DIN 15402‑2 ramshorn hook finished parts are ready‑to‑install forged double‑hook components converted from DIN 15402‑1 unmachined hook blanks. All machining work including shank thread cutting, bearing surface finishing and dimensional fine‑tuning has been completed. Each finished hook passes heat‑treatment, proof‑load test and full‑range inspections, and is permanently marked with strength class and working load limit according to DIN requirements for heavy‑duty balanced hoisting operations.
Key Features of DIN 15402‑J2 Ramshorn Hook Finished Parts
- Symmetrical double‑throat ramshorn structure achieves balanced load distribution for two‑sling lifting, lowering sling extrusion risk under heavy‑load conditions.
- Fully‑machined threaded shank and precise bearing seat guarantee perfect matching with hook nut and crosshead assembly, stable and reliable connection for crane hook blocks.
- Complete quenching‑and‑tempering heat‑treatment delivers stable mechanical properties, high strength and good toughness for heavy‑duty cyclic hoisting work.
- Every finished hook undergoes mandatory proof‑load test, visual inspection and dimensional check; permanent marking of strength grade and WLL ensures full product traceability.
- Available with or without nose design, compatible with multiple hook‑block configurations; safety latch can be equipped to prevent sling slipping off the hook throat.
- Strictly manufactured complying with DIN 15402‑2 standard, widely accepted for European‑style overhead cranes, gantry cranes and port hoisting equipment.
Main Industrial Applications
- Heavy‑duty overhead and gantry cranes: Mainly for large‑tonnage cranes above 50 tons requiring balanced two‑sling hoisting.
- Port and dock machinery: Portal cranes, container handling equipment and heavy‑load harbour lifting devices.
- Metallurgical industry: Foundry cranes for lifting steel ladles and heavy hot‑work structural components.
- Heavy‑duty machinery manufacturing: Large‑equipment assembly workshops for balanced lifting of oversized workpieces.
- Crane OEM supply: Direct ready‑for‑assembly hook components for crane manufacturers following DIN / EN 1677 specifications.
Important Note
DIN 15402‑2 finished ramshorn hooks can be directly assembled into hook blocks and put into lifting service. Do not modify thread, hook throat or bearing surface by welding or grinding, otherwise the hook’s safety performance will be invalidated.
