47 Sany cranes to build a 10,000-ton steel structure workshop

"As a big steel country, China exports a large amount of ordinary steel every year, but also imports a large number of high-quality steel. In order to change the status quo of big but not strong, the steel industry must unswervingly take the road of high-quality and reduced development. ”

In November 2020, Chengdu Metallurgical Experimental Plant Co., Ltd. responded to the policy call and took the opportunity of "retreating from the city to the park" to carry out an upgrade and transformation, investing 4.5 billion yuan to build a new plant covering an area of 1,000 acres. At present, the steel structure roof and the steel structure of the supporting plant are being hoisted.

Director Tang, the person in charge of the equipment of Sichuan City Star Machinery Installation Co., Ltd., introduced: "The total lifting weight of the steel structure of the project is 25,000 tons, the weight of a single main steel structure is 64 tons, and the lifting height is 50 meters.At the site, only a grid of 5-8 meters is reserved between the criss-crossing steel beams and steel columns. The volume is large and the difficulty is high, which puts forward new requirements for hoisting equipment. ”

"After strict selection and control, the project department decided to choose Sany.Since the first equipment entered the site in December last year, the project has successively ushered in a total of 47 Sany SCC3200A, SCC2600A, SCC2000A, SCC1500A, etccrane。”

Installation docking is the most critical step in steel structure hoisting, which directly affects the stability of the overall structure.

Sany SCC2000A crawler crane operator master said: "We used the 52-meter main boom + 34-meter tower boom operation condition to complete the installation of a steel structure with a span of 30 meters and a weight of 28 tons.The working distance is long, and the one-time docking point is complex.The lifting performance of this equipment is very strong under the overall operation, and the fretting motion is very good.”

After the completion of the project, on the one hand, it can produce vanadium-containing high-strength and high-quality steel while absorbing solid waste such as urban scrap steel, and provide high-quality materials for social infrastructure. On the other hand, the factory environment that can realize modernization, green, environmental protection and ecology feeds back to the construction of green park cities, making "steel makes cities better" a reality.
