Obsah Zobraziť

Our Heavy-Duty Marine Žeriavový hák 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.

Key Features & Benefits

1. Uncompromising Strength & Durability
- Materiál: Forged from high-tensile alloy steel (Grade 100/Alloy E), heat-treated for exceptional toughness.
- Kapacita zaťaženia: Rated for SWL (Safe Working Loads) from 5 to 500+ ton. Custom designs available.
- Corrosion Resistance: Triple-protected with hot-dip galvanizing, marine-grade epoxy coating, or stainless steel variants (316L).
2. Enhanced Safety Systems
- Safety Latch: 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 štandardy.
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 & Maintenance
- Wear Indicators: Visual markers highlight critical wear zones (throat, tip).
- Easy-Grease Fittings: Lubrication ports extend bearing/bolt life.
- Traceability: Laser-etched ID with SWL, serial number, and certification details.
