1.10.2 Winding Drum Machines
Suspension ropes shall be replaced on winding drum machines if any of the following applies:
(a) The broken crown wires are equally distributed among the strands, when the number of broken wires per rope lay in the worst section of rope exceeds 12.
(b) The brokencrownwires predominate inoneortwo strands, when the number ofbroken wires per rope lay in the worst section of rope exceeds 6.
(c) There is more than one valley break per rope lay.
(d) There are any valley breaks at any location where rouge exists.
1.10.3 All Elevator Types
The suspension, compensation, and governor ropes shall be replaced when their actual diameter is reduced below the value shown in Table 1.10.3-1. For nominal diameters not listed in Table 1.10.3-1, the minimum diameter reduction shall be calculated using the criteria outlined in Table 1.10.3-1, General Notes (a) and (b). Normal wear diameters, unfavorable wear, and rouge conditions as listed in the table shall apply.
Measurement for diameter shall be taken on a straight portion ofrope at the worst location. Two measurements at the same position at right angles shall be taken. The ropes shall be replaced if both of these measurements are below the replacement value. However, if only one of the measurements is below the replacement value, then the criteria for wire breaks under “Unfavorable Wear Conditions” shall apply. See Table 1.10.1.2-1.
1.10.5 Replacement of a Single Suspension Rope
If one rope of a set is worn or damaged and requires replacement, the entire set of ropes shall be replaced; except, where one rope has been damaged duringinstalla- tion or acceptance testing prior to being subjected to elevator service, it shall be permissible to replace a single damaged rope with a new rope, provided that the requirements of 1.10.4.4 and of 1.10.5.1 through 1.10.5.1.6 are met.
NOTE: Damage includes but is not limited to kinked ropes.
