Reliable Core Transmission: Adopts rigid transmission structure with meshed screw and nut. Power transmission is direct with no slipping risk, ensuring stable and controllable opening & closing operation.
Excellent Positioning Accuracy: The screw moves along a fixed linear track. Combined with travel limit devices, it enables precise control of gate lifting positions with tiny error margin.
Compact & Simplified Structure :Mainly composed of drive unit, reduction mechanism, screw rod, nut and frame. Fewer components lead to small overall size and low occupation of installation space.
Fast & Convenient Installation: Complicated foundation construction is not required; the frame features simple fixing methods. Medium & small units can be installed and commissioned manually to shorten construction periods.
Flexible Driving Options :Three drive modes available: manual, electric and manual-electric dual-purpose, suitable for sites with or without power supply.
Reliable Emergency Operation:All electric models are equipped with hand crank mechanisms. Manual operation is available during sudden power outages or motor failures to meet emergency gate control requirements.


Low Maintenance Cost: Screw and nut are the main wearing parts; only regular lubrication is needed with minimal maintenance workload.
Complete Safety Protection: Standard upper and lower travel limit switches prevent over-travel operation. Selected models are fitted with overload protection to avoid equipment damage caused by excessive load.
Strong Environmental Adaptability :Electrical components reach IP54 or higher protection grade, adapting to humid and dusty conventional working conditions in water conservancy projects.
Easy Operation: Manual models deliver low cranking resistance; electric models feature simple control panels. No professional skills required for regular operators.
Wide Gate Compatibility: Perfectly matched with various medium and small gates including flat gates and cast iron steel gates, with strong universal applicability.
