Dredger ADST-400Е

CHARACTERISTICS: Dredgers With submersible pumping unit DESCRIPTION : The dredger with submersible dredge pump DP100B produced by Toyo with the capacity by pulp reaching 400 m3/h, while the output by soil is not less than 100 m3/h, at the head of up to 30 m.w.c. ADST-400Е is designed for: Excavation of 1-3 categories’ soils; Recovery of sand and other non-ferrous materials; Aggradation of dikes, roads, construction sites; Dredging operations. Thanks to the application of a submersible pump as soil intake technology without suction pipeline, it is possible to extract and handle the pulp with the sand output up to 30% by volume of nominal capacity. This dredger can recover 100 m3 of wet sand and discharge it to the dumpsite located at the distance of up to 500 m, while the dredger pump power consumption is 75 kW. The depth of dredging reaches 30 meters. The total installed power of the dredger is 135 kW. Dredger power supply - three-phase, from the shore 400 V grids. The system of the dredger electric equipment and automation ensures all electro-technic protection measures, as well as control of current consumption and input voltage. The dredger is protected against possible heeling and water availability in bilges. The device detecting the availability of water in pontoons will inform the staff about its penetration. The dredger can work in semi-automatic mode employing an industrial programmable logic controller which ensures the operation within the range of admissible pump current consumption and in permanent contact with the soil.
