Single Hook
DIN 15401‑2 single hook finished parts are completely machined crane hooks manufactured from DIN 15401‑1 unmachined hook blanks.
Thread cutting on the shank, bearing surface finishing and final dimensional machining are fully completed. These ready‑to‑mount single hooks have undergone heat treatment, proof‑load test and mandatory inspections, and are permanently marked with strength class and working load limit for direct assembly into crane hook assemblies.

– Type RSN (Drop forged) for single hooks Nos. 1~12
– Type RFN (Hammer forged) for single hooks Nos. 16~250
Features
- High strength and toughness — achieved by forging and heat treatment, capable of heavy lifting loads.
- Refined grain structure — forging creates continuous metal flow lines for reliable performance.
- Accurate dimensions — finished by precise machining, ready for direct assembly.
- Compact and economical — simple structure, low cost, easy to maintain.
Applications
- Overhead cranes, electric hoists, and gantry cranes — mainly for lifting capacity below 80 tons.
- Single-point lifting where one sling or hook is required.
- General industrial hoisting, machine shops, and warehouse lifting equipment.
