Description
BS 464/EN 13411-1 Wire Rope Thimble
BS 464 wire rope thimbles are essential components used in various rigging and lifting applications to protect the eyes of wire ropes and enhance their durability. These thimbles are typically made from mild steel and are often hot-dipped or electro-galvanized to provide corrosion resistance.

  • Standards Compliance: BS 464 thimbles meet the performance requirements of the withdrawn standard BS 464 and the current BS EN 13411-1 standard, ensuring they are suitable for load-bearing applications
  • Material: Made from mild steel with a galvanized finish, these thimbles are designed to withstand harsh conditions while protecting the wire rope from abrasion and wear
  • Dimensions: Available in various sizes, typically ranging from 8mm to 64mm in diameter. The dimensions include internal measurements that may vary slightly depending on the manufacturer.

BS 464 thimbles are used in:
  • Rigging: To create loops in wire ropes that can withstand heavy loads without damaging the rope.
  • Lifting Equipment: They provide a smooth surface for the wire rope, reducing wear and tear during operation.
  • Marine Applications: Often utilized in marine environments due to their corrosion-resistant properties.

Wire rope thimbles, steel rope thimbles, cable thimbles or simply wire thimbles, are used to support wire rope eyes by creating a durable wear surface when connected to mating rigging hardware.

Thimbles are used to protect the eyes of cable, and rope slings from abrasion by providing a solid steel barrier between the fragile cable strands and the other rigging fitting used in the connection.

Main differences between BS 464 and EN 13411-1 wire rope thimbles
The main differences between BS 464 and BS EN 13411-1 wire rope thimbles primarily relate to their standards of compliance and the context in which they are used. Here’s a detailed comparison:

Standards Compliance

  • BS 464: This is an older standard that has been withdrawn. It was used for wire rope thimbles but is no longer the current reference for manufacturing and safety requirements.
  • BS EN 13411-1: This is the current European standard that outlines the performance requirements for thimbles used with wire ropes. It incorporates updated safety and performance criteria, reflecting advancements in materials and testing methods.

Material and Finish

Both standards typically specify:
  • Material: Mild steel is commonly used for both BS 464 and BS EN 13411-1 thimbles.
  • Finish: Hot-dipped galvanization is standard for corrosion resistance in both types, ensuring durability in various environments

Performance Requirements

  • Performance: Thimbles compliant with BS EN 13411-1 are designed to meet more stringent performance requirements compared to the older BS 464 standard. This includes factors like load capacity, resistance to wear, and overall safety during use

Availability and Sizing

  • Sizing: Both standards offer a range of sizes, but products labeled under BS EN 13411-1 may include newer sizes or specifications that were not available under BS 464. For example, thimbles available under BS EN 13411-1 can range from smaller diameters (6mm) to larger sizes (up to 64mm), similar to the offerings under BS 464, but with updated dimensions reflecting current manufacturing practices

Certification

  • Certification: Products manufactured to BS EN 13411-1 often come with certificates of conformity that validate their compliance with the latest standards, while those labeled as BS 464 may not provide such certification since it is a withdrawn standard. Most modern thimbles will indicate compliance with both standards, ensuring they meet current safety regulations while acknowledging the older standard for reference

In summary, while both BS 464 and BS EN 13411-1 wire rope thimbles serve similar purposes, the latter represents a more up-to-date and rigorous standard that aligns with contemporary safety practices and material technology.
