Crane hooks are important parts of overhead cranes, gantry cranes, electric hoists and other lifting equipment. The quality of crane hooks plays a vital role in the safe operation of cranes. During the production and operation process, crane hooks manufactured by large brand crane manufacturers should be selected to ensure the safe operation of cranes.
Weihua Crane is an important crane brand manufacturer in the world. The crane hooks manufactured by Weihua Crane have the characteristics of high strength, strong durability, wide adaptability, long service life, easy maintenance, etc., and can be customized according to the actual needs of customers.

1. High strength and durability
·Forged with high-quality alloy steel (such as 20CrMo, 34CrMo, etc.), after heat treatment (quenching + tempering), the tensile strength can reach more than 700MPa, wear and impact resistance, and the service life is increased by 30%-50%.
·Surface galvanizing or spray anti-corrosion treatment, suitable for humid and corrosive environments (such as ports and chemical fields).
2. Safety redundancy design
·Standard anti-unhooking devices (such as spring locks, flap locks), in line with international safety standards such as ISO8305 and DIN15400, prevent accidental slippage of rigging during lifting.
·Safety factor ≥ 4:1 (breaking strength more than 4 times the rated load), certified by third-party organizations (such as TUV, CE).
3. Modular and multi-functional adaptation
·Quick-change hook design (such as CROSBY's Shur-Loc system), different types of slings (such as container hooks, rotating hooks) can be replaced within 3 seconds.
·The tonnage covers 0.5-1000 tons, supports single hook, double hook, combined hook and other configurations, and is suitable for various equipment such as bridge cranes, tower cranes, and truck cranes.
4. Ergonomic optimization
·Low deadweight design (15%-20% lighter than traditional hooks) reduces equipment energy consumption; streamlined structure reduces air resistance during lifting.
·360° rotating bearing option to achieve torque-free lifting, especially suitable for long materials such as wind turbine blades and pipes.
5. Intelligent monitoring function (optional)
·Integrated sensors monitor load, angle, and wear data in real time, and transmit them to the cloud through IoT modules to warn of overload or fatigue status (such as Konecranes' TRUCONNECT system).
6. Convenient maintenance
·The self-lubricating bearing design that does not require lubrication reduces maintenance frequency; replaceable bushings are used in wear parts, reducing maintenance costs by 40%.
