Sany Heavy Industry; This device is a bit awesome! Look at it to solve the problem of limited space.

China Resources Fengtai County Shangtang Wind Power Project is located in Fengtai County, Anhui Province.，The total installed capacity of the wind farm is 200MW，The structural type of the Wind Turbine is steel-concrete tower.。This time，SCC15000TMResponsible for the installation of the project within 5.27MWThe fan，Fan hub height 160m，Impeller diameter 186m，Leaf tip up to 253m。

Because the construction location is close to the pond of Ganghe River，The venue is small、Construction location is limited，The whole hoisting process，The most challenging task is，Without the assistance of other lifting equipment，Just bySCC15000TMOne main crane，Complete the assembly of the blade safely and efficiently。

SCC15000TMEquipment operator Shi Qimang introduced.：“The most difficult part of this hoisting isSingle blade too long，Reached 93 meters，Due to limited space，When installing the last blade，Equipment cannot be moved for docking installation。”

“After we calculate by measurement,，Find a fixed point to place the super-lift tray，And then rehearsed it many times.，After determining that the scheme is feasible,，To begin the final installation work.。Firstly, the blades are pulled out by the main lifting equipment，Rotate to the fixed point for placing the super-lift tray，Then hang up the super-lift of the main lifting equipment，By lying on the pole and other actions.，Butt assemble the last blade。”

In order to meet the construction of special environmental location，SCC15000TMLarge and small tray separation technique is used，When lifting in a narrow and restricted area，Using Small Tray to Realize the Rotation of Super-lift Counterweight，Meet the construction requirements of narrow environment，At the same time, the super-lift counterweight is disassembled and assembled efficiently.，Shorten the lifting time at the same time，The installation efficiency is greatly improved.。

SCC15000TMEquipment operator Shi Qimang said.：“When lifting the fan blade，The working condition of the equipment is that the main arm 165m+12mTake the super lift，The counterweight is a rear counterweight of 230 tons.+Central counterweight 80t。The total weight of the whole blade is 140 tons.，Lifting height of lifting blade is 160mCarry out butt joint installation。”

The hoisting of high tower and large fan requires high lifting equipment.，In the past, it was necessary to use double-arm working conditions to meet the requirements.，However, the efficiency of disassembly and assembly under double-arm working conditions is very low.，It seriously restricts the efficiency of equipment construction.。And this oneSCC15000TMThe ability of wide arms not only exceeds the ability of double arms.，Disassembly and assembly efficiency is also greatly improved by 50 percent%Above。

Huarun Fengtai County Shangtang Wind Power Project is expected to install 38 Wind Turbines and build a new 220KVBooster station，After the completion of the project, it can effectively promote the local social and economic development.，Improving the local energy mix。After completion, the wind farm is expected to provide 4% clean energy for the power grid every year.700 million kilowatt hours，14 million tons of standard coal can be saved annually.、450 tons of carbon dioxide emission reduction。
