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
