前言

本文件按照GB/T1.1—2020《標準化工作導則第1部分：標準化文件的結構和起草規則》的規

定起草。

本文件是GB/T6974《起重機術語》的第3部分。GB/T6974已經發布了以下部分：

——第1部分：通用術語；

——第2部分：流動式起重機；

——第3部分：塔式起重機；

——第4部分：臂架起重機；

——第5部分：橋式和門式起重機；

——第6部分：鐵路起重機；

——第7部分：浮式起重機。

本文件代替GB/T6974.3—2008《起重機術語第3部分：塔式起重機》，與GB/T6974.3—

2008相比，除結構調整和編輯性改動外，主要技術變化如下：

a）更改了范圍（見第1章，2008年版的第1章）；

b）增加了術語“組裝式塔式起重機”“自行架設式塔式起重機”和“流動式自行架設的塔式起重

機”及其定義（見3.1.1、3.1.2和3.1.3）；

c）更改了不同類型的塔式起重機的示例圖（見第5章，2008年版的第4章）。

本文件等同采用ISO4306?3：2016《起重機術語第3部分：塔式起重機》。

本文件增加了“規范性引用文件”一章。

請注意本文件的某些內容可能涉及專利。本文件的發布機構不承擔識別專利的責任。

引言

術語的標準化是標準化活動的基礎。GB/T6974《起重機術語》作為起重機專業領域的術語標

準，在提升起重機標準化水平，保證術語的一致性和邏輯的完整性，提升概念體系間以及不同語種術語

間的協調性，促進技術交流和商貿合作等方面發揮著重要作用。GB/T6974擬由9個部分構成。

——第1部分：通用術語。目的在于規范適用于起重機行業領域的通用術語和定義。

——第2部分：流動式起重機。目的在于規范流動式起重機相關的術語和定義。

——第3部分：塔式起重機。目的在于規范塔式起重機相關的術語和定義。

——第4部分：臂架起重機。目的在于規范臂架起重機相關的術語和定義。

——第5部分：橋式和門式起重機。目的在于規范橋式和門式起重機相關的術語和定義。

——第6部分：鐵路起重機。目的在于規范鐵路起重機相關的術語和定義。

——第7部分：浮式起重機。目的在于規范浮式起重機相關的術語和定義。

——第8部分：纜索起重機。目的在于規范纜索起重機相關的術語和定義。

——第9部分：電氣。目的在于規范起重機電氣相關的術語和定義。
