APPLICATIONS & PROJECT FIT
Is a Radial Gate Right for Your Project?
Radial gates are used to regulate discharge through gated spillways and manage reservoir water levels. Suitability depends on the hydraulic conditions, available installation space and operating requirements of your project.
Spillway Discharge Control
Adjust the gate opening to regulate discharge according to the project's operating plan.
Reservoir Water-Level Regulation
Coordinate gate operation with reservoir water-level targets and downstream discharge requirements.
Installation and Maintenance Access
Review pier geometry, trunnion locations, gate movement clearance and maintenance access before confirming the arrangement.
STRUCTURE & OPERATION
Gate Structure and Operating Principle
A radial gate uses a curved gate leaf connected to support arms that rotate about fixed trunnions. The gate geometry, supporting structure and sealing interfaces must be coordinated with the project's hydraulic conditions and civil layout.
-
Curved Gate Leaf
The curved skin plate forms the water-retaining surface. Its radius and dimensions are defined around the opening, design head and gate arrangement.
-
Beams and Stiffeners
Beams and stiffeners support the skin plate and transfer loads to the radial arms. Their arrangement is part of the project-specific structural design.
-
Radial Arms and Trunnions
The arms connect the gate leaf to its pivot supports. Trunnion positions influence the movement envelope, pier interfaces and hoisting layout.
-
Sealing Interfaces
Side and bottom sealing arrangements are selected to suit the gate geometry, contact surfaces and project leakage requirements.
SPECIFICATIONS & CONFIGURATION
Project Specifications and Configuration
Radial gate dimensions and configuration depend on the opening, hydraulic conditions and installation layout. The following information helps define the gate arrangement and coordinate its structural, sealing and hoisting interfaces.
| Design Input | Information to Provide |
|---|---|
| Opening Dimensions | Clear opening width and height, with drawings where available. |
| Hydraulic Conditions | Design head and relevant upstream and downstream water levels. |
| Gate Geometry | Specified gate radius and trunnion locations, if already defined. |
| Civil Layout | Pier arrangement, installation space and gate movement clearance. |
| Operating Requirements | Required opening range, operating frequency and opening or closing time. |
| Hoisting Arrangement | Preferred hoist type and details of any existing equipment. |
| Materials and Protection | Project requirements for steel materials, corrosion protection and seals. |
| Supply Scope | Required gate components, embedded parts, hoisting equipment and controls. |
| Project Specifications | Applicable design specifications, inspection requirements and required documents. |
If some parameters are not yet available, send the drawings and project requirements you have.

GATE & HOIST COORDINATION
Hoisting System and Control Integration
The gate, hoisting equipment and controls need to be considered together. Define the operating requirements and installation interfaces early to establish a coordinated arrangement for your radial gate project.
Hydraulic Cylinder Arrangement
Review cylinder mounting positions, connection points and the stroke required throughout the gate's operating range.
Gate and Hoist Interfaces
Coordinate gate lifting connections, hoist supports and civil interfaces using the project layout and equipment drawings.
Control Requirements
Specify local or remote operation, position feedback and coordination between lifting points according to the project's operating requirements.

WORKSHOP & FABRICATION
Fabrication and Pre-Assembly
Fuda’s workshop brings together the curved gate leaf and support structure during radial gate fabrication and pre-assembly. This stage provides an opportunity to review component fit and assembly interfaces against the project drawings.
-
Curved Gate Leaf Fabrication
The curved skin plate, beams and stiffeners form the gate leaf assembly, with geometry defined by the project drawings.
-
Support Structure Pre-Assembly
Bringing the gate leaf and support arms together allows their relative positions and connection interfaces to be reviewed before subsequent assembly stages.
-
Inspection and Documentation Requirements
Specify the dimensional checks, weld inspections, coating records and other acceptance documents required for your project when defining the supply scope.
