Introduction
The European-style hook adopts advanced European 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 sheet-metal structure with smooth lines and compact design, 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 rotation and durability. Integrating 360° rotation thrust bearing and spring safety latch, it balances operational convenience and safety, serving as an ideal matching component for modern intelligent lifting equipment.
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.
Hook frame adopts European compact design, with overall height 15%~25% lower than conventional hooks, providing greater effective lifting height under the same workshop conditions and fully utilizing workshop space.
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.
Pulleys adopt double-row sealed rolling bearings with low rotational resistance, self-lubrication and maintenance-free design, maintaining flexible rotation after long-term use and effectively reducing hoisting motor power loss.
Hook frame adopts precision cast steel or CNC bent sheet-metal forming, surface is shot-blasted and powder-coated with uniform color and strong adhesion, offering modern aesthetic appearance suitable for high-end intelligent equipment.
