The SJT850 Vertical Hydraulic Dual Cutter Suction Machine is a high-efficiency underwater soil excavation device designed for clearing and excavating hard soil layers, clay layers, and gravel layers. Equipped with an independent underwater hydraulic power unit, this machine delivers powerful cutter suction capabilities, enabling fast and efficient soil excavation, particularly suitable for applications such as soil removal between bridge piles.

The SJT850 features a high-torque auger head (850 mm specification) with alloy-tipped teeth, providing exceptional cutting force to handle hard soils and complex geological conditions. With a large pumping capacity, it integrates airlift and slurry pumps for efficient slurry transportation. The equipment operates at a power of 55 kW and a working pressure of 16 MPa, making it suitable for deep-water operations. Customization is available to meet diverse project requirements.

With its powerful cutter suction capabilities and highly efficient slurry pumping system, the SJT850 offers significant advantages in underwater operations, especially in tasks like bridge pile foundation construction and submarine pipeline installation.
