ALUMINIUM ROLLER GATE.

The gate consists of a skin, welded or riveted to a channel frame and cross bracing. Normally 4 to 6 flanged rollers brushed with tufnol or a similar water lubricated synthetic turning on stainless steel shafts which run in cast iron guides set in reinforced concrete walls.

Gate Operations : By lifting gears (either motorized or manual operated ) through wire ropes, wire rope drums and gear box.

Functions : Tidal gates and many headworks and barrages are of this design.

SCREWDOWN GATE.

The gate consists of pieces of hardwood bolted together and framed in a mild steel or cast iron channels. The top of the gate is attached to a spindle threaded at the top portion which moves inside a fixed bearing and so that it moves up and down as the operating wheel is turned. The gate slides up and down against the C.I guide embedded into the concrete structure. The dimension of the Screwdown gate is normally limited to 6’ x 6’. Sometimes the material used for the whole gate is Stainless steel.

Gate Operations : Operate Manually and Electrically.

Functions : Irrigation and drainage controls.

RADIAL GATE

Quite similar to roller gate except:-

Instead of rollers, the gates have arms which are pivoted at both ends. Thus the gate moves through a circular arc ( rubbing against rubber strips made of curved cast iron strips set in concrete walls) instead of up and down motion through rollers.

Normarlly there is no counter weight since the effort required to operate this type of gate is much less.

The skin of the gate is curved ( i.e. radial ) instead of a straight plate.

This type of gates are commonly used for head works.
