Movable Weir

A structure to use and govern water by erecting or inverting a sluice gate installed in a waterway or river

Installed in waterways or rivers, it distributes the pressure of hydraulic devices in a standing or inverted form to improve operating efficiency.
By applying watertight rubber fittings, it prevents breakage of water-resistant rubber due to foreign substances and increases the convenience of maintenance.
Installation of a foreign substance prevention plate (advantage)
1. Blocks foreign substances into the movable weir and protects hydraulic actuators and various internal devices.
2. Blocks sediment accumulation caused by vortex during overflow, and it is easy to open and close the movable weir.
3. Reduces noise from falling water by adjusting the angle of the inflow prevention plate.
Remote automatic operation is possible in the event of flooding.
Emergency road recovery is possible with an emergency engine in case of localized heavy rain or power outage.
