Full title and description

St ISO 10972-1-2025 — Cranes — Requirements for mechanisms — Part 1: General. This standard specifies general requirements that apply to mechanisms and related components of cranes (as defined in the ISO 4306 series), covering layout, selection and design principles for mechanism components while excluding proof-of-competence calculation rules.

Abstract

This document establishes requirements for mechanisms and related components of cranes concerning general layout and design of mechanisms and selection and/or design requirements of components. It is intended to ensure safe, reliable design and integration of crane mechanisms but does not provide requirements for proof-of-competence calculations for limit states such as yield strength, fatigue or wear.

Scope

ISO 10972-1:2025 applies to mechanisms and related components of cranes defined in the ISO 4306 series. It covers requirements for general layout and design of mechanisms and for the selection or design of components used in crane mechanisms. The standard excludes methods and rules for strength/proof-of-competence calculations for limit states (for example yield strength, fatigue and wear), which are out of scope. It is intended to be used with the other parts of the ISO 10972 series that address specific crane types.

Key topics and requirements

• General layout and overall design principles for crane mechanisms (arrangement, interfaces, and maintainability).
• Selection and design requirements for mechanism components (gears, bearings, couplings, brakes, drives and similar items) to ensure compatibility with intended duty and operating conditions.
• Requirements that support safe manufacture, mounting, installation and testing of mechanism components (where relevant to general requirements).
• Exclusions: explicit exclusion of proof-of-competence/calculation rules for strength, fatigue and wear (these are not provided in Part 1).
• Compatibility and reference intent with the ISO 4306 crane classification series and with other ISO 10972 parts addressing specific crane types.

Typical use and users

Design and engineering teams, manufacturers of crane mechanisms and components, conformity assessors, testing and installation contractors, technical committees and standards librarians will use this standard. It is referenced by engineers specifying or verifying mechanism design and by procurement and QA teams to define minimum design/selection requirements for crane mechanism components.

Related standards

ISO 10972 is a multi-part series. Relevant related parts include (examples): ISO 10972-2 (mobile cranes — mechanisms), ISO 10972-4 (jib cranes — mechanisms), ISO 10972-5 (bridge and gantry cranes — mechanisms). Users should consult the applicable Part for the particular crane type in addition to Part 1.

FAQ

Q: What is this standard?

A: ISO 10972-1:2025 is Part 1 (General) of the ISO 10972 series and sets out general requirements for mechanisms and related components used in cranes.

Q: What does it cover?

A: It covers general layout and design principles for crane mechanisms and selection/design requirements for mechanism components; it does not include strength/proof-of-competence calculation methods for limit states such as yield, fatigue or wear.

Q: Who typically uses it?

A: Crane designers and manufacturers, component suppliers, test and installation contractors, conformity assessors, and procurement/QA teams specifying mechanism requirements.

Q: Is it current or superseded?

A: The 2025 edition (Edition 2) is the current published version and replaces the withdrawn 1998 edition.

Q: Is it part of a series?

A: Yes — ISO 10972 is a multipart standard. Part 1 provides general requirements; other parts (for example Parts 2, 4 and 5) provide requirements for specific crane types.

Q: What are the key keywords?

A: Cranes, mechanisms, components, design requirements, selection, ISO 4306, brakes, gears, bearings, drives.
