Overview

EN 13411-5:2003+A1:2008 - Terminations for steel wire ropes - Safety - Part 5: U-bolt wire rope grips is a CEN European Standard that specifies minimum safety, material and testing requirements for U-bolt grips used to form grip-secured eye terminations on steel wire ropes. The standard supports conformity with the essential safety requirements of the Machinery Directive and associated EFTA regulations. It covers manufacture, marking, fitting instructions, and type testing to ensure consistent performance and safe use.

Key topics and technical requirements

• Scope and limitations
  • Applies to U-bolt wire rope grips manufactured from ferrous materials.
  • Not suitable for spiral ropes and not intended as primary securing devices on mine or crane hoists or for general lifting slings.
• Materials and mechanical properties
  • U-bolt: carbon steel, property class ≥ 5.8 and ≤ 8.8 (EN ISO 898-1).
  • Bridge: malleable cast iron (W40-05 or B35-10 per EN 1562) or forged non‑ageing carbon steel.
  • Nuts: carbon steel, property class ≥ 5 (EN 20898-2) and product grade A (EN ISO 4759-1).
• Performance requirements
  • Grip-secured eye termination must withstand at least 80% of the rope’s minimum breaking force for 5 minutes with ≤ 1 mm slip.
  • Fatigue requirement: at least 20,000 cycles under pulsatory loading.
  • Cyclic test parameters: cyclic tension between 15% and 30% of the rope’s MBF; initial preload often 20% with possible re‑tightening per manufacturer; frequency ≤ 5 Hz.
• Type testing and verification
  • Tests on each rope class and the highest rope grade intended; minimum of three assemblies for type testing.
  • Test procedures reference EN 12385 series and EN ISO 7500‑1 for test machine verification.
• Information for use
  • Mandatory manufacturer marking (grip size and identification) and comprehensive fitting instructions including torque values, spacing, orientation, rope grades and temperature range.
  • Purchasers are advised to require supplier quality assurance (e.g., EN ISO 9001) in procurement contracts.

Applications and who uses this standard

• Practical uses: forming safe eye terminations for static suspension and single-use lifting operations where grips are suitable and manufacturer instructions and safety factors have been applied.
• Typical users: manufacturers of U-bolt wire rope grips, lifting equipment specifiers, safety engineers, rigging contractors, purchasers and conformity/QA teams ensuring compliance with the Machinery Directive.

Related standards

• EN 13411 series (other parts: thimbles, splicing, ferrules, sockets)
• EN 12385-1 / EN 12385-2 (steel wire ropes)
• EN ISO 898-1, EN 1562, EN ISO 4759-1, EN ISO 7500-1, EN 292-2, EN 1050

Specify EN 13411-5 compliance and the supplier’s QA system in contracts to ensure consistent product quality and safe operation.
