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 24542-2009 "Self-locking device for fall protection with rigid guide rails": Compared with GB 24542-2009, except for the structure
In addition to adjustments and editorial changes, the main technical changes are as follows:
a) Changed the scope (see Chapter 1, Chapter 1 of the:2009 edition);
b) Changed the definitions of self-locking device, rigid guide rail, steering gear and fall distance (see 3:1, 3:2, 3:4, 3:13, 3:2, 3:1,:2009 version)
3:3, 3:11);
c) The terms and definitions of safety rope, buffer, connecting rope, opening point, opening device and sliding distance are deleted (see the:2009 version of
3:4, 3:5, 3:7, 3:8, 3:9, 3:10);
d) Added self-locking device with rigid guide rail, buffer device, type A blocking device, type B blocking device, maximum rated load, minimum rated load
Terms and definitions of fixed load, bracket and locking distance (see 3:3, 3:5, 3:7, 3:8, 3:9, 3:10, 3:11, 3:12);
e) Change "General Provisions" and "General Requirements" to "Design and Structure" (see 4:1, 4:1 and 4:2 of the:2009 version);
f) Increased assembly performance (see 4:2);
g) Increased overall static performance (see 4:3:1);
h) Increased the static performance of the buffer device (see 4:3:2);
i) Increased the static performance of the blocking device (see 4:3:3);
j) Deleted the static load performance of guide rails (see 4:5 of the:2009 edition);
k) Change "overall dynamic load performance" to "dynamic performance" (see 4:4, 4:4 of the:2009 version);
l) Increased working condition performance (see 4:5);
m) Changed the technical requirements for "locking performance under special circumstances" (see 4:8, 4:8 in the:2009 version);
n) "Design and structure", "assembly performance", "dynamic performance" and "working condition performance" were added to the test method, and "overall static load test" was added:
Changed to "static performance" (see Chapter 5, Chapter 5 of the:2009 edition);
o) Change "logo" to "permanent logo" (see Chapter 7, 7:1 and 7:2 of the:2009 edition);
p) Added information provided by the manufacturer (see Chapter 8);
q) Added technical requirements and test methods for steering gear (see Appendix B):
