HID's new generation 'amphibious dredger' praised by frontline project teams

HID's new generation 'amphibious dredger' praised by frontline project teams.

The amphibious dredger fleet independently developed and manufactured by HID Shipyard has become the most eye-catching 'star equipment' on the construction site. Faced with complex and ever-changing lake shore terrain and strict environmental construction timelines, HID's amphibious dredgers, with their 'non-picky' work adaptability and 'non-stop' operational efficiency, have delivered a perfect performance.

In traditional dredging projects, nearshore areas with water less than 1.5 metres deep and marshlands with poor mud-bearing capacity have always been 'no-go zones' for large cutter suction dredgers and 'blind spots' for ordinary long-arm excavators. During the early stages of the Poyang Lake governance project, the construction team encountered several kilometres of high-water-content muddy tidal flats, with conventional vessels facing a very high risk of grounding.

We faced a dilemma: either wait for the water level to rise and delay the project, or take risks that could lead to equipment getting stuck,' recalled the project's chief engineer on site. 'It wasn't until HID's amphibious dredger arrived that the problem was solved.'

Equipped with a hydraulic lift leg system and large buoyancy sealed hull, the HID amphibious dredger can float in deep water and, thanks to its unique 'walking-type driving mechanism', achieve 'soft landing' and 'slow crawling' on extremely low-bearing tidal flats and marshlands. On site, you can see this steel giant slowly moving from the water to the shore, its tracks firmly gripping the underwater hard bottom, the cutter head easily breaking up compacted sandy soil, with the whole process flowing smoothly to achieve genuine 'floating on water, walking on land, crawling on tidal flats'.

With the country's increasing investment in small and medium river management, wetland restoration, and urban sponge city construction, HID's amphibious dredger is gradually becoming the equipment of choice in the domestic eco-dredging market, thanks to its three core advantages: high mobility, low environmental impact, and strong adaptability.
