Introduction

The standardization of terminology is the basis of standardization activities. GB/T 6974 is a terminology standard in the field of cranes.

standardization level, ensure the consistency and logical integrity of terminology, improve the coordination between concept systems and terminology in different languages, and promote GB/T 6974 (all parts) "Crane Terminology" and GB/T 20863 (all parts) "Crane Classification", GB/T 3811 "Crane Design Specification", GB/T 22437 "Crane Loads and Load Combinations" Design Principles", GB/T 30024 "Capacity Verification of Metal Structures of Cranes", GB/T 30561 "Crane Rigid Bridge and Gantry Cranes" The standards such as GB/T 6974 and GB/T 6974 together constitute the basic national standard system for cranes. GB/T 6974 is planned to consist of nine parts.

— Part 1: General terms. The purpose is to standardize the general terms and definitions applicable to the crane industry.

— Part 2: Mobile cranes. The purpose is to standardize the terms and definitions related to mobile cranes.

— Part 3: Tower cranes. The purpose is to standardize the terms and definitions related to tower cranes.

— Part 4: Jib cranes. The purpose is to standardize the terms and definitions related to jib cranes.

— Part 5: Bridge and gantry cranes. The purpose is to standardize the terms and definitions related to bridge and gantry cranes.

— Part 6: Railway cranes. The purpose is to standardize the terms and definitions related to railway cranes.

— Part 7: Floating cranes. The purpose is to standardize the terms and definitions related to floating cranes.

— Part 8: Cable cranes. The purpose is to standardize the terms and definitions related to cable cranes.

— Part 9: Electrical. The purpose is to standardize the terms and definitions related to crane electrical equipment.

With the continuous development of cable crane products and the continuous advancement of technology, the terminology related to cable cranes has also changed with the products.

Development and technological progress are expanding. It is necessary to standardize and unify in a timely manner to guide the application of cable crane products.

GB/T 6974.14-1986 makes it more normative and practical to meet the technical development requirements of cable cranes.
