Our Heavy-Duty Marine Cangkuk kren 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. Uncompromising Strength & Ketahanan
Bahan: Dipalsukan dari keluli aloi tegangan tinggi (Grade 100/Alloy E), heat-treated for exceptional toughness.
Kapasiti beban: Rated for SWL (Safe Working Loads) from 5 ke 500+ tan. Custom designs available.
Rintangan kakisan: Triple-protected with hot-dip galvanizing, marine-grade epoxy coating, or stainless steel variants (316L.).
2. Sistem keselamatan yang dipertingkatkan
Selak keselamatan: Spring-loaded, manual, or semi-automatic latches prevent accidental disengagement.
Overload Protection: 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 piawaian.
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 & Penyelenggaraan
Wear Indicators: Visual markers highlight critical wear zones (throat, Petua).
Easy-Grease Fittings: Lubrication ports extend bearing/bolt life.
Kebolehkesanan: Laser-etched ID with SWL, nombor siri, and certification details.
