Compact Structure :The gate leaf is welded by face plate and beam grid with neat and regular components.
Wide Versatility: Suitable for all kinds of hydraulic openings in channels, reservoirs, pump stations, sewage treatment plants and more, with a wide range of size spans available.
Easy Installation ;Standard embedded parts are pre-buried in gate slots; hoisting and alignment procedures are simple to shorten construction periods.
Convenient Inspection & Maintenance :The flat smooth gate surface allows easy flushing of sediment and debris. Sealing and traveling components can be replaced separately.
Excellent Water Sealing Performance :Equipped with P-type rubber water stops that closely fit embedded tracks, with leakage volume fully compliant with industry standards.
Diverse Gate Types: Available in open-top, submerged and vertical-horizontal lifting styles, with single-lifting-point and double-lifting-point layouts for selection.
Wide Compatibility with Drives: Matches screw, winch and hydraulic hoists, easy to realize automatic remote control.
Customizable Anti-Corrosion Performance :Zinc spraying and heavy-duty anti-corrosion coating are optional to resist long-term water corrosion and sediment abrasion.
Labor-Saving Fixed Wheel Operation: Rollers roll along tracks to greatly reduce friction, ideal for large gates requiring frequent opening and closing.
