Gantry Crane Hook

　　Gantry crane hook is a key load-bearing component, and its design and operational characteristics directly impact the safety and efficiency of lifting operations. Gantry crane hooks manufactured by Weihua Crane's parts factory feature the following:

　　1. High Strength and Durability

　　Material Selection: Typically forged from high-quality alloy steel (such as 20CrMnTi), they undergo heat treatment (quenching and tempering) to enhance hardness and toughness. Load capacities range from one ton to several hundred tons.

　　Safety Factor: The rated load is generally at least twice the rated lifting capacity (for example, GB/T10051 requires a breaking load ≥ 4 times the rated load).

　　2. Standardized Design

　　Type Classification:

　　Single Hook: For light to medium loads (≤80 tons), with a simple structure and excellent visibility.

　　Double Hook: For heavy loads (>80 tons), with symmetrical load distribution.

　　Claw Hook: With side plates to prevent the sling from slipping, commonly used on metallurgical cranes.

　　Compliance: Conforms to international/national standards such as ISO, DIN, and GB (e.g., GB/T10051.1-2010).

　　3. Safety Devices

　　Anti-Unhooking Design:

　　Spring Lock: Automatically closes to prevent the sling from unhooking (e.g., swivel safety hook).

　　Baffle/Catch: Manually locked, suitable for large-tonnage hooks.

　　Overload Protection: Some hooks have integrated sensors for real-time load monitoring (e.g., electronic weighing hooks).

　　4. Flexibility and Adaptability

　　Rotation: Some hooks are equipped with bearings (e.g., 360° swivel hooks) for precise positioning, making them particularly suitable for container loading and unloading.

　　Modular Accessories: Optional accessories such as electromagnetic chucks and C-hooks can be added to accommodate specialized materials such as steel and scrap metal.

　　5. Convenient Maintenance and Inspection

　　Inspection Points:

　　Wear: Hooks with >15% deformation of the opening or >10° twisting must be scrapped.

　　Cracks: Regular inspection with magnetic particle inspection (recommended every 6 months).

　　Lubrication Design: Grease holes are provided at the shaft pin to reduce wear.

　　6. Environmental Adaptability

　　Corrosion Protection: Galvanized, plastic-sprayed, or stainless steel (for chemical and port applications).

　　High-Temperature Protection: Heat shield installed (metallurgical hooks withstand temperatures exceeding 500°C).

　　7. Ergonomic Optimization

　　Weight Balance: Large-tonnage hooks are equipped with a balanced pulley system to reduce vibration.

　　Clear Marking: Permanently mark information such as the rated load and production number.

　　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.
