We manufacture sand dredgers, cutter suction dredgers, and core sand pumps. Our equipment is used in projects such as river channel cleaning, port maintenance, and land reclamation. We provide suitable equipment based on our customers’ specific needs.
1.Project Case: Sand Dredging Requirements of a Thai Customer
In June 2025, a Thai customer contacted us. They needed to dredge sand and fine gravel from a waterway.
They had several specific requirements:
– Working water depth: 15 to 20 meters.
– Sand dredging volume per hour: 100 cubic meters.
– Main material: Sand and fine gravel.
We understood that the customer needed to work stably for a long time in a waterway with specific water flow and environmental conditions. Therefore, we first inquired in detail about the specific conditions of the work site, such as the depth variations of the water, the hardness of the sand and gravel at the bottom, and how the dredged sand would be processed afterward. Understanding these factors allowed us to recommend the most suitable pump and vessel type.
2.Solution: How to Design This Equipment
After understanding the situation, we designed a 10-inch sand dredger solution for the customer. This solution focused on addressing several key issues:
Core Equipment Configuration:
2.1. Sand Pump:
We selected a centrifugal pump specifically designed for pumping sand and gravel. Its impeller and pump casing shape are optimized for smoother sand passage, preventing clogging, and are highly wear-resistant, allowing for longer working hours.
2.2. Hull Structure:
The entire equipment can be disassembled into multiple standard modules. This allows for transportation by container or truck, and quick assembly at the construction site, saving on transportation costs and installation time.
2.3. Power Options:
We offered both diesel engine and electric motor options. Customers can choose the appropriate option based on the availability of a convenient power source at the construction site, ensuring the equipment can operate anywhere.
To reassure the customer, we provided the following materials:
– Detailed technical parameter tables listing all performance data.
– On-site work videos and photos of other similar projects, allowing the customer to see the real-world results.
– A list of parts requiring regular replacement and maintenance instructions to help the customer plan ahead. The goal of this solution was to ensure the equipment could reliably extract 100 cubic meters of sand and gravel per hour in the designated waterway in Thailand.
3. Production Process: How We Deliver Reliable Equipment on Time
After the client confirmed the order, we began manufacturing at our factory. Every step, from steel procurement to final testing, had inspection standards. We completed all manufacturing and testing within 20 business days of receiving the deposit.
Our delivery process includes:
Factory testing: We simulated real working conditions at the factory, running the equipment continuously to check that all parts, including the pump, pipes, and engine, were functioning correctly.
Full photographic documentation: From parts processing to assembly and painting, and finally loading into containers, we took high-definition photos and videos. Clients could clearly understand the progress even without being on-site.
Complete documentation: We provided operating manuals, maintenance guides, and all technical documents with the equipment. We promised to provide guidance via phone or internet after the equipment arrived, and could also send technicians if necessary.
The client was satisfied with our fast delivery and transparent process.
4. Why Clients Choose Us
Many clients choose to cooperate with us mainly for these reasons:
4.1. Durable pumps:
Our pumps are used in highly abrasive sand dredging operations and have a long lifespan, reducing the hassle of frequent repairs and parts replacement.
4.2. Flexible equipment configuration:
No single piece of equipment can suit all construction sites. We can adjust the design based on the depth, width, and type of material in the client’s waterway, providing the most suitable vessel and pump.
4.3. Convenient transportation and installation:
The modular design of the equipment significantly reduces the cost and difficulty of international shipping, and assembly is quick at the construction site.
4.4. Extensive real-world project experience:
We have provided equipment for many domestic and international projects, including large-scale river and port engineering projects. We understand the problems that can arise in practical work.
4.5. Supportive after-sales service:
We provide a clear spare parts list and purchasing channels, ensuring quick solutions if equipment problems occur.
5. Results of the Thailand Project
The sand dredging vessel manufactured for the Thai client has been operating in their waterway for a long time. According to our subsequent information:
– The equipment consistently achieved the design requirement of 100 cubic meters of sand extraction per hour. – Because the pumps and key components were robust, there were no prolonged shutdowns due to equipment failure.
– After the waterway was cleared, ship navigation became safer and more convenient.
This case demonstrates that by clearly communicating beforehand and designing and manufacturing equipment that meets the specific requirements of the construction site, we can help our clients successfully complete their tasks.
