Heavy Crane Hook

　　Weihua Crane is one of China's leading crane manufacturers. Its heavy crane hooks are known for their high safety, excellent load-bearing capacity and long life, and are widely used in metallurgy, ports, energy, heavy machinery and other fields.

　　Weihua Crane's heavy crane hooks have become a reliable choice in the field of large-scale industrial lifting due to their material technology and intelligent design, especially suitable for scenes with extremely high requirements for safety and stability.

　　1. Product Positioning

　　· Applicable scenarios: heavy industry, large-tonnage lifting (such as steel smelting, wind power equipment, shipbuilding, etc.).

　　· Load range: Covers heavy-duty lifting needs of 5 tons to 500 tons and above, and supports customized super-large hooks.

　　2. Core technology advantages

　　(1) High-strength materials and processes

　　· Material: Made of high-quality alloy steel (such as 34Cr2Ni2Mo), forged + heat treated (tempered, flaw detection), with a tensile strength of more than 800MPa, impact resistant and fatigue resistant. Surface treatment: galvanized, Dacromet coating or plastic spraying, suitable for high temperature, humid and corrosive environments (such as ports and chemical plants).

　　(2) Safety design

　　Anti-unhooking structure: standard heavy-duty safety tongue, in line with ISO 24100 and GB/T 10051 standards, and passed 125% overload test.

　　Overload protection: optional intelligent sensor hook (real-time monitoring of load and angle, wireless data transmission to the control system).

　　(3) Modularity and compatibility

　　Quick change system: standardized DIN 15400 or ANSI B30.10 interface, suitable for Weihua cranes and other brands of equipment.

　　Rotation function: some models support 360° stepless rotation to avoid wire rope twisting (such as for wind turbine tower hoisting).

　　3. Product Series

　　Types, Features, and Typical Applications

　　Single hook type offers a simple structure and is suitable for lifting ladles in centralized steel mills and heavy machinery.

　　Double hook type offers balanced load distribution and is suitable for lifting large modular building components.

　　Rotating hook with bearings prevents entanglement in wind turbine blades and port containers.

　　Electric hook assembly with integrated motor drive enables precise positioning in automated production lines and precision equipment installation.

　　4. Quality Assurance

　　· Certifications: CE, ISO 9001, and China Special Equipment Manufacturing License (TSG).

　　· Inspection Process: Each batch of hooks undergoes magnetic particle testing (MT) and ultrasonic testing (UT) to ensure the absence of internal defects.

　　5. Service Support

　　· Customized Solutions: Customized hooks can be designed to meet specific application requirements (e.g., high-temperature resistance, anti-magnetization).

　　· Global After-Sales Service: Technical training, regular maintenance, and emergency spare parts supply are provided.

　　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!
