Sany wind turbine + Sany main crane, independently supporting the challenge of 185m the country's highest mountain mixed tower wind power



On April 26, in Lingchuan County, Jincheng City, Shanxi Province, Shanxi Goldwind Tianyi New Energy Lingchuan Phase I 100MW wind power project, with the 93t nacelle successfully docked on the 185m tower, China Energy Construction Xinjiang Power Construction successfully completed the country's first 185m mountain mixed tower wind power challenge.

The project adopts Sany Renewable Energy 6.25WM fan, mixed tower structure, concrete tower 36 ring height of 130.6m, the upper section of the steel tower, hub center height of 185m, impeller diameter of 220m, nacelle weight of 93t.

For why the choice of crawler crane, Shanxi Jixin hoisting general manager Zhang Jianfu said: "This height is currently only 4000 tons of full ground and 18000 (t.m) crawler can do, now a 4000 tons of vehicles are very tight, and its rent is more expensive." The other is that this is the first 185 meters of mountain wind power, this mountain is not like the plain, the wind changes very quickly, the crawler crane has a natural advantage in wind resistance, plus this 18000 lifting capacity is very strong, we use this 198 + 9 super wind power working conditions (HJHEDB_ZCK), the load is 198 tons, the safety margin is close to 40%, absolute insurance. ”

"Although the parts of the crawler crane are more, but as long as the planning is very fast, we have designed the sequence and streamline of the site and the transport vehicle, and installed one on the one, not blocking the road, very smooth, the time used to group the car is about 90 hours, which is very fast in mountain wind power. The disassembly and assembly design of Sany this car is very good, and it is very humane, like the aluminum alloy used on their big arm, or widened, and there is a safety rope, which is very secure for the safety of our workers when they receive the arm in the air, and their pin hole accuracy is also very high, and the pin is relatively smooth, which improves the work efficiency of workers. ”

At 13:29, the cabin slowly left the ground. After 29 minutes and 47 seconds, the nacelle landed steadily on the top tower and began to connect the flange surface, and the mountain wind power ushered in a new height. Zhang Jianfu, general manager of Shanxi Jixin Hoisting, said happily: "The successful completion of the project is also another test of our professional ability, new energy construction is the focus of the country's future, we also hope to participate in this construction through their own professional services, with first-class equipment, first-class technology and first-class service, grasp the opportunities of the times, and follow the development of the country to make the enterprise better and better." ”
