Introduction

The standardization of terminology is the basis of standardization activities: GB/T 6974 is the terminology standard in the professional field of cranes: Standardization level, ensuring the consistency and logical integrity of terminology, improving the coordination between conceptual systems and terminology in different languages, and promoting Technical exchanges and business cooperation play an important role: GB/T 6974 is planned to consist of 9 parts: ---Part 1: General terms: The purpose is to standardize common terms and definitions applicable to the crane industry: ---Part 2: Mobile cranes: The purpose is to standardize terms and definitions related to mobile cranes: ---Part 3: Tower cranes: The purpose is to standardize terms and definitions related to tower cranes: ---Part 4: Jib crane: The purpose is to standardize terms and definitions related to jib cranes: ---Part 5: Bridge and gantry cranes: The purpose is to standardize terms and definitions related to bridge and gantry cranes: ---Part 6: Railway cranes: The purpose is to standardize terms and definitions related to railway cranes: ---Part 7: Floating cranes: The purpose is to standardize terms and definitions related to floating cranes: ---Part 8: Cable cranes: The purpose is to standardize terms and definitions related to cable cranes: ---Part 9: Electrical: The purpose is to standardize terms and definitions related to crane electrical matters: The earliest terminology national standard released in the crane professional field is GB/T 6974 "Terminology for Hoisting Machinery" released in 1986, including Including GB/T 6974:1~6974:19, a total of 19 standards: Later, our country implemented standard update iterations and transformed the international standard ISO 4306 During the process of "Crane Terminology", some standards were replaced and abolished, but there are still GB/T 6974:15-1986 "Hoisting Machinery Terminology": Hanging Monorail System", GB/T 6974:16-1986 "Terminology for Hoisting Machinery Metallurgical Crane", GB/T 6974:17-1986 "Name of Hoisting Machinery Terminology for Stacking Crane", GB/T 6974:18-1986 "Terminology for Hoisting Machinery Port Crane" and GB/T 6974:19-1986 A total of five bridge and gantry crane terminology standards in "Hoisting Machinery Terminology and Container Cranes" have not been replaced: Although my country issued in:2008 GB/T 6974:5-2008 "Crane Terminology Part 5: Bridge and Gantry Cranes" was published, but this standard is equivalent to ISO 4306-5: The:2005 "Crane Terminology Part 5: Bridge and Gantry Cranes" does not replace the above five national standards, nor does it completely cover the content: build: Therefore, the terminology in the professional fields of bridge and gantry cranes in my country has emerged in a multi-standard parallel situation: In order to change this situation, GB/T 6974:5-2008 "Crane Terminology Part 5: Bridge and Gantry Cranes" and the above five items The standards have been consolidated and revised: This not only unified and standardized the terms and definitions of bridge and gantry cranes, but also optimized and improved my country's crane technology: language standard system: The revised standards are more scientific, operable and advanced: This revision, combined with the latest technological development and actual use of bridge and gantry cranes in my country, defines bridge and gantry cranes: Terminology and definitions of the complete machine, mechanism and parts, characteristic parameters, etc:, in order to realize the integration of my country's bridge and gantry cranes with international standards and promote It has laid a solid foundation for promoting technological exchanges between my country's crane industry and countries around the world, reducing technical trade barriers, and adapting to the needs of international trade: Base: Crane terminology Part 5: Bridge and gantry cranes
