A batch of intelligent dredging grabs independently developed by ENJUE has been shipped from China to the ports of Paranaguá and Itajai, Brazil, providing core equipment for local deepwater channel dredging projects. With their high precision, adaptability, and environmentally friendly features, these grabs are becoming a key tool in addressing the siltation problem at Brazilian ports, marking another breakthrough for Chinese dredging technology in the South American market.
The dredging grab provided by ENJUE is specifically designed for deepwater, hard-bottomed mud, and complex environments, offering three core advantages:
High-precision operation: The dredging grab's internal pulleys utilize multi-pass sealing technology, ensuring zero penetration in seawater tens of meters deep. Combined with an RTK-GPS positioning system, the dredging depth error is controlled within 10 centimeters, meeting Brazil's stringent acceptance standards.
High adaptability: The dredging grab has a lifting capacity ranging from 6 tons to 200 tons and is compatible with single-, double-, and four-rope cranes. It can handle a wide range of substrates, from soft mud to iron plate sand and blasted reefs. During emergency dredging at the Port of Itajai, the grab successfully cleared 14 meters of silt and concrete blocks, restoring the port's navigability.
The Brazilian market's recognition of Chinese dredging technology stems from its stringent environmental regulations and high standards. Brazil is rich in wildlife, and construction operations must strictly adhere to avoidance principles.
For example, in the Paranaguá Port Dolphin Sanctuary, dredging grab operations require a speed reduction if dolphins appear within 500 meters and a complete cessation within 300 meters.

The ENJUE dredging grab's precise control system balances construction with ecological protection.
Brazilian engineer Marcelo noted, "Chinese dredging vessels are highly automated and have large tank capacities. We have learned advanced technology through our cooperation."
The export of the ENJUE dredging grab not only fills a technological gap in Brazilian equipment but also promotes the evolution of China-Brazil cooperation from "project collaboration" to technological symbiosis.
The export of this dredging grab is not only a microcosm of China's equipment "going global," but also a model for China-Pakistan technical cooperation under the Belt and Road Initiative. From addressing waterway siltation to protecting marine ecosystems, ENJUE is leveraging innovation to provide Chinese solutions for global deepwater dredging projects.
