Overview

ISO 10245-5:2026, Cranes - Limiting and indicating devices - Part 5: Bridge and gantry cranes, is an international standard developed by ISO. It defines the requirements for limiting and indicating devices used on bridge and gantry cranes to enhance operational safety and reliability. These devices are designed to monitor and control loads, crane motions, overall performance, and environmental influences. This part of the ISO 10245 series builds on the general requirements outlined in ISO 10245-1, with a specific focus on the unique features and safety concerns of bridge and gantry cranes.

Key Benefits

• Enhanced operational safety for crane operators and surrounding personnel
• Systematic load and motion control to prevent overloading and hazardous movements
• Facilitated compliance with global safety and regulatory expectations

Key Topics

• Limiting Devices: Devices that automatically limit crane functions if operational parameters are exceeded, such as rated capacity limiters and motion limiters.
• Indicating Devices: Visual and audible devices that inform the operator of crane status, including capacity indicators and warning signals.
• Motion and Performance Limiters:
  • Motion limiters for hoisting, lowering, travelling, and slewing motions to avoid unsafe positions or collision
  • Backup limiters offer secondary protection if a primary limiter fails
• Multiple Hoist and Crane Configurations: Requirements for indication and control when multiple hoists or cranes operate in combination.
• Inspection and Verification: Guidelines for periodic inspection and functional verification to ensure continued compliance and reliability.
• Optional Data Logging and Event Recording: Recommendations for the use of event recorders and data loggers that track critical events and operational data for analysis and maintenance planning.

Applications

This ISO standard is essential for:

• Manufacturers of bridge and gantry cranes needing validated safety device requirements
• Crane operators and maintenance teams seeking to comply with international safety expectations and reduce risks in daily operations
• Design and engineering professionals responsible for specifying, integrating, and verifying limiting and indicating systems in crane projects
• Regulatory compliance within industries such as manufacturing, shipping, ports, steelworks, and construction, where bridge and gantry cranes play a critical role

Key applications include:

• Monitoring and enforcing load limits to prevent structural or mechanical failure
• Providing clear indicators and alarms for crane operators, especially in complex or high-risk environments
• Coordinating the operation of multiple hoists or cranes from a single control point, ensuring combined safety and performance
• Supporting inspection and incident analysis through optional data logging features

Related Standards

• ISO 10245-1: Cranes - Limiting and indicating devices - Part 1: General (foundation for requirements in all crane types)
• ISO 10245-2: Cranes - Limiting and indicating devices - Part 2: Mobile cranes
• ISO 10245-3: Cranes - Limiting and indicating devices - Part 3: Tower cranes
• ISO 10245-4: Cranes - Limiting and indicating devices - Part 4: Jib cranes
• ISO 4306-1 & ISO 4306-5: Cranes - Vocabulary (terminology references)
• ISO 8686-1: Cranes - Design principles for loads and load combinations - Part 1: General
• IEC 60204-32: Safety of machinery - Electrical equipment of hoisting machines
• IEC 61310-1: Visual, acoustic, and tactile safety signals for machinery
• IEC 62745: Cableless control system safety for machinery

By adhering to ISO 10245-5:2026, bridge and gantry crane stakeholders can ensure robust limiting and indicating systems, supporting both operational efficiency and safety in demanding industrial settings.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out through
ISO technical committees. Each member body interested in a subject for which a technical committee
has been established has the right to be represented on that committee. International organizations,
governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely
with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are described
in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the different types
of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the
ISO/IEC Directives, Part 2 (see www.iso.org/directives).
ISO draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed patent
rights in respect thereof. As of the date of publication of this document, ISO had not received notice of (a)
