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 27546-2011 "Pulleys for Lifting Machinery". Compared with GB/T 27546-2011, except for structural adjustments and rewriting... Aside from the logical changes, the main technical changes are as follows. ---Added terms and definitions (see Chapter 3); ---The nominal diameter values for some wire ropes in Table 1 have been changed (see Table 1,.2011 edition); ---The usage conditions have been changed (see 6.1, 5.7 of the.2011 version); ---The mechanical property requirements for pulley materials have been changed (see Table 3,.2011 edition); ---The requirements for welds have been changed, including the addition of a requirement for "non-destructive testing of critical welds" (see 6.3,.2011 edition). 5.2); ---The requirement for lifting holes in the pulley spokes has been added (see 6.4.7); ---The dimensional tolerances have been changed, namely, the pulley diameter range of 70mm to 160mm has been added (see Table 4, Table 4 in the.2011 edition); ---Increased requirements for pulley load-bearing capacity (see 6.7); ---The relevant content regarding scrapping has been removed (see section 5.8 of the.2011 edition); ---The pulley hardness requirement has been increased (see 6.8); ---Experimental methods have been added (see Chapter 7); ---The inspection rules have been changed (see Chapter 8, Chapter 6 of the.2011 edition); ---The requirements for marking, packaging, transportation and storage have been changed (see Chapter 9, Chapter 7 of the.2011 edition).
