Sky Crane Hook

　　Sky crane hooks, also known as overhead crane hooks, are a common name for industrial crane hooks. They are categorized by shape into single and double hooks, and by manufacturing method into forged and laminated hooks. Single hooks are simple and easy to use, and are often used for lifting capacities under 80 tons. Double hooks, due to their symmetrical load distribution, are often used for large-tonnage lifts. Laminated hooks, constructed from riveted steel plates, offer increased safety and are suitable for large-tonnage lifts.

　　Weihua Crane is China's largest industrial crane manufacturer. Its crane parts factory specializes in the production of various types of overhead crane hooks. Weihua Crane's overhead crane hooks feature a wide load range, sophisticated manufacturing processes, a comprehensive testing system, and reliable, durable quality. They can manufacture capacities ranging from 5 to 1000 tons and currently supply crane hooks to multiple crane brands.

　　Sky crane hooks manufactured by Weihua Crane offer the following advantages:

　　1. Material and Process Advantages

　　High-Strength Materials: Made from high-quality alloy steel (such as 20CrMnTi and 34CrMo), after heat treatment (quenching and tempering), they combine high hardness and toughness, achieving a tensile strength exceeding 700 MPa and providing wear and impact resistance.

　　Forging Process: Precision forging technology eliminates internal defects, resulting in continuous fiber flow and improved load-bearing capacity (e.g., a single hook can reach 300 tons).

　　Surface Treatment: Available in galvanized, spray-coated, or Dacromet-coated, their corrosion resistance meets ISO 9227 salt spray test standards (rust-free for over 500 hours).

　　2. Design and Safety Advantages

　　Structural Optimization: CAD/CAE simulation and dynamic load analysis ensure uniform stress distribution, with a safety factor of ≥4 times the rated load (according to the national standard GB/T 10051).

　　Anti-Unhooking Design: Standard safety tongue or locking device complies with ISO 4309 and OSHA fall protection standards. Modular Design: The quick-change hook system can be adapted to a variety of lifting devices (such as container hooks and swivel hooks), with a changeover time of less than 5 minutes.

　　3. Manufacturing and Testing Advantages

　　CNC Machining: CNC machine tools achieve a machining accuracy of 0.02mm, ensuring the matching tolerances between the hook, pulley, and bearing.

　　Non-destructive Testing: 100% magnetic particle inspection (MT) and ultrasonic testing (UT), with a crack detection sensitivity of 0.1mm.

　　Load Testing: Each batch undergoes a 125% overload test (e.g., a 100-ton hook tested at 125 tons without deformation).

　　4. Intelligence and Customization

　　Smart Hook: Integrated sensors monitor load, angle (with ±0.5% accuracy), and temperature in real time, with data wirelessly transmitted to the cloud to prevent overloading.

　　Rapid Customization: 3D printing prototypes for verification, reducing lead times to 7 days (for custom designs).

　　5. Certification and Environmental Protection

　　International Certifications: CE, ASME B30.10, and DNV GL certifications ensure global market access. Green Manufacturing: Scrap recycling rate >90%, waste heat from heat treatment is used in the preheating process, reducing energy consumption by 15%.

　　6. Cost-Effectiveness

　　Long-Life Design: Under normal operating conditions, service life exceeds 10 years (with proper maintenance), reducing replacement frequency.

　　Easy Maintenance: Standardized lubrication point design extends service intervals to 500 operating hours.

　　Weihua Heavy Machinery Co., Ltd. was founded in 1988. It is a large-scale equipment manufacturing enterprise mainly engaged in the development of bridge and gantry cranes, port machinery, electric hoists, reducers, bulk material conveying equipment and other products.

　　Weihua has won more than 500 honorary titles such as "National Technology Innovation Demonstration Enterprise", "National Torch Program Key High-tech Enterprise", "National Certified Enterprise Technology Center", "National Quality Benchmark", "National Green Factory", and "National Industrial Design Center".

　　Weihua has 10 series and more than 200 categories of crane production and manufacturing qualifications. The leading products are widely used in machinery, metallurgy, mining, electricity, railways, ports, petroleum, chemical and other industries, serving national key projects such as West-East Gas Transmission, South-to-North Water Diversion, Olympic Projects, Hangzhou Bay Cross-sea Bridge, and thousands of large enterprises such as China Coal, China Shenhua, Sinopec, China Petroleum, Baowu Steel, etc., and are exported to more than 170 countries and regions such as Thailand, Malaysia, and Australia.

　　Weihua has 33 national and provincial R&D platforms, and a scientific research team of more than 1,200 people led by Zhang Tiegang and Ma Yushan, academicians of the Chinese Academy of Engineering. It has successively undertaken 7 major national projects. The independently developed electrical anti-sway control technology is internationally leading. The 400-meter ultra-high winch has set a world record for the maximum lifting height. The AICrane intelligent control system has created a real crane robot. The new Chinese-style crane has redefined the concept of lifting and promoted the continuous iteration and update of China's lifting technology! Create Weihua international brand and promote the Chinese national industry. Henan Weihua is committed to becoming a global leading material handling equipment manufacturer and system solution provider, and contributing a world-class brand to the high-end equipment manufacturing industry.
