Full title and description

ISO 10245-3:2019 — Cranes — Limiting and indicating devices — Part 3: Tower cranes. This part of ISO 10245 specifies requirements and performance criteria for limiting and indicating devices that are specific to tower cranes (as defined in ISO 4306‑3). It supplements the general requirements given in ISO 10245‑1 and excludes end stops used only for erection/dismantling or configuration changes.

Abstract

This International Standard gives requirements specific to tower cranes for rated-capacity limiters and indicators, motion and performance limiters and indicators, and associated functions and responses. It is intended to ensure safe operation by restricting loads, motions and speeds and by providing appropriate visual and audible warnings; it does not apply to certain end stops or to erection/dismantling operations.

Scope

Specifies requirements for limiting and indicating devices that are specific to tower cranes: rated-capacity limiters and indicators, motion and performance limiters/indicators (hoisting, lowering, travelling, trolleying, luffing, etc.), and the required responses, resets and fail-safe behaviour. The standard applies to tower cranes as defined in ISO 4306‑3 and is not applicable to simple end stops (buffers) used only to stop trolleying, travelling or luffing, nor to erection/dismantling operations or crane reconfiguration. General device requirements remain in ISO 10245‑1.

Key topics and requirements

• Rated-capacity limiters: design and activation criteria for limiting devices that prevent overload; required response characteristics and prohibition of operator override during normal operation.
• Rated-capacity indicators: performance of indicators and warning thresholds (approach and overload warnings) including visual and audible signalling.
• Motion limiters: required motion limiters for hoisting, lowering, trolleying, travelling, luffing and other motions listed in the standard; secondary/back-up limiter requirements and controlled reset actions.
• Performance limiters: speed/performance limiting where risk of exceeding design speeds exists; classification of limiters versus indicators.
• Functional responses: required behaviour on reaching limits (e.g., warnings, gradual slowdown or stop), reset and testing provisions, and requirements for preventing unintended reset or easy operator defeat.

Typical use and users

Used by crane manufacturers, designers, safety engineers, test houses, regulatory bodies and equipment owners/operators to design, install, test and verify limiting and indicating devices on tower cranes. It is referenced in conformity assessments, safety procedures, purchase specifications and maintenance testing for tower crane equipment.

Related standards

ISO 10245‑1 (general requirements for limiting and indicating devices) — provides the overarching principles and general device requirements. ISO 4306‑3 (crane classification and terminology; definition of tower cranes) is referenced for scope. Other parts of ISO 10245 (where applicable) and national crane safety standards may be used alongside this part for complete compliance.

FAQ

Q: What is this standard?

A: ISO 10245‑3:2019 is the third edition (2019) of the part of ISO 10245 that sets requirements for limiting and indicating devices specifically for tower cranes. It supplements the general requirements in ISO 10245‑1.

Q: What does it cover?

A: It covers rated-capacity limiters and indicators, motion and performance limiters and indicators applicable to tower cranes, required responses and reset behaviour, and which devices or situations are excluded (for example certain end stops and erection/dismantling operations).

Q: Who typically uses it?

A: Crane manufacturers, designers, safety and test engineers, certification bodies, owners/operators and procurement specialists who need to ensure limiting/indicating devices on tower cranes meet internationally accepted safety and performance criteria.

Q: Is it current or superseded?

A: ISO 10245‑3:2019 is the current (third) edition published in 2019; it replaced the 2008 edition. ISO standards are typically reviewed every five years and the published status as of the 2019 edition is “Published.” Users should confirm in the ISO catalogue or their national standards body for any subsequent confirmations or amendments.

Q: Is it part of a series?

A: Yes — it is Part 3 of the ISO 10245 series (Limiting and indicating devices). Part 1 contains general requirements; other parts address different crane types or related device requirements. The document also cross-references ISO 4306‑3 for tower crane definitions.

Q: What are the key keywords?

A: Tower crane, limiting device, indicating device, rated-capacity limiter, motion limiter, performance limiter, overload indicator, speed limit, crane safety, ISO 10245.
