Hook: Core load-bearing component, high-strength alloy steel.

Hook Crossbeam: Balanced load distribution, adaptable to double or multi-rope systems.

Hook Nut: Secure fastening with reliable anti-loosening.

Pull Plate: Support and force transmission.

Sheave / Sheave Axle: Directional change and friction reduction.

Hot-rolled sheave manufactured according to WJ China Industry Standards.

Function: Redirecting the wire rope and reducing wear.

Features: Cost-effective, mass-produced, suitable for medium and light-duty cranes, with hot-rolled surfaces and machined rope grooves.

A sheave manufactured using the ring forging process.

Function: Redirecting the wire rope and reducing wear. Higher Strength.

Features: Continuous fiber structure, excellent fatigue resistance, suitable for high-frequency and heavy-duty port equipment.

A sheave forged from a single piece of steel, non-welded.

Function: Redirecting the wire rope and reducing wear; the highest option.

Features: No weld defects, highest strength, commonly used in ultra-large-scale cranes.

A wide-groove sheave specifically designed for bulk ship unloaders

Function: Accommodating thick wire ropes or grab bucket ropes.

Features: Wider rope grooves to prevent multi-layer wrapping or groove skipping, equipped with a wear-resistant coating.

A sheave structure featuring two side plates/webs

Function: Enhancing rigidity and reducing deformation.

Features: Higher strength than single-web designs, commonly used in heavy-duty or high-speed applications.
