Development of a Semi-automatic Lifting Maintenance Platform in Geheyan Hydropower Station
The thrust bearing of the hydro-turbine unit in Geheyan Hydropower Station is of numerous parts,small size,heavy weight,and limited maintenance space that the lifting equipment is not able to operate.Thus,a semi-automatic lifting maintenance platform based on hydraulic system is developed for the rapid extraction,transportation and re-instal-lation of the thrust pads,as well as the transportation lifting work of the brakes.The introduction of this platform greatly reduces the operation difficulty,shortens the work cycles,and improves the maintenance efficiency of the generators.
