Under 1918AppII Table 1, use 5 drop-forged clips for a 1-inch rope and space them 6 inches apart. See the Tables for Selected Miscellaneous Auxiliary Gear in 1918 App II for the mandatory table that provides minimum clip counts and spacing when manufacturer recommendations are not available.
Under 1918AppII Table 1, for a 7/8-inch rope made of other (non-drop-forged) clip material, use 5 clips and space them 5 1/4 inches (13.3 cm) apart. Refer to the Tables for Selected Miscellaneous Auxiliary Gear in 1918 App II when no manufacturer's certificate or recommendation exists.
Under 1918AppII Table 2, natural fiber rope and rope slings are rated using a safety factor of 5. That means the working load values in the table are the allowed loads after dividing the rope's nominal breaking strength by 5; use the table values for safe lifting when manufacturer data are not available. See the Tables for Selected Miscellaneous Auxiliary Gear in 1918 App II for the published capacities.
Under 1918AppII Table 2, a 1-inch natural fiber eye-and-eye sling has these capacities (pounds): vertical hitch 1,800 lb; choker hitch 900 lb; basket hitch capacities by angle to horizontal are 3,600 lb (0°), 3,100 lb (30°), 2,600 lb (45°), and 1,800 lb (60°). These values assume the table's Safety Factor = 5 and should be used when manufacturer data are not available; see 1918 App II for the official table.
Under 1918AppII, endless (grommet) natural fiber slings have higher listed capacities than comparable eye-and-eye slings because the construction distributes load differently; for example, a 1-inch endless natural fiber sling is listed at 3,200 lb vertical, 1,600 lb choker, and basket hitch capacities of 6,500 lb (0°), 5,600 lb (30°), 4,600 lb (45°), and 3,200 lb (60°). Use the 1918 App II endless-sling section when no manufacturer certificate is available.
Under 1918AppII Tables 3A and 3B, polypropylene rope and rope slings are rated using a safety factor of 6. That means the working load numbers in the table are derived by dividing nominal breaking strength by 6; use these table capacities for safe lifting when manufacturer data are not available. See the Polypropylene Rope and Rope Slings tables in 1918 App II for specific sizes and hitch configurations.
Under 1918AppII Table 3A, a 1-inch polypropylene eye-and-eye sling is listed with a vertical hitch capacity of 2,200 pounds. These values use a safety factor of 6 and are provided in the appendix when manufacturer recommendations are unavailable; consult 1918 App II for the full table.
Under 1918AppII, if slings are not vertical the rated load listed in the tables must be reduced for the angle, and if two or more slings are used you must also consider the minimum horizontal angle between the slings when determining capacity. The appendix explicitly notes that non-vertical conditions and multiple-leg arrangements reduce rated load and require angle consideration; see 1918 App II for the guidance.
Under 1918AppII Table 4A, a 1/2-inch Grade 80 alloy steel single-leg chain sling (90° to horizontal) is listed with a rated load of 12,000 pounds (approximately 5,400 kg). These rated loads are in the appendix for use when manufacturer certificates or recommendations are not available; see 1918 App II for the table.
Under 1918AppII Table 4A notes, Proof Coil (Grade 28), Hi-Test (Grade 43), and Transport (Grade 70) chains are not covered by this standard and are not recommended for overhead lifting. The appendix covers Grade 80 alloy steel chain slings for overhead lifting; see 1918 App II for details and the note.
Under 1918AppII Table 4B, the maximum allowable wear of cross-sectional diameter at any point for a 3/4-inch chain or coupling link is 0.105 inches. Use these allowable-wear numbers in the appendix when inspecting chain and when manufacturer guidance is not available; see 1918 App II for the table.
Under 1918AppII Table 5, a 1-inch shackle with a 1 1/8-inch pin is listed with a safe working load of 5.6 tons (2,000-lb tons), which equals 11,200 pounds. The table gives safe working loads in 2,000-lb tons for common shackle sizes; consult 1918 App II for the full shackle table.
Under 1918AppII wire rope tables, HT means Hand Tucked Splice, MS means Mechanical Splice, and S means Poured Socket or Swaged Socket. When an Independent Wire Rope Core (IWRC) is used and a Hidden Tuck Splice is present, the tables instruct you to use the HT-column values for IWRC cases; see the wire rope tables in 1918 App II for the specific columns and notes.
Under 1918AppII, the basket-hitch rated-load values apply only when the D/d ratio (D = diameter or curvature around which the sling is bent; d = rope diameter) meets the table’s required minimum: some basket values apply only when D/d ≥ 15 and others only when D/d ≥ 25, as noted in the table. Check the specific wire rope table notes in 1918 App II to determine which D/d requirement applies to the listed basket capacities.
Under 1918AppII, employers must use these mandatory appendix tables when manufacturer certificates or the manufacturer’s use recommendations are not available. The appendix is explicitly designated as mandatory for use in the appropriate sections of part 1918 in the absence of manufacturer data; see the opening note in 1918 App II.
Under 1918AppII, if a specific size or detail is not listed (for example, chain sizes not in Table 4B), the appendix advises consulting the chain or sling manufacturer for guidance. The note in Table 4B specifically directs users to consult the manufacturer for other sizes; see 1918 App II for that note.
Under 1918AppII, if the tables list vertical values only, you must reduce the rated load when the sling is used at an angle and account for the angle between multiple slings; the appendix repeatedly notes that rated loads are based on vertical slings and must be reduced for non-vertical use. If the table does not provide the exact reduced value, use manufacturer guidance or an appropriate engineering calculation while following the principles in 1918 App II.
