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.

MIl-STD-209K APPENDIX B

materiel lift point LF for helicopter EAT is 3.2.  Since this value is greater than the 2.3 materiel lift point LF required for crane lifting, 3.2 will be used.

= R  x lF = 3,293 x 3.2 = 10, 538 lb

= R  x lF = 3,103 x 3.2 = 9,930 lb

= R  x lF = 2,541 x 3.2 = 8,131 lb

= R  x lF = 2,612 x 3.2 = 8,358 lb

B.5.1.8 Determine the required ultimate load, U.

= T  x 1.5 = 10,538 x 1.5 = 15,807 lb

= T  x 1.5 = 9,930 x 1.5 = 14,895 lb

= T  x 1.5 = 8,131 x 1.5 = 12,197 lb

= T  x 1.5 = 8,358 x 1.5 = 12,537 lb

B.5.1.9 Testing Requirements. Table B-1 Lift Test Requirements.

B.5.1.10 Determine the apex height, H .

The height of the apex equals the height of the lowest provisions, plus the vertical differ- ence between the horizontal plane and the plane of the provisions, plus the vertical dis- tance between the CG and the apex, K.
