Introduction
The low headroom hook is optimized to address the large height footprint of conventional hook pulley blocks, with pulleys side-mounted or embedded inside the hook frame to shorten the vertical distance from pulley to hook body, achieving significant overall height reduction. The hook body is forged from quality alloy steel with high strength and toughness after heat treatment; pulleys are fitted with sealed rolling bearings for flexible and wear-resistant rotation. Retaining 360° rotation and spring safety latch, it reduces height without sacrificing safety and convenience, serving as an ideal load attachment for low-headroom electric hoists and single-girder cranes.
Application
Our Advantage
Side-mounted embedded pulley design reduces overall height by 25%~40% compared with conventional hooks, providing greater effective lifting height under the same workshop conditions without structural modifications.
Hook frame adopts integral welding or cast steel forming, offering compact structure, low center of gravity and high rigidity, reducing sway during lifting and significantly improving stability in space-constrained areas.
Thrust bearing between hook body and crossbeam allows 360° free rotation, automatically adapting to load direction during lifting, effectively preventing wire rope kinking and tangling with flexible operation.
Standard spring-loaded anti-derailment latch with moderate locking force and smooth opening/closing automatically closes after sling insertion, completely preventing accidental wire rope or sling detachment during lifting.
Pulleys made of cast iron/cast steel with sealed rolling bearings offer low rotational resistance and good wear resistance, effectively reducing wire rope wear and extending overall service life.
