ISO/PRF 10245-4

• Abstract:

  ISO 10245-4:2004 specifies the requirements for devices which limit and/or indicate the loads, motions, performance and environment of jib-type cranes as defined in ISO 4306-1, other than offshore, tower, mobile and railway cranes, which are covered in the other parts of ISO 10245.

Overview

ISO/PRF 10245-4:2026 is an international standard developed by ISO that specifies requirements for limiting and indicating devices installed on jib cranes. These devices are essential for monitoring and controlling crane operations, ensuring safety, and enhancing performance by indicating or limiting loads, motions, and environmental factors specific to jib-type cranes. The standard is applicable to various types of jib cranes excluding offshore, tower, mobile, and railway cranes, which are addressed in other parts of the ISO 10245 series. By following this standard, organizations can ensure compliance with safety guidelines and improve the operational reliability of jib cranes.

Key Topics

• Limiters and Indicators: ISO/PRF 10245-4 details the requirements for various limiters and indicators, such as rated capacity limiters, hoisting and lowering limiters, luffing limiters, wind speed indicators, anti-collision devices, and slewing limiters.
• Rated Capacity Limiter and Indicator: These devices are required on all jib cranes with a rated capacity of 1 ton or higher or an overturning moment above 40,000 N·m. The limiter prevents operation above safe load limits, while the indicator warns operators visually or audibly as the crane approaches its capacity.
• Motion and Performance Devices: The standard covers settings and functional expectations for devices that control or monitor crane movement and performance. These include radius or boom-angle indicators where relevant, and provide automatic prevention of dangerous motion.
• Event Recorder and Data Logger: Annex A offers guidance for the implementation of event recorders and data loggers. These support real-time monitoring, record operational history, facilitate incident analysis, and help ensure maintenance and compliance.
  • Event Recorders: Capture detailed records when abnormal events occur, such as overloads or control overrides.
  • Data Loggers: Continuously record operational and load data for a set period to support maintenance and incident investigation.

Applications

ISO/PRF 10245-4 has practical applications in various sectors where jib cranes are employed, including manufacturing, logistics, construction, port operations, and heavy equipment maintenance. Adherence to this standard provides several key benefits:

• Enhanced Safety: By specifying mandatory use of limiting and indicating devices, the standard reduces the risk of accidents related to overloading, improper operation, or environmental hazards.
• Regulatory Compliance: Helps organizations meet national and international safety regulations for cranes, reducing liability and improving market access.
• Operational Efficiency: The provision of real-time information and event/data recording allows for better maintenance planning, reduced downtime, and increased equipment lifespan.
• Data Integrity: Requirements for tamper-resistance and automatic event logging ensure that operational records are reliable for auditing and forensic purposes.

Use of event recorders and data loggers is especially valuable for risk management, as it allows for both preventive maintenance and thorough analysis in the event of incidents.

Related Standards

To ensure comprehensive compliance and safety in crane operations, the following related standards should be considered alongside ISO/PRF 10245-4:

• ISO 10245-1: Cranes - Limiting and indicating devices - Part 1: General provisions for various crane types.
• ISO 4306-1: Cranes - Vocabulary - Part 1: General terminology for crane-related equipment.
• ISO 4306-4: Cranes - Vocabulary - Part 4: Definitions specifically for jib cranes.
• Additional parts of the ISO 10245 series (covering offshore, tower, mobile, and railway cranes) for organizations operating multiple crane types.

These standards can be found through the ISO Online Browsing Platform and should be referenced for consistent terminology, broader context, and supporting requirements.

By implementing ISO/PRF 10245-4:2026, stakeholders ensure that jib cranes are equipped with essential limiting and indicating devices, supporting safer, more efficient, and compliant lifting operations.

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
