Full title and description

STB BS EN 13411-5:2003 + A1:2008 — Terminations for steel wire ropes — Safety — Part 5: U-bolt wire rope grips. This European standard specifies minimum requirements for U-bolt wire rope grips manufactured from ferrous materials and the safe behaviour of grip-secured eye terminations when used as intended by the grip manufacturer.

Abstract

EN 13411-5:2003+A1:2008 defines materials, design, dimensions, marking, fitting instructions and type-testing procedures for U-bolt wire rope grips. It sets performance requirements (tensile efficiency and pulsatory fatigue), limits intended uses (e.g., not for spiral ropes or primary mine/crane hoist securing), and provides informative annexes with examples and fitting guidance. The document was prepared to support conformity with the Machinery Directive.

Scope

The standard specifies minimum requirements for U-bolt wire rope grips made from ferrous materials and for the safe behaviour of eye terminations secured by these grips for the manufacturer’s intended uses. Suitable applications include suspension of static loads and single-use lifting operations assessed by a competent person. The standard excludes use with spiral ropes and does not cover grips used as the primary securing device on mine hoists, crane hoists or for general lifting slings; informative annexes give examples and fitting instructions.

Key topics and requirements

• Materials and mechanical properties for components (U-bolt, bridge, nuts) including referenced property classes and material specifications.
• Tensile/performance requirement: a grip-secured eye termination shall withstand at least 80% of the rope’s minimum breaking force held for 5 minutes with limited slip (≤ 1 mm) under the specified test.
• Pulsatory fatigue requirement: assemblies must survive specified pulsatory loading (minimum 20 000 cycles) and then meet the tensile requirement without visible damage.
• Type testing and verification procedures (tests on each rope class and highest rope grade intended; minimum test samples; references to EN 12385 series and EN ISO test methods).
• Manufacturer marking, fitting instructions and information for use (torque values, spacing, orientation, rope grades and temperature limits) and purchaser recommendation to require supplier quality assurance (e.g., EN ISO 9001).
• Informative annexes with example grip designs, dimensions, fitting sequences and recommended torque/number of grips.

Typical use and users

Typical uses: forming grip-secured eye terminations for static suspensions and single-use lifting tasks when grips are appropriate and installed per manufacturer instructions. Typical users: manufacturers of U-bolt wire rope grips, lifting equipment designers and specifiers, rigging contractors, safety and inspection engineers, procurement and conformity/QA personnel. Regulatory and conformity tasks will reference this standard when demonstrating compliance with machinery and lifting-related safety requirements.

Related standards

EN 13411 is a multipart series on terminations for steel wire ropes (other parts include thimbles, spliced eyes, ferrule-secured eyes, socketing, wedge sockets, etc.). The standard cross-references the EN 12385 series (wire rope testing and characteristics), relevant material standards (e.g., EN ISO 898-1 for mechanical properties of fasteners) and the Machinery Directive (2006/42/EC) for essential safety requirements. National adoptions (BS EN, SIST EN, DIN EN, etc.) implement the EN text with national publication details.

FAQ

Q: What is this standard?

A: EN 13411-5:2003+A1:2008 is the European safety standard that specifies minimum requirements for U-bolt wire rope grips and for the safe behaviour of eye terminations secured with these grips; it is adopted nationally in CEN member states (for example as BS EN 13411-5:2003+A1:2008 by BSI).

Q: What does it cover?

A: It covers materials, dimensions, construction, marking, fitting instructions, type-testing methods and performance requirements (including tensile efficiency and pulsatory fatigue) for U-bolt wire rope grips, plus informative annexes with example designs and fitting guidance. It also states intended uses and limitations (e.g., not for spiral ropes or primary mine/crane hoist securing).

Q: Who typically uses it?

A: Manufacturers of grips, lifting and rigging engineers, rigging contractors, equipment specifiers, safety/compliance officers and procurement teams use the standard to design, test, specify and verify grip assemblies. Inspectors and certification bodies reference it when assessing termination performance.

Q: Is it current or superseded?

A: The document exists as EN 13411-5:2003 amended by A1:2008 (often cited as EN 13411-5:2003+A1:2008) and was adopted nationally (for example by BSI in 2009). National statuses can vary over time; the 2003 edition was updated by Amendment 1 (2008). Users should verify current national status with the relevant national standards body before relying on the text for compliance.

Q: Is it part of a series?

A: Yes — EN 13411 is a multipart series covering different types of terminations for steel wire ropes (parts include thimbles, spliced eyes, ferrule-secured eyes, socketing, U-bolt grips, asymmetric and symmetric wedge sockets, etc.).

Q: What are the key keywords?

A: U-bolt grip, wire rope clamp, wire rope termination, grip-secured eye, tensile efficiency, pulsatory fatigue, type testing, fitting instructions, EN 13411-5, BS EN 13411-5.
