Kherson Factory of hydraulic dredgers manufacturing specializes in building of hydraulic dredgers of HCC brand under the projects agreed with the Shipping Register of Ukraine, re-equipment and modernization of hydraulic dredgers of any brand. Besides the enterprise has a Certificate of compliance with the standards of the Shipping Register of Ukraine related to the realization of building, re-equipment, modernization and repair of the ships, hull structures, ship equipment.For the purpose of protection of copyrights for produced products the enterprise registers the results of its own intellectual creativity for profitable models at the State Register of Patents of Ukraine.Dredger (hydraulic dredger) is a water craft for underwater development and dredging of soil, extraction of different materials (gravel, sand, sapropel, precious metals, etc.) From the bottom of different water basins.Hydraulic dredgers are successfully applied in different branches:cleaning of water bodies (ponds, rivers, lakes etc.)extraction of sand and gravel from the open-pit mine, sapropel from the lake,precious metals (gold and diamonds) extraxtion;alluviation of earth dams, dikes and beeches;extraction of building materials and minerals;development of underwater trenches for pipelines (pipe canal) and cables installation and its alleviation;alleviation of roads and areas for industrial and civil building;development of ashy and sludge tanks;development of coal sludge pits, iron and steel plants, coke-chemical enterprises;production of fine-grained concentrate from sludge pits of mining and concentration complexes; cleaning of industrial and agricultural sludge tanks from sludge, sand and other depositions.hydro-mechanized works during the erection of ship and irrigation canals, water area buildings, sea and river ports.Hydraulic dredger is a heavy pump, assembled on floating pontoons. The variety of kinds of performed works and areas of using causes the variety of models of hydraulic dredgers, depending on:- Natural conditions under which the hydraulic dredger is used;- Categories of soils;- Depth of development;- Distance of transportation and height of soil lifting;- Possibilities of energy supply;- Type of aggregate for suction;- Way of soil intake;- Way of soil transportation;- Controlling system;- Hull construction;- Place of location of the main equipment (bilge or hydraulic dredgers with sunk dredge pumps);- Quantity of dredge pumps (one-pumped or two-pumped hydraulic dredgers);- Availability or absence of living and domestic structures of the board of the hydraulic dredger.Productivity of hydraulic dredgers is different - from 6 m3 per hour to 450 m3 per hour of the soil, depth of the development from 0,5 to 5 ... 15 meters from water surface.Board equipment from power units to metering apparatus is modern. The control of all mechanisms of hydraulic dredgers is performed from the deckhouse of the burgomaster by means of control panel located there and equipped with the correspondent devices. All regular disconnections conditioned by the technological process of works performing are executed by means of control panel. The control panel allows performing of an emergency stop almost of all mechanisms of the hydraulic dredger.The enterprise follows the main guidelines such as: the State Standard of the Union of Soviet Socialistic Republics "Hydraulic dredgers of general purposed. Terms and definitions. All-Union Sate Standard 17520-72 ", All-Union Sate Standard 26433.0-85" Order of measurement performing.
