(7)

Eye splices in all regular lay lines and straps must be tucked at least three times.

(8)

Eye splices in lang lay lines must be tucked at least four times.

(9)

When flemish (rolled) eye splices are used on load bearing lines, the strand ends must be secured by:

(a)

Hand tucking each strand three times; or

(b)

Applying a compression fitting (pressed eye fittings).

(10)

Log splices must be used for permanently joining regular lay running line.

(1)

Crew members are notified of the splices being used.

(2)

Yarder boom sheaves are of the Tommy Moore type.

(3)

Splices are on the yarder side of the carriage.

(4)

Lines are arranged so splices do not go through the carriage.

(5)

Spliced strands are trimmed at 6 inches.

(6)

Splices are inspected at least once daily for signs of excessive wear or failure.

(7)

Defective splices are immediately repaired (spliced) or removed from service.

(8)

Jump splices connecting main and slack pulling lines are between 30 inches and 48 inches long and tucked at least three times.

(9)

Splices attaching drop lines to main lines are tucked at least three times.

(11)

Follow Table 7-1 for the length of line strand to unravel to make a long splice in wire rope. The full length of the splice must be twice the length of the unraveled rope.
Table 7-1 — Length of Wire Rope to Unravel When Long Splicing [Table not included. See ED. NOTE.]

(12)

Wire strand ends must be trimmed to the length shown in Table 7-2.
Table 7-2 — Trimmed Length For Wire Rope Strand Ends [Table not included. See ED. NOTE.]
