GB 4490-1984Conveyor belts with textile carcass - Widths and lengths (English PDF)

Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009.

This standard replaces GB/T 4490-2009 "Fabric core conveyor belt width and length", compared with GB/T 4490-2009, the main technical the technical changes are as follows.

---Updated the standards involved in the scope (see Chapter 1, Chapter 1 of the 2009 edition);

--- Revised Table 3 (see Table 3, Table 3 of the 2009 edition).

The translation method used in this standard is equivalent to ISO 251:2012 "Width and Length of Fabric Core Conveyor Belt".

This standard was proposed by the China Petroleum and Chemical Industry Federation.

This standard is under the jurisdiction of the National Belt Wheel and Belt Standardization Technical Committee Conveyor Belt Subcommittee (SAC/TC428/SC1).

Drafting organizations of this standard. Wuxi Baotong Technology Co., Ltd., Sino-German (Yangzhou) Transportation Engineering Technology Co., Ltd., Zhongnan Rubber Group Co., Ltd., Shandong Yihe Rubber Conveyor Belt Co., Ltd., Shandong Xiangtong Rubber and Plastic Group Co., Ltd., Qingdao University of Science and Technology.

1 Scope

This standard specifies the width and length of the fabric core conveyor belt and the corresponding limit deviation.

This standard does not apply to the light conveyor belt specified in GB/T 39825 [1]. For the width and length limit deviations of the cutting light conveyor belt, see GB/T 39823 [2] regulations.

2 Width and limit deviation

The width and limit deviation of the conveyor belt are shown in Table 1.
