Full-hydraulic Dredger

Hydraulic dredgers, especially hydraulic cutter suction dredgers, are the core equipment in modern waterway engineering. They operate through a hydraulic system to drive key components such as the cutter, mud pump, and positioning piles, enabling continuous integrated operations of excavation, suction, and transportation. This design enables it to perform exceptionally well in river management, port construction, land reclamation and other projects, making it the preferred equipment for enhancing construction efficiency and environmental standards.

01 Cutter Head
This cutter head disperses the sediment at the bottom of the water and discharges it into the suction pipe opening, facilitating maintenance (with a replaceable tooth system). It is made of thickened high-manganese alloy copper, which has high toughness and hardness, helping to increase the digging efficiency.

02 Dredging Pump
This pump sucks up the materials that need to be cleared from the bottom of the water and discharges them to the designated location. It uses a pump from the industrial factory in Shijiazhuang, Hebei Province, which has a long service life.

03 Marine Engine
The marine engine is equipped with a domestically renowned brand engine, which is sturdy, durable and has a low failure rate.

Efficient and precise, with flexible control: The full hydraulic system supports continuous speed adjustment and electro-hydraulic proportional control, enabling precise adjustment of the drill bit speed and the flow rate of the mud pump. It can easily handle various geological conditions ranging from soft mud to hard rock strata, with high operational accuracy.
Energy-saving and environmentally friendly, with reliable operation: The hydraulic system distributes power as needed, reducing energy consumption by more than 20% compared to traditional mechanical transmission. The closed oil circuit and pipeline mud transportation effectively prevent oil leakage and sediment dispersion, meeting the requirements of green construction.
High adaptability and easy deployment: Adopting a modular assembly design, the hull can be disassembled and transported by land, enabling rapid deployment in areas without connected waterways. The shallow draft and positioning pile system make it suitable for various complex conditions such as inland rivers, lakes, reservoirs, ports, and coastal areas.
Intelligent integration and easy maintenance: Equipped with a PLC intelligent operation platform, it can achieve one-click dredging and remote monitoring. Key components such as the cutting tool and the mud pump are made of high-chromium wear-resistant alloy, which ensures long service life and low maintenance costs.

Water Conservancy and Environmental Protection Dredging: Used for removing sediment from rivers, lakes, and reservoirs to restore capacity and improve water quality; implementing ecological treatment of urban blackwater bodies.
Port and Waterway Engineering: Conducting dredging and maintenance of waterways, excavation of harbor basins, and cleaning of base channels, as well as using dredged sediment for land reclamation.
Marine and Resource Development: Utilized for compliant sand extraction at sea, collection and cleaning of underwater minerals such as gold, and environmental mechanical reef removal in ecologically sensitive areas.
Industrial and Emergency Rescue: Applicable to industrial sedimentation tank cleaning and emergency dredging for flood control, etc.
