TS ISO 4306-3

TS ISO 4306-3 is a terminology standard for tower cranes, setting out the commonly used terms and their definitions in this field. Its purpose is to support a shared technical language for identifying tower crane types and related concepts. The focus is on naming and conceptual clarity rather than on performance requirements or design specifications.

How tower-crane terminology is organised

In general engineering use, tower cranes are lifting machines associated with tall structures, large hook heights and broad working radii. Typical technical vocabulary around this subject covers the tower, jib, slewing unit, counterweight arrangement and hoisting system, together with the distinctions used to describe different tower-crane configurations. A vocabulary standard helps align these terms so that manufacturers, engineers, operators and maintenance teams use the same wording with the same meaning.

According to the supplied scope, this standard gives the general definition of a tower crane and the terminology for each type of tower crane. That means it is primarily a language-and-classification document: it supports consistent documentation, comparison of sources and clear distinction between equipment categories, rather than prescribing test methods, numerical limits or construction rules.

• Provides a common set of tower-crane terms and definitions.
• Includes the general definition of a tower crane and terminology for its types.
• Supports consistent technical communication in lifting equipment practice.
• Emphasises vocabulary and classification rather than performance testing.
• Listed as a withdrawn standard, so it functions as a historical terminology reference.
