This specification prescribes design principle, load, material and mechanism of gate hoist of hydropower projects.
This standard is applicable to fixed gate hoist and mobile gate hoist that mainly adopt electric drive to open and close gate and trash rack in hydropower project. Fixed gate hoist includes different types, such as winding type, screw-rod type, hydraulic hoist and chain-type, and mobile gate hoist includes portal hoist, trolley hoist and bridge hoist.
