TS ISO 4306-3

TS ISO 4306-3 is the tower crane part of the ISO 4306 vocabulary series for cranes. It provides the general definition of a tower crane and sets out the terminology used for each type of tower crane, using figures with referenced term numbers. In practice, this kind of vocabulary standard helps the industry use the same names for the same technical concepts.

Which tower crane types are covered

According to the scope, the standard applies to tower cranes that can be assembled and dismantled, including element-assembled and self-erecting cranes, permanently erected tower cranes, and mobile self-erecting tower cranes. In general technical terms, tower cranes are lifting machines designed to handle loads at height, especially on construction sites where reach, lifting height, and a stable tower structure are important. This document addresses terminology rather than performance limits or design calculations.

What is outside the scope

• Mobile cranes are excluded.
• Erection masts, with or without jibs, are excluded.
• The referenced term numbers linked to figures help tie each named feature to a consistent visual reference across tower crane types.

As a result, TS ISO 4306-3 is most useful as a shared technical language for designers, manufacturers, drafters, trainers, and maintenance teams working with tower cranes. Its main value is conceptual clarity: it reduces ambiguity when describing crane types and their components across documents, drawings, and discussions.
