Our flagship machines are engineered for the unique hydrological conditions of Switzerland's rivers, alpine lakes, and industrial water systems.
Weifang Duohui Intelligent Manufacturing Technology Co., Ltd. has been deeply engaged in the field of dredging and cleaning equipment. With its strong R&D capabilities as the core, it focuses on the research, manufacturing, and full-chain sales of high-quality dredging equipment. By leveraging a mature technical system and intelligent manufacturing capabilities, it has developed engineering equipment suitable for various scenarios.
The product is widely used in various water conservancy projects such as river dredging, waterway excavation, port construction, and reservoir management. The main business includes a full range of core equipment: dredging vessels, amphibious multi-functional dredging vessels, environmental clean-up vessels, high-concentration clean-up vessels, grass-cutting vessels, soft foundation spiral multi-functional platforms, as well as salt mine mining vessels, large tin mining vessels, powerful mixing and solidification machines, mud solidification equipment, and gold selection equipment for sand mines. With technology, it empowers construction projects and fully meets the high-standard operation requirements in multiple fields such as water conservancy, mining, and environmental protection.
Switzerland's unique geography — featuring over 1,500 lakes, the Rhine, Rhône, Aare, and dozens of alpine tributaries — creates a constant and growing demand for professional river dredging and waterway maintenance equipment.
Switzerland's alpine rivers carry significant sediment loads from glacial melt and seasonal snowmelt. Dredging operations on rivers like the Rhine and Rhône are critical for flood prevention, navigation safety, and maintaining ecological balance. Specialised dredging machines capable of operating in fast-flowing, shallow alpine conditions are in high demand from Swiss cantonal authorities and federal waterway agencies.
Switzerland's inland ports — particularly along the Rhine corridor connecting Basel to the North Sea — require regular dredging to maintain navigable depths for commercial shipping. The Port of Basel, Switzerland's only seaport, processes millions of tonnes of goods annually. Continuous dredging and sediment management are essential for sustaining freight operations and supporting Switzerland's export-driven economy.
Swiss environmental regulations are among the strictest in Europe. The Swiss Federal Office for the Environment (BAFU/OFEV) funds numerous lake and river restoration programmes. Dredging machines used in Switzerland must meet rigorous emissions standards, minimise turbidity, and support ecological restoration goals — including sediment removal from contaminated industrial sites and the rehabilitation of wetland habitats.
Switzerland's drinking water supply relies heavily on pristine alpine reservoirs and lake systems. Regular sediment dredging is essential to maintain water quality, storage capacity, and dam safety. Projects on Lake Geneva, Lake Zurich, and Lake Constance require precision dredging equipment that can operate without disrupting water treatment infrastructure or sensitive aquatic ecosystems.
Switzerland generates approximately 60% of its electricity from hydropower. Sedimentation in reservoirs and intake channels reduces turbine efficiency and power generation capacity. Dredging machines are deployed at facilities across the Swiss Alps to remove accumulated sediment from hydropower reservoirs, ensuring optimal energy output and extending the operational lifespan of these critical national infrastructure assets.
Swiss cities including Zurich, Geneva, Bern, and Lucerne feature extensive urban canal networks and lakefront waterfronts that require regular maintenance. Municipal dredging contracts cover canal cleaning, debris removal, and the management of urban runoff sediment. Compact, low-noise, and low-emission dredging vessels are particularly suited to these sensitive urban environments.
The dredging equipment market in Switzerland is evolving rapidly, driven by technological innovation, environmental legislation, and infrastructure investment programmes.
The integration of artificial intelligence and machine learning into dredging operations is transforming the industry. Autonomous dredging vessels equipped with AI navigation, real-time sediment analysis, and adaptive dredging depth control are being trialled on Swiss lakes and rivers. These systems reduce labour costs, improve precision, and enable 24/7 operations in remote alpine locations.
Switzerland's commitment to net-zero emissions by 2050 is driving demand for electric and hybrid-powered dredging equipment. Battery-electric dredging vessels produce zero direct emissions, significantly reducing environmental impact on sensitive Swiss water bodies. Several Swiss cantonal governments are now requiring electric or hybrid dredging solutions for projects in protected nature reserves and drinking water catchment areas.
Modern dredging machines deployed in Switzerland increasingly feature IoT sensors and remote monitoring platforms. Operators can track dredging performance, equipment health, fuel consumption, and sediment output in real time from a central control room. This technology is particularly valuable for managing dredging operations across multiple sites simultaneously — a common requirement for Swiss water management authorities overseeing large river systems.
There is growing emphasis on circular economy principles in Swiss dredging projects. Dredged sediment is increasingly being processed and reused as construction material, agricultural soil amendment, or for land reclamation — rather than simply disposed of. Advanced dredging equipment with integrated sediment classification and processing capabilities is becoming standard in Swiss public procurement specifications.
Swiss engineering firms are adopting Building Information Modelling (BIM) and digital twin technology for waterway infrastructure projects. Dredging equipment manufacturers that can provide digital integration capabilities — including real-time data feeds compatible with BIM platforms — are gaining competitive advantage in the Swiss market. This trend is expected to accelerate as Swiss federal infrastructure programmes mandate BIM compliance.
Switzerland's Waters Protection Act (GSchG) and the EU Water Framework Directive (which Switzerland aligns with through bilateral agreements) are driving increasingly stringent requirements for dredging operations. Equipment must minimise turbidity, protect aquatic biodiversity, and comply with strict noise limits. Manufacturers offering environmentally certified dredging solutions have a significant market advantage in Switzerland's highly regulated operating environment.
