Rising Sector Gates

These gates are mainly used for the control of flows and levels in rivers.

Advantages

• Quick operation as they move in an arc.
• The entire water load is transferred radially through the arms to the pivots which gives reduced hoist capacity.
• Gives an unobstructed passage for movement of river traffic.
• Torsionally rigid to allow operation from one side.

Disadvantages

• A recess is required in the floor for the gate to occupy which could be a problem where there is high silt content.
• Internal confined space for maintenance.
• Curved fabrication requires an assembly jig.
