Overview
The hook of a bridge crane is one of the core components of a lifting machine. It is usually made of high-quality alloy steel forging or riveted with steel plates, and has the characteristics of high strength, wear resistance and impact resistance. The hook is mainly composed of a hook body, a hook neck, a hook handle and other parts, and is connected to the lifting mechanism through a pulley block to achieve the lifting and handling of heavy objects. According to the manufacturing process, the hook can be divided into a forged hook (strong integrity, suitable for large tonnage) and a laminated hook (riveted by multiple layers of steel plates, which can be partially replaced when damaged).

The safety design of the bridge crane hook includes anti-unhooking devices (such as spring locks), overload protection, and regular inspections (such as opening deformation inspection and crack detection). Its rated load must strictly match the working level of the crane, and overloading is prohibited. Daily maintenance requires checking wear, deformation and lubrication to ensure compliance with relevant industry standards.

The flexibility and durability of the bridge crane hook make it widely used in factories, warehouses, ports and other scenes, and it is an indispensable key component in material lifting operations.

The bridge crane hooks produced and supplied by Weihua Crane have the advantages of high strength, good durability, safety and reliability, good adaptability, and easy maintenance. They can also be customized according to customer needs. We sincerely welcome customers to contact us quickly.
Features
The bridge crane hook combines material science, structural optimization and intelligent technology to demonstrate its core advantages of efficiency, safety and durability in factories, warehouses, ports and other scenarios. It is a key component of modern material handling systems.
High strength and reliability
High-quality materials: forged or die-forged with high-strength alloy steel (such as 20CrMnTi), tensile strength ≥800MPa, safety factor ≥4 times.
Precision manufacturing: The hook body is heat-treated and tested for flaw detection to ensure no internal defects, and the fatigue life is more than 100,000 times (GB/T 10051 standard).
Wide load range: covers different tonnage requirements from 0.5 to 500 tons, suitable for light material handling to heavy industrial lifting.
Safety protection design
Anti-unhooking device: standard mechanical safety tongue or spring lock to prevent accidental detachment of the sling.
Overload protection: Some models integrate electronic weighing sensors, automatically alarm and limit lifting when overloaded.
Wear-resistant structure: The hook mouth and stress-bearing parts are quenched and hardened, and the wear resistance is improved by more than 50%.
Efficient operation performance
Low resistance rotation: Precision bearings achieve 360° smooth rotation, with rotation resistance ≤1.5% rated load.
Quick replacement design: Modular beam connection supports quick switching between hooks and slings (such as C-hook, clamp).
Human-machine optimization: Complies with ISO 12480-1 standard, flexible operation, and reduces driver fatigue.
Environmental adaptability
Anti-corrosion type: Surface galvanizing or spraying corrosion-resistant coating, suitable for harsh environments such as humidity and chemical industry (C4 grade anti-corrosion).
High temperature type: Special alloy steel can work for a long time below 200℃ and withstand high temperature of 400℃ for a short time.
Dustproof seal: IP54 protection level of rotating parts, effectively blocking dust intrusion.
