Volume B30.30 includes provisions that apply to the construction, selection, installation, attachment, testing, inspection, maintenance, repair, use, and replacement of wire rope, hybrid rope, and synthetic fiber rope and rope-lifting components used in conjunction with equipment addressed in the volumes of the ASME 830 Standard. These provisions apply to a particular volume when B30.30 is referenced and as specified in that volume.
SECTION 30-0.2: DEFINITIONS
aramid fiber: a manufactured, high modulus fiber made from a long-chain synthetic aromatic polyamide in s’hich at least 85% of the amide linkages join two aromatic rings.
birdcage: a rope condition that results in deformation with the outer strands being displaced away from the rope axis. It is usually the result ofshock loading or localized twisting In a rope (see Figure 30-0.2-1).
braid: a rope or textile structure formed by intertwining strands.
double braid: a rope constructed from an Inner hollow braided rope (core) surrounded by another hollow braided rope (cover) (also known as braid-on-braid or two-in-one braid).
single braid: rope structure consisting of multiple strands that may be intertwined in a plain or twill pattern.
crown break: a wire break located on the outside of the rope that occurs above the strand-to-strand contact points with both ends visible (see Figure 30.0.2.2).
D/d ratio: the ratio of the pitch diameter of the sheave or drum, D, to the nominal rope diameter, d (see Figure
30.0.2.3).
denier: a mass-per-unit-length measure equal to the weight in grams of 9000 m of the material. Denier is a direct numbering system in which the lower numbers represent the finer sizes and the higher numbers the coarser sizes.
design factor: the minimum breaking force of the rope in a rope system divided by the maximum static tension in the rope.
(f1) Lubrication removed during the process of adding an end termination shall be replaced in the affected areas of rope.
(g) Swaged sockets shall not be applied to fiber core rope, lang by rope, or Category 3 rotation-resistant rope.
(h) When an end fitting is to be applied to a used rope, a periodic inspection shall be performed on a length of 60 rope diameters from the rope end to be terminated. This length of rope shall have a diameter equal to or greater than the rope’s specified nominal diameter.
(I) When selecting terminations for corrosion-resistant wire rope, consideration should be made for accelerated corrosion rates in some combinations ofdissimilar metals.
(j) End terminations shall not be modified without the approval of the fitting manufacturer or LHE manufacturer.
(k) Replacement of field-installed swaged and poured running rope terminations shall be proof tested to a minimum of 95% of the L.HE’s maximum rated line pull when the termination is installed by a documented procedure. Otherwise, the swaged or poured termination shall be proof tested to 40% of minimum breaking force.
(l) The inspection of end terminations shall be performed in accordance with Section 30-1.8. For wedge socket inspection, refer to ASME B30.26 for removal criteria.
SECTION 30-1.8: ROPE INSPECTION AND
REMOVAL CRITERIA, AND
RECORDS
30-L8.1 Inspection
(a) General. All inspections shall be performed by a designated person. Any deficiencies identified shall be examined and a determination made by a qualified person as to whether they constitute a hazard and, if so. what steps need to be taken to address the hazard.
(b) Frequent
(1) RunnIng rope In service shall be visually inspected daily, unless a qualified person determines it should be performed more frequently. The visual inspection shall consist of observation of all rope that can reasonably be expected to be in use during the day’s operations. The inspector should focus on discovering gross damage that may be an immediate hazard.
(2) Specific types of damage include the following:
(-a) distortion to the uniform structure of the rope
(-b) broken wires
(-c) corrosion
(-d) gross damage or deterioration of the end connection(s)
(-e) evidence of heat, electrical, or lightning damage
(-f) localized change in lubrication condition.
