Forged Single Hook Blank

NO.2.5–NO.250 (DIN 15401) | 2.5t–5000t (non-standard) Every TUOKE single hook blank is forged, delivering high strength, high hardness, and a sound structure free of sand inclusions and cracks.

Forged Double Hook Blank

Every TUOKE double hook blank is forged, delivering high strength, high hardness, and a sound structure free of sand inclusions and cracks. A forged double hook blank is a semi-finished twin-prong crane hook component that is further machined into a finished double hook for heavy-duty hook block assemblies. TUOKE manufactures high-quality double hook blanks using precision forging processes, designed for cranes and hoisting equipment where balanced load distribution and high lifting capacity are critical. Double hooks feature two symmetrically arranged hook prongs that share the working load, resulting in significantly better force distribution than single hooks. This makes forged double hooks the preferred choice for heavy-duty lifting applications in steel mills, shipyards, heavy machinery manufacturing, and other industrial settings. Why Choose Forged Double Hooks? Superior load distribution — twin prongs evenly share the load, reducing stress concentration and extending service life No cracks or porosity — the forging process creates a continuous, dense grain structure that cast hooks cannot match High tensile strength and impact resistance — essential for heavy-load and frequent-use operations Precise dimensions and uniform hardness — minimizes machining allowance and ensures consistent heat treatment results Mechanical properties significantly exceed cast hooks — safer and more durable under sustained heavy loading Double Hook vs. Single Hook Double hooks offer more balanced load distribution compared to single hooks, making them better suited for cranes with lifting capacities of 80 tons and above. While double hooks are somewhat more complex to manufacture and rig, their stability and safety advantages under heavy loads make them the standard choice for high-capacity cranes. For lighter-duty applications below 80t, single hooks are typically more practical and cost-effective. TUOKE Supply Range DIN-standard forged double hooks: full range available Smaller sizes: die-forged for precision and consistency Larger sizes: open-die forged for heavy-capacity applications Strength grades: M, P, S, T, and V per DIN 15400, with yield strengths from 235 MPa to 620 MPa.

Our Forging Process

Material Preparation

Certified alloy steel billets (34CrNiMo6, 42CrMo4, 34CrMo4, etc.) are selected and cut to precise weight. 100% incoming material inspection ensures traceability from the very first step.

Heating

Billets are heated in programmable gas-fired furnaces to exact forging temperature. Uniform heating prevents internal defects and ensures consistent grain flow.

Forging

Four hydraulic presses (up to 10,000T) shape the heated billets into hooks, wheels, or custom profiles. Over 200 forging die sets cover DIN standard and non-standard specifications from #2.5 to #250.

Rough Machining

CNC lathes and machining centers remove excess material and bring forgings to near-net shape, preparing surfaces for final precision work.

Heat Treatment

Controlled quenching and tempering achieve the required mechanical properties — hardness, tensile strength, and impact toughness — per international standards and customer specifications.

Finishing

Final machining achieves tight tolerances on critical dimensions. Surface quality is refined to meet strict specifications for assembly and performance.

Final Inspection

100% ultrasonic testing, magnetic particle inspection, dimensional verification, and hardness testing. Products ship with full EN 10204-3.1 certificates and classification society approval (LRS, DNV, ABS, BV).
