The mobile fixed-type double-lifting-point winch hoist is a hydraulic equipment that combines mobile and double-lifting-point designs, primarily used for the synchronous opening and closing control of large gates. Its core features include:
Structural Characteristics
It adopts a double-lifting-point design, synchronously driving two lifting points via a rigid connecting shaft to ensure balanced force on both sides during gate lifting and lowering, preventing deformation. The mobile structure allows flexible movement along tracks, supporting alternating operations of multiple gates, thereby enhancing operational flexibility.
Functional Advantages
Synchronous Control: Particularly suitable for gates with spans exceeding 10 meters, with a height difference controlled within 3 millimeters, ensuring balance in high-precision scenarios such as radial gates and miter gates.
High Load Capacity: Custom models can support the opening and closing of gates exceeding 200 tons, meeting the mechanical demands of large-scale hydraulic engineering projects.
Dual Braking System: A combination of electromagnetic and hydraulic braking ensures the gate position remains locked even during power outages, enhancing safety.
Applicable Scenarios
Commonly used in hydraulic hubs requiring frequent gate switching (such as multi-gate systems), large hydropower stations, and miter gates in ship locks, where high synchronization and stability are critical.
