Introduction
The European-style crane hook adopts advanced European lifting design concepts, using large-diameter pulley blocks to reduce wire rope bending stress, extending wire rope life by over 30% compared with conventional hooks. The hook frame adopts precision cast steel or welded box-type structure with compact design and high rigidity, effectively reducing overall headroom. The hook body is forged from high-strength alloy steel, heat-treated and magnetic particle inspected, with safety factor over 5 times. Pulleys are fitted with double-row sealed rolling bearings for flexible, wear-resistant and maintenance-free rotation. Functional modules such as manual rotation, electric rotation, insulation and high-temperature resistance can be configured on demand; modular design facilitates maintenance and replacement, serving as an ideal load attachment for modern intelligent overhead cranes.
Application
Our Advantage
Pulley diameter is over 20% larger than GB-standard type, greatly reducing wire rope bending stress and wear, extending wire rope service life by over 30% and significantly lowering replacement costs and downtime.
Hook frame adopts European box-type compact design, with overall height 15%~25% lower than conventional hooks, providing greater effective lifting height under the same workshop conditions, fully utilizing space and reducing construction costs.
Hook body is integrally forged from high-strength alloy steel, normalized and tempered, with high tensile strength and good toughness, safety factor ≥5 times, with 100% magnetic particle inspection ensuring no internal defects for safe heavy-duty operation.
Pulleys adopt double-row sealed rolling bearings with low rotational resistance, self-lubrication and maintenance-free design, maintaining flexible rotation after long-term use, effectively reducing hoisting motor power loss and improving operating efficiency.
Functional modules such as electric rotation, insulation, high-temperature resistance and weighing display can be configured according to working conditions; each module is independently designed for easy assembly and disassembly, meeting both standard lifting needs and special working condition customization.
