NOTES:

(1) Other grades of proof tested steel chain include Proof Coil (Grade 28), Hi-Test (grade 43 Chain, and Transport (grade 70) Chain. These grades are not recommended for overhead lifting and therefore are not covered by this standard.

(2) Rating of multi-leg slings adjusted for angle of loading between the inclined leg and the horizontal plane of the load.

HT = Hand Tucked Splice.

For Hidden Tuck Splice (IWRC), use vales in HT (FC) columns.

MS = Mechanical Splice.

S = Poured Socket or Swaged Socket.

NOTE: (1) These values are based on slings being vertical. If they are not vertical, the rated load shall be reduced. If two or more slings are used, the minimum horizontal angle between the slings shall also be considered.

HT = Hand tucked Splice

For Hidden Tuck Splice (IWRC), use values in HT columns of Table 3.

MS = Mechanical Splice. S = Poured Socket or Swaged Socket.

NOTES:

(1) These values are based on slings being vertical. If they are not vertical, the rated load shall be reduced. If they are not vertical, the rated load shall be reduced. If two or more slings are used, the minimum horizontal angle between the slings shall also be considered.

(2) These values only apply when the D/d ratio is 15 or greater.

(3) These values only apply when the D/d ratio is 25 or greater.

D = Diameter or curvature around which the body of the sling is bent. d = Diameter of rope.
