The hoisting and closing machines are designed for lifting flat gates, widely used in drainage and hydraulic projects, hydropower engineering, capable of lifting and lowering steel and flat gates to achieve gate opening and closing. The New County Rongchuang Hydraulic Machinery Factory offers various types of hoisting and closing machines, including: QPQ general hoisting and closing machine, QPK rapid hoisting and closing machine, QPG high-lift hoisting and closing machine, QPT trolley-type hoisting and closing machine, QPM gate-type hoisting and closing machine, and QH arc gate hoisting and closing machine. These machines are further categorized into: flat gate hoisting and closing machines; arc gate hoisting and closing machines; double-point hoisting and closing machines; rapid hoisting and closing machines; mobile trolley hoisting and closing machines. The double-point hoisting and closing machines are available in two types: centralized drive and individual drive. The hand-cranked and electrically operated hoisting and closing machines come in specifications of 5 tons, 8 tons, 12 tons, 16 tons, and 25 tons, while the electrically operated models range from 40 tons to 200 tons, customizable to user requirements. The factory can also produce double-point hoisting and closing machines, a specialized hydraulic engineering equipment, widely used for gate opening and closing in hydraulic projects. It is suitable for irrigation, aquaculture, agricultural development zones, wastewater treatment plants, hydropower stations, reservoirs (including sluices, embankments, tunnels, and pipelines), and is usable in mountainous, plain, and electrified or non-electrified areas. Additionally, the factory produces cast iron gates, hoisting and closing machines, gate operators, steel gates, screw hoisting machines, hydraulic hoisting machines, flip gate valves, check valves, rotating cleaning machines, spiral conveyors, and various specifications of cleaning equipment, making it a professional hydraulic machinery manufacturer.
