Precision Lifting for Hydraulic Structures
Water conservancy projects such as dams, canals, and floodgates rely heavily on gate hoists and heavy-duty winches to safely lift and lower gates that control water flow. These machines are vital for regulating river levels, preventing floods, and maintaining hydropower station operations.
At CPWINCH, we manufacture customized dam gate winches and sluice gate hoists to meet the diverse demands of modern hydraulic engineering.
Where Gate Hoists Are Used in Water Conservancy
1. Dam and Reservoir Projects
-
Lifting radial gates, vertical lift gates, and sector gates
-
Releasing or retaining water based on reservoir needs
-
Emergency gate operation during flood discharge
2. Canal and River Control
-
Operating sluice gates in irrigation and navigation channels
-
Managing water levels across different lock sections
-
Debris removal and sediment flushing
3. Flood Control Stations
-
Fast opening of spillway gates during heavy rainfall
-
Controlled closing to maintain downstream water safety
-
Integration with SCADA systems for remote operation
Why Use Heavy-Duty Winches for Gate Lifting?
Traditional mechanical lifting systems cannot handle the massive size and load of modern dam and canal gates. That’s where custom-engineered gate hoists and winches come in.
| Feature | Benefit |
|---|---|
| Large Load Capacity | From 10 tons to 300 tons or more per gate |
| Precise Control | Smooth, adjustable speed for sensitive gate positioning |
| Weather Resistance | Suitable for outdoor, humid, or submerged environments |
| Automation Ready | PLC, HMI, or SCADA integration for smart control systems |
Types of Gate Lifting Systems
1. Screw-Type Gate Hoists
Used for smaller gates or precise positioning. Slow but highly stable. Often manually or electrically driven.
2. Winch-Type Gate Hoists
Common for large radial or vertical lift gates. Powered by electric motors with steel wire rope drums.
3. Hydraulic Gate Hoists
Used in major hydropower plants or for sector gates. High force, fast movement, compact design.
Key Considerations When Choosing a Gate Hoist
-
Lifting Force Required: Based on gate weight, friction, and water pressure
-
Stroke and Lifting Height: Total travel distance of the gate
-
Operation Mode: Manual, electric, hydraulic, or remote-controlled
-
Mounting Location: On dam crest, embedded in galleries, or alongside spillways
-
Corrosion Protection: Galvanized structures, stainless-steel components, IP-rated enclosures

Frequently Asked Questions
Q1: What type of gate hoist is suitable for large dam radial gates?
A1: Winch-type gate hoists with electric or hydraulic drive systems are ideal for large radial gates due to their high capacity and flexibility.
Q2: Can gate hoists be automated?
A2: Yes. CPWINCH systems can integrate with PLCs and SCADA systems for remote and automated control.
Q3: How do I calculate the hoist capacity for a sluice gate?
A3: You’ll need to consider the gate’s weight, water head pressure, friction, and safety factor. We can help with engineering calculations.
