This document adds a chapter on "Normative References".

Introduction

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

To improve the standardization level of cranes, ensure the consistency and logical integrity of terminology, and improve the terminology between concept systems and different languages.

GB/T 6974 is planned to consist of 9 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.

3 Terms and definitions

The following terms and definitions apply to this document.

Tower CraneTower Crane A power-driven slewing jib crane with the jib located at the top of a tower which remains substantially vertical in the working position.

Note. Tower cranes are equipped with devices for lifting and lowering suspended loads and moving the load by luffing, slewing or traveling as a whole. Some tower cranes only partially realize Actions instead of all actions.

3.1.1

Assembled tower craneTower crane erected from parts Tower cranes (3.1) that are transported to the site in parts and erected using separate lifting equipment.

The design allows it to remain in the installed position when not in operation and be disassembled and moved to another site.

3.1.2

Self-erecting tower crane A tower crane (3.1) that is transported to the site and does not require the use of separate lifting equipment for almost all of its erection.

The design allows it to remain in place when not in operation and be lowered and moved to another site.

3.1.3

Mobile self-erecting tower crane mobile self-erecting tower crane Self-erecting tower cranes (3.1.2) mounted on a self-propelled or trailer-mounted chassis.
