Mich. Admin. Code R. 408.14952 - Splicing

Rule 4952. A spliced fiber rope sling shall not be used unless it has been spliced in accordance with the following minimum requirements and in accordance with any additional recommendations of the manufacturer:

(a) In manila rope, an eye splice shall consist of at least 3 full tucks, and short splices shall consist of at least 6 full tucks, 3 on each side of the splice center line.

(b) In synthetic fiber rope, an eye splice shall consist of at least 4 full tucks, and short splices shall consist of at least 8 full tucks, 4 on each side of the center line.

(c) A strand end tail shall not be trimmed flush with the surface of the rope immediately adjacent to the full tucks. This applies to all types of fiber rope and both eye and short splices. For fiber rope under 1 inch in diameter, the tail shall project at least 6 rope diameters beyond the last full tuck. For fiber rope 1 inch in diameter and larger, the tail shall project at least 6 inches beyond the last full tuck. Where a projecting tail interferes with the use of the sling, the tail shall be tapered and spliced into the body of the rope, using at least 2 additional tucks, which will require a tail length of approximately 6 rope diameters beyond the last full tuck.

(d) A fiber rope sling shall have a minimum clear length of rope between eye splices equal to 10 times the rope diameter.

(e) A knot shall not be used in lieu of a splice.

(f) A clamp not designed specifically for fiber ropes shall not be used for splicing.

(g) For any eye splice, the eye shall be of a size to provide an included angle of not greater than 60 degrees at the splice when the eye is placed over the load or support.
