Foreword

This document is in accordance with the provisions of GB/T 1.1-2020 "Guidelines for Standardization Work Part 1.Structure and Drafting Rules of Standardization Documents"

Drafting.

This document replaces GB/T 25015-2010 "Transferring Winch". Compared with GB/T 25015-2010, except for structural adjustments and editorial amendments

In addition, the main technical changes are as follows.

a) The change adds some normative reference documents (see Chapter 2, Chapter 7 of the.2010 edition);

b) Some terms have been changed, and the terms of light-load tension, light-load speed, and normally closed braking device have been added (see Chapter 3,.2010 edition

Chapter 3);

c) The schematic diagrams of the left-hand moving ship winch and the right-hand moving ship winch have been changed (see 3.2.1 and 3.2.2, 4.1 in the.2010 edition);

d) The design and operation of the steel wire rope, drum length, drum flange height, automatic braking device, drum braking device, control

Device requirements (see 4.3, 4.4.2, 4.4.3, 4.6.1, 4.6.2, 4.9, 5.2.4, 5.2.6, 5.2.7, 5.2.9, 5.2.10 of the.2010 edition);

e) The requirements for safety and protection, speed control, and drive devices in design and operation have been added (see 4.7, 4.8, 4.10);

f) The performance parameter requirements such as nominal mooring speed, supporting load, wire rope breaking force, automatic tension, etc. have been changed (see 5.2, 5.5, 5.6, etc.)

5.7, 5.1.2, 5.1.3, 5.1.4, 5.3.5 of the.2010 version);

g) The requirements for performance parameters such as the load of the reel and the rope capacity of the reel have been added (see 5.1, 5.3);

h) The test and acceptance method of reel load is changed (see 6.2.3, 6.3.2, 6.2 of the.2010 edition);

i) The test and acceptance method for no-load operation has been added (see 6.2.1, 6.3.1);

j) The inspection rule requirements have been deleted (see Chapter 7 of the.2010 edition);

k) The identification method of the product model has been changed (see 7.1, 4.2 of the.2010 edition);

l) The packaging, transportation, and storage requirements have been deleted (see 8.2, 8.3, and 8.4 in the.2010 edition).
