A: It excels at handling dry bulk and irregular materials—like sand, coal, grain, slag, and scrap—and is specifically engineered for efficient loading and unloading using EOT (Overhead Traveling) bridge cranes.
A: It’s built with a shortened through‑beam for high strength and light weight; a multi‑layer seal and a mere 0.3 mm gap between knife‑edge plates ensure good sealing; made from wear-resistant steel and sturdy components, it’s dirt‑proof, waterproof, distortion‑resistant and even suitable for underwater operations.
A: Sinoko offers models from 0.5 m³ (DYZ3, 1.5 t self‑weight, for 3.2 t cranes, 11 kW motor, 180 bar, ~10 s close time) up to 20 m³ (DYZ30, 11 t, for 30 t cranes, 45 kW, 200 bar, ~28 s).
A: Yes—its sealing craftsmanship, high‑quality bearing components, and wear‑resistant construction allow reliable operation even when submerged or exposed to dirt and moisture.
A: Hydraulic grabs use cylinders for smoother, faster, and more precise opening and closing; they often include optional rotation. Mechanical versions rely on ropes and pulleys—simpler and cheaper, but less precise and slower, making hydraulic versions preferable for repetitive heavy‑duty tasks.
A: They are widely deployed in ports, steel mills, waste and recycling centers, and other industrial settings—especially where irregular, bulky, or abrasive materials such as scrap, slag, demolition debris, or steel residues need precise and powerful handling.
