Foreword
This document complies with the provisions of GB/T 1.1-2020 "Standardization Work Guidelines Part 1.Structure and Drafting Rules of Standardization Documents"
Drafting.
This document replaces GB/T 20119-2006 "Flat Steel Wire Rope for Balancing". Compared with GB/T 20119-2006, except for structural adjustment and compilation
In addition to editorial changes, the main technical changes are as follows.
---Added 18 round steel wire rope structures such as 18×7, 34(M)×7, 30×P6-6×19M and PDCR8×[4×12M], etc.
2 flat wire rope structures (see Chapter 4);
--- Added corresponding technical requirements such as the nominal diameter of structural steel wire ropes such as 18×7, 34(M)×7, PDCR8×[4×12M] (see
Chapter 7);
---Increased the weight coefficients of 18×19, 34(M)×19, 35(W)×7 and other categories of steel wire ropes (see Table 5);
---Added the reference weight of the flat steel wire rope after oiling (see 7.6.2, Table A.10);
--- Added conditions for judging the qualification of round steel wire rope split wires (see 9.1).
