Overview

We have 4 series of hoists which are  
flat-type gate hoist winch
fast gate winch hoist
radial gate hoist 
direct screw hoist

All series have single and double lift points, single and central drive, and manual and electronic control. 
Various machinery are widely used to open and close all kinds of flat gate, radial gate and quick gate in hydro power, shipping, urban water supply and drainage, flood discharge, sewage treatment, aquaculture and irrigation and water conservancy construction. Medium-sized radial gate has full range and features reliable performance. All products have production licenses, and in strict accordance with the 'Water Conservancy and Hydropower Project Hoist Manufacture, Installation and Acceptance Test Specification' and 'Water Resources and Hydropower Engineering Manufacture and Installation of Steel Gates and Acceptance Norms'.
