FAQs
Q
What if my project doesn't fit a standard boat size?
Then we build one that does. Every dredger we ship starts with your numbers—tonnage, depth, daily output. We customize from there and provide free design drawings so there are no surprises.
Q
How long will this boat be part of my fleet?
For many years to come. The hull is built for 8 to 15 years of steady work. The cutter and impeller—the parts that take the hardest hits—are good for 2 to 3 years. And we'll be there with replacements and advice as long as you own it.
Q
If something breaks, how fast can you help?
We don't leave you waiting. Our support team is available 24/7, and if we can't fix it remotely, we'll have someone on-site within 48 hours.
Q
Is this boat only for freshwater, or can it handle the sea?
It handles both. We use anti-corrosion materials throughout, so whether you're working in a lake or a shallow coastal zone, the boat performs reliably.
Q
Can the dredger be used for gold mining operations?
Yes. Our dredging vessels are fully compatible with gold mining machinery and can be configured for combined operations, making them suitable for both sand extraction and mineral recovery projects.
Q
What model should I choose for a large-scale industrial dredging project?
For large-scale industrial applications, we recommend models from DHCSD-300 to DHCSD-500, which offer water flow rates up to 4200 m³/hr and engine power up to 1500 kW. Our team can help you select the most cost-effective configuration based on your project scope and site conditions.
