Technical Highlights
Pin-Connect Architecture: The top mounting hole is machined to tight tolerances, designed to accept a load pin. This allows for rapid integration into spreader bars or clevis-style mounting points, offering a lower profile than traditional threaded shank assemblies.
Split-Load Geometry: The "double-hook" shape naturally forces lifting slings apart. This separation significantly improves the center-of-gravity stability when handling wide loads and prevents damage caused by slings crushing against each other.
Forged Grain Structure: We utilize a closed-die forging process that aligns the steel grain flow with the contour of the hook. This results in superior tensile strength and impact resistance compared to cast or cut-plate alternatives.
Dual Safety Keepers: Safety is doubled with spring-loaded latches on both hook throats, ensuring that rigging hardware remains captive even if the load line becomes slack during positioning.
Optimized Saddle Profile: The curved bearing surface of the hook is engineered to maximize the contact area with wire ropes or synthetic web slings, reducing localized stress points.
Fabrication & Material Classes
We do not just sell standard parts; we engineer connection points to fit your specific machinery. Our manufacturing process adheres to strict lifting grades (e.g., DIN 15402 standards).
Tailored Specifications:
Steel Grades: Available in Strength Classes P, S, T, and V to match your required safety factors.
Bore Dimensions: The eye diameter and bushing thickness can be machined to perfectly match your existing load pin size.
Protective Finishes: Options include sandblasting, anti-rust oiling, or marine-grade painting.
Primary Use Cases
Spreader Beams: Direct attachment to the central lug of lifting beams.
Low-Headroom Blocks: Ideal for compact crane blocks where vertical space is limited.
Project Cargo: Handling oversized equipment requiring multi-leg sling setups.
