor shall provide a material analysis showing the ultimate load is not less than 1.5 times the required design limit load for the provisions.

g. In addition to the other requirements of this paragraph, another load using banding shall be applied to the provisions for not less than 6.0 seconds. Selection of provisions for testing will be based on differences in provision design. The banding load shall be the design limit load of the cargo tiedown provision. The banding load shall be applied with 2" x .065" banding in a complete loop. A complete loop is that in which the the banding is looped through the cargo tiedown provision on the vehicle, through the cargo being restrained, and then looped back such that the the ends of the banding are joined together. Tearing of the banding, as a result of the banding load being applied, will constitute failure.

5.4.6 Directional capabilities.

Cargo tiedown provisions will be designed to optimize the interface between the cargo area and the cargo tiedown apparatus. Floor or wall mounted cargo tiedown provisions shall permit the cargo tiedown provision to rotate a minimum of 180° about its base and be functional at least 75° to either side of the true vertical in any rotational position (Figure 11). Side and end mounted cargo tiedown provisions shall translate a
