Our Heavy-Duty Marine Crane hook is precision-engineered for the rigorous demands of shipyard lifting operations. Built to handle massive loads, resist harsh marine environments, and ensure maximum safety, this hook is the critical link between your crane and cargo—from engine blocks and steel plates to ship sections and dry-dock equipment.
1. Kekuatan Tanpa Kompromi & Daya tahan
Bahan: Ditempa dari baja paduan tinggi (Grade 100/Alloy E), heat-treated for exceptional toughness.
Kapasitas muatan: Rated for SWL (Safe Working Loads) from 5 ke 500+ ton. Custom designs available.
Resistensi korosi: Triple-protected with hot-dip galvanizing, marine-grade epoxy coating, or stainless steel variants (316L).
2. Sistem Keamanan yang Ditingkatkan
Kait pengaman: Spring-loaded, panduan, or semi-automatic latches prevent accidental disengagement.
Perlindungan Kelebihan Beban: Optional integrated load cells for real-time monitoring (API-compliant).
Fail-Safe Design: Fatigue-resistant construction per FEM 9.511 and ISO 4301/EN 13889 standar.
3. Optimized for Marine Workflows
360° Rotation: Swivel hooks eliminate wire rope twisting during precise positioning.
Low-Profile Design: Clears confined shipboard spaces, decks, and dry-dock structures.
Shock Absorption: Resilient thrust bearings reduce dynamic stress during heavy lifts.
4. Smart Inspection & Pemeliharaan
Wear Indicators: Visual markers highlight critical wear zones (tenggorokan, tip).
Easy-Grease Fittings: Lubrication ports extend bearing/bolt life.
Keterlacakan: Laser-etched ID with SWL, nomor seri, and certification details.
