The double-lifting-point screw hoist is a key equipment in hydraulic engineering used to control the opening and closing of gates. Its core features include a double-lifting-point design, dual manual and electric operation functionality, and a high-strength structure.
Core Design
It adopts a double-lifting-point structure, enabling synchronous operation of two hoists through an intermediate connecting shaft and an elastic coupling. Compared to a single-lifting-point design, it significantly enhances operational stability, prevents equipment shaking or deformation, and is particularly suitable for high-pressure scenarios such as large-scale hydraulic hubs.
Functional Characteristics
Dual Manual and Electric Operation: Supports manual operation (e.g., hand cranking) and electric control (remote operation), adapting to scenarios without power supply or during sudden failures.
Automated Control: Equipped with safety devices such as magnetic locks and specialized wrenches, enabling precise displacement control and anti-theft functionality.
Material and Craftsmanship: The screw is made of high-strength steel, offering corrosion resistance and wear resistance, suitable for long-term frequent lifting actions.
Applicable Scenarios
Widely used in projects such as urban flood control, farmland irrigation, hydropower stations, and sewage treatment plants, it can accurately regulate water levels or control water flow, ensuring the safe operation of facilities.
