The lifting crane hook is the core load-bearing component of the crane system and is directly related to the safety and efficiency of hoisting operations. This series of lifting crane hooks adopt high-strength materials and intelligent design, and are suitable for heavy equipment hoisting, material handling and precision installation operations in construction, porty, energy, manufacturing and other fields. The products have passed strict quality certification and take high safety factor, long life cycle and intelligent protection functions as core competitiveness to help customers achieve safe and efficient lifting goals.

Core design features of lifting crane hook

High-strength materials and craftsmanship

• Tworzywo: The main body of the lifting crane hook is forged from 42CrMo/34CrNiMo6 alloy steel. After quenching + tempering heat treatment process, the tensile strength is ≥1000MPa, the hardness reaches HRC 45-50, and it is impact-resistant and deformation-resistant.
• Anti-corrosion treatment: The surface is hot-dip galvanized or Dacromet coated, with salt spray corrosion resistance time of ≥1000 hours, suitable for high-humidity and high-salt environments such as ports and seas.

Intelligent security protection system

• Overload monitoring (fakultatywny): Built-in wireless sensor monitors the Haczyk dźwigu load in real time. When overloaded, it automatically triggers an audible and visual alarm and uploads data to the control terminal.
• Anti-decoupling double insurance: Equipped with spring lock tongue + mechanical buckle double locking device, complying with ISO 2415 and ASME B30.10 safety standards.
• 360° rotating bearing: The lifting crane hook adopts a sealed roller bearing, which supports the free rotation of the hook, reduces the risk of wire rope entanglement, and extends the life of the rope.

Modularity and ease of maintenance

• Quick-release structure: The lifting crane hook and boom are connected using a standardized pin interface, which supports quick replacement and reduces equipment downtime.
• Wear visualization: Laser markings are set on key parts such as hook tips and bearings to facilitate regular detection of wear and achieve preventive maintenance.

Basic parameters of lifting crane hook

Notatka:

• Współczynnik bezpieczeństwa: defined as the ratio of the minimum breaking strength to the rated load to ensure safety under extreme working conditions.
• Rotating bearing: fully enclosed design, IP67 protection grade, dustproof and waterproof, lubrication-free maintenance.
• Extended functions: Optional load recorder, remote monitoring module or anti-collision sensor.

Quality assurance and after-sales service

• Strict testing: Each lifting crane hook has passed 100% magnetic particle inspection (crack detection) and static load/dynamic load test.
• Warranty commitment: Provide 2-year free warranty and lifetime maintenance support.
• Global service: 48-hour emergency response, providing on-site maintenance, spare parts replacement and technical training.
• Customized services: Support non-standard designs (such as explosion-proof and ultra-low temperature hooks) to meet the needs of special working conditions.

Lifting crane hook selection suggestions

• Normal working conditions: Choose standard safety factor (4:1) galvanized hooks, such as construction sites and logistics warehouses.
• Extreme environment: Priority is given to high anti-corrosion coatings or ultra-low temperature materials, such as offshore operations and polar scientific expeditions.
• High frequency and heavy load: need to match high safety factor (≥5:1) + intelligent monitoring module, such as steel plants and heavy manufacturing.
