Slide roller gates are normally used to shut of large openings and high water loads. They are commonly used as protection mechanisms at hydraulic power stations where they can also be used as a regulation mechanism for the turbine coupling with the network. It is a gate formed by a strong reinforced fabricated structure, for which the guiding system works using a side roller system which reduces the gate`s operation loads.
