Almighty deputy, ace partner! Telescopic crawler cranes can also dominate wind farms

With the successful assembly and docking of the mixed tower segment at the No. 14 position, the first mixed tower wind turbine of the 70 MW wind power project of Guoneng Lingbi Hugou has been hoisted. Sany SCC15000TM crawler crane serves as the main crane.

The wind farm is located in Suzhou City, Anhui Province, in a low-lying plain area. However, because the construction time is in the rainy season, the rain continues, resulting in the construction area is easy to accumulate water, and the muddy and soft land makes the entry and transition of the main crane a problem.

In order to solve this problem, the construction party hired STB1600T6 telescopic crawler crane as a helper.

Operator Master Huang introduced: "Generally speaking, truck cranes and crawler cranes can be used as auxiliary cranes for wind power hoisting, but the adaptability of traditional truck cranes is poor, and the road must be repaired and steel plate sleepers are paved when entering the site. ”

"If you useTruss boom crawler craneWhen the transition is made, it is necessary to dismantle the boom, disassemble the counterweight, and transport, and a worker cannot complete these tasks at all, which is time-consuming, laborious and costly. In contrast, the telescopic crawler crane is the most ideal choice, it is not afraid of muddy roads, can walk with loads, and a worker can complete the transition. ”

Since entering the site in August this year, the STB1600T6 has performed very well, and with its help, the construction efficiency has been greatly improved.

Mr. Xu, the person in charge of the construction, said: "Before the STB1600T6 enter the site, the auxiliary crane is two truss boom crawler cranes, when disassembling the counterweight of the main crane equipment, these two equipment need to be converted in arm length, and the telescopic crawler crane can be lifted directly to the appropriate length, which can save an hour and a half." ”

◼︎ More comprehensive working conditions:One equipment and one vehicle are used for two vehicles, which can take into account the four tasks of main crane disassembly and assembly, tower tail slip, impeller tail slip and blade support, so as to achieve full coverage of typical working conditions.

◼︎ More efficient construction:The whole vehicle is self-loading and unloading, no need to dismantle the boom, no need to play legs, and reduce an auxiliary worker.

◼︎ Stronger hoisting:Auxiliary 1000-ton main crane unloading truck, 19X blade tail slip without pressure, compared with the same ton of the same type of products, the ability is stronger.

◼︎ Easier transitions:The main machine weighs 79.4t, the retracted width is 3.5m, and the whole machine can be transported by 3 cars, and the middle rail is 4.5m, and the yard can be transferred by itself with counterweight, and the distance of 2km only takes 1h.

With the full cooperation of all parties, the project ushered in a "good start". After the completion of the wind farm, the annual theoretical power generation capacity is 249.22 million kW·h, the annual on-grid electricity is 180.94 million kW·h, and the annual utilization hours are 2585h, which can effectively improve the ecological environment, reduce carbon emissions, and promote local economic development.
