Hook

  • Quad Hook Machined fitted with Nut, Crosshead and Bearing

    Quad Hook

    A DIN 15402C Quad Hook (also known as a four-prong hook) is a heavy-duty lifting component engineered to German industrial standards (DIN) for use in demanding crane applications. Typically used for very heavy lifts, ranging from 160 tons up to 4000 tons, with equalized loads on all four prongs.

    – Hook, nut and crosshead forged, heat treated and thread fully machined as per DIN15403 design

    – Material: super alloys

    – Mechanical properties:  V

    – Load test: requested/recommended after machining

    – Certificate: EN10204-3.1

    – Standard: DIN 15402-C

  • Ramshorn Hook

    Ramshorn Hook

    DIN 15402‑2 ramshorn hook finished parts are fully‑machined forged lifting hooks converted from DIN 15402‑1 unmachined hook blanks.

    Complete machining including shank thread cutting, bearing surface finishing and dimensional fine‑tuning has been finished. These ready‑to‑install hooks have passed heat‑treatment, proof‑load test and required inspections, and are marked with strength class and working load limit for direct assembly into crane hook suspensions.

    – Hook, Nut and Crosshead forged, heat-treated and thread fully machined as per DIN15403 design

    – Material: carbon, alloys

    – Mechanical properties: M, P, S, T, V

    – Load test: requested/recommended after machining

    – Certificate: EN10204-3.1

    – Standard: DIN 15402 or GB /T 10051

    – Type RSN (Drop forged) for single hooks Nos. 1~12

    – Type RFN (Hammer forged) for single hooks Nos. 16~250

  • Ramshorn Hook Unmachined

    Ramshorn Hook Unmachined

    DIN 15402‑1 ramshorn hook unmachined parts are drop‑forged or hammer‑forged hook forgings after forging and heat treatment, without thread cutting and final machining.

    They serve as raw forgings for subsequent machining to produce finished threaded‑shank ramshorn crane hooks complying with DIN 15402‑2.
