Overview
ISO 12210:2021 - "Cranes - Anchoring devices for in-service and out-of-service conditions" specifies requirements for anchoring devices used to control position and prevent undesirable motion of cranes and crane parts (as defined in ISO 4306-1). The standard focuses on anchoring under normal operation, sudden wind gusts that exceed in-service design values, and out‑of‑service/storm situations. It is intended to guide selection, design and documentation of crane anchoring solutions for safety and reliability.
Key topics and technical requirements
- Scope and definitions: Anchoring devices are defined to include items such as rail clamps, rail brakes, wheel brakes, braking wedges, boom latches, anchor pins and tie‑downs.
- Design loading: Devices must withstand forces from dead and live loads, wind and other environmental factors, and comply with wind assessment and load combination principles in ISO 4302 and the ISO 8686 series.
- Power independence: The holding action of anchoring devices should not require continuous power supply, ensuring effectiveness during power loss or storms.
- Actuation: Anchoring devices shall be actuated automatically or by the crane operator when wind speed exceeds the in‑service design value (per ISO 8686‑1). Mechanisms must:
- Provide holding at any track position, or
- Offer alternative means that reliably hold crane components (trolley, boom, slewing device) in anchoring positions.
- Crane‑type and motion requirements: The standard specifies which motions typically require anchoring for specific crane types (portal/semi‑portal, derrick, pillar jib, gantry, bridge). For example, travelling and slewing are mandatory for certain out‑of‑service or sudden‑wind conditions; other motions may be optional or not required.
- Information and documentation: Manufacturers/suppliers must provide design and usage parameters, plus instructions for operation, testing, maintenance and repair so crane manufacturers and owners can select components with appropriate safety margins and service life.
Applications and users
ISO 12210:2021 is practical for:
- Crane manufacturers and designers specifying anchoring and braking systems
- Procurement teams preparing technical specifications for cranes and anchoring components
- Safety engineers and risk assessors evaluating wind and storm resilience
- Maintenance teams and inspectors establishing testing and maintenance regimes
- Asset owners planning storm preparedness and out‑of‑service procedures
Typical uses include selecting rail clamps/anchor pins, designing fail‑safe anchoring systems that operate without continuous power, and documenting testing/maintenance schedules for compliance and safe operation.
