ISO 10245-5:2026 is an International Standard from ISO for bridge and gantry cranes. It specifies requirements for devices that limit or indicate loads, motions, performance and environment, and it is used together with ISO 10245-1 for the general crane requirements.

What does ISO 10245-5:2026 specify?

ISO 10245-5:2026 sets out how limiting and indicating devices are to be applied to bridge and gantry cranes. It covers the device requirements for loads, motion, performance and warnings, while the general requirements for all crane limiting and indicating devices are taken from ISO 10245-1.

The document is organized into five clauses and one informative annex:

• Clause 1 Scope
• Clause 2 Normative references
• Clause 3 Terms and definitions
• Clause 4 Safety requirements, including protective and risk reduction measures
• Clause 5 Inspection or verification requirements
• Annex A - Event recorder and data logger

What are the key requirements of ISO 10245-5:2026?

Rated capacity control

ISO 10245-5:2026 requires rated capacity limiters to keep each lifting mechanism within its rated capacity. In practice, that means the crane control system must prevent overload, even when several hoists or lifting mechanisms are used together.

For cranes whose rated capacity changes with load position, the standard also requires a rated capacity indicator. This matters because the operator must be told when the allowed load has been reached or when the limiter has acted.

Motion and performance limiting

ISO 10245-5:2026 requires motion limiters for the crane motions listed in Table 1, with the exact combination depending on the motion and the crane speed. For example, the table distinguishes between slow down limiters, stop limiters, backup limiters and mechanical end stops, so the designer has to select the right mix for each motion.

The standard also covers high-risk applications and collision situations. It calls for anti-collision considerations where two cranes or crane parts may collide, and it requires extra care where one motion limiter must also stop other linked motions.

Performance limiters are to be provided according to the application, and vertical motions with variable speed control need overspeed detection. In practice, this means the crane must not rely only on the operator to avoid unsafe speed or movement.

Indicators and combined controls

ISO 10245-5:2026 requires visual indicators when multiple hoists can be selected and operated from one control device. The operator must be able to see which hoist or which crane has been selected, so the wrong unit is not moved by mistake.

Where several cranes are designed to work in combination, the same principle applies. If one limiting device is activated in a common-control arrangement, the resulting motion must stop for all linked cranes.

Inspection and optional recording

ISO 10245-5:2026 links inspection and verification to the manufacturer’s or supplier’s information for use. That gives users a clear reference for planning checks on limiting and indicating devices.

Annex A adds optional guidance on an event recorder and a data logger. This is useful where owners want recorded evidence of overloads, bypasses, configuration changes or maintenance-related data.

What terms does ISO 10245-5:2026 define?

• Mechanical end stop - a physical barrier that restricts the range of motion.
• Buffer - a shock-absorbing device that can be fitted to a mechanical end stop or the moving counterpart.
• Slow down limiter - a device that initiates speed reduction and limits the speed to the desired level.
• Stop limiter - a device that initiates stopping and motion limitation.
• Backup limiter - a limiter that acts only if the primary limiting means fail.
• High-risk application - an application where possible harm is more severe, for example because of chain reaction, thermal energy or hazardous substances.
• Event recorder - a device that monitors and records load-related and geometric data when defined events occur.
• Data logger - a device that records data automatically, including data beyond event-triggered records.

Who uses ISO 10245-5:2026?

ISO 10245-5:2026 is used by crane manufacturers, control-system designers, suppliers of limiting and indicating devices, inspection personnel, and crane owners or operators. It is especially relevant for bridge and gantry cranes in settings where load control, motion control, coordinated crane operation and recorded event data matter.

What changed in ISO 10245-5:2026 from the previous edition?

ISO 10245-5:2026 cancels and replaces ISO 10245-5:1995. The stated changes are:

• alignment with ISO 10245-1
• rearranged structure and headings to match ISO Guide 78 and ISO 10245-2, ISO 10245-3 and ISO 10245-4
• updated Figure 1 for clarification
• updated Table 1 for clarification
• added 4.4.1 and 4.4.2 on indicators for multiple hoists and multiple crane combinations
• added Clause 5 on inspection or verification
• added Annex A on event recorder and data logger

Which standards are used with ISO 10245-5:2026?

Standard	What it contributes
ISO 10245-1:2021	General requirements for limiting and indicating devices for cranes
ISO 4306-1	General crane vocabulary
ISO 4306-5	Vocabulary for bridge and gantry cranes
ISO 8686-1:2012	Design principles for loads and load combinations, used in capacity-related provisions
IEC 60204-32:2023	Signal and electrical equipment references used in notes and the annex
IEC 61310-1	Requirements for visual, acoustic and tactile signals
IEC 62745:2017	Coordinated control systems for linked crane motions
ISO 10245-2, ISO 10245-3, ISO 10245-4	Companion parts covering mobile cranes, tower cranes and jib cranes

What does the ISO 10245-5:2026 document contain?

The document includes a capacity-setting relationship in Clause 4.2.2.3, a selection table for motion limiters in Table 1, and examples of rated-capacity limitation in Figure 1. These parts are used when designing or checking how the crane reacts to overload, speed reduction, stopping and restricted movement.

It also contains practical requirements for warning signals, coordinated stopping of multiple hoists or cranes, and the reset behavior of backup limiters. Annex A gives optional guidance on event recorders and data loggers for recording operational and configuration data.
