Original and replacement wire rope must be chosen and installed under this section, with replacement rope selected per the recommendations of the rope maker, the equipment maker or a qualified person. Ropes other than rotation resistant types must either meet ASME B30.5-2004 at section 5-1.7.1 (other than its paragraph (c)), or be designed with enough minimum breaking force and design factor relative to rated capacity that the 1926.1413 inspections effectively prevent sudden failure. Rope must suit the safe functioning of the equipment. Boom hoist reeving may not use fiber core rope, derricks excepted. Rotation resistant rope is defined as Type I (at least 15 outer strands, at least three layers, little or no rotation), Type II (at least 10 outer strands, two or more layers, significant resistance) and Type III (no more than nine outer strands, two layers, limited resistance). All types need an operating design factor of at least 3.5. Type I needs at least 5 unless both rope and equipment makers approve otherwise in writing. Types II and III need at least 5, and when below 5 are barred from duty cycle and repetitive lifting; when used under 5 for other lifts, every lift requires a qualified person's pre-lift rope inspection (a lay with over one broken wire is treated as hazardous), operation that minimises dynamic effects, and recording of the lift in monthly and annual inspection documents for later reuse decisions. Rotation resistant rope may serve as boom hoist reeving only where load hoists act as boom hoists for luffing or boom and mast attachments, and then the drum's first layer pitch diameter and every boom hoist sheave must be at least 18 times rope diameter, 1926.1426(a) (regardless of manufacture date) and (b) must be met, listed ASME B30.5-2004 5-1.3.2 provisions apply with 18 times in place of 16 for multiple reeving sheaves, the reeving system's operating design factor must be at least five (the combined minimum breaking force of every rope part divided by the load from static structure weight plus rated load), and any power-controlled lowering system must handle rated capacities and speeds. Wire rope clips on wedge sockets go on the unloaded dead end only (purpose-built dead-end devices allowed), socketing follows the rope or fitting maker's method, and seizings are placed on both sides of a cut in the length and number the rope maker specifies.
