Sany Heavy Industry Co., Ltd.: Main and Auxiliary Collocation, Economical and Efficient — — New Trend of Mixed Tower Fan Hoisting

With the rapid development of wind power technology in China,，2020-Three years in 2023，Mainstream Onshore Wind Power Unit Capacity from 2.5~3MWClimb to 5.5~6MW，Even up to 10MW，Maximum height also from 130m~The 140 range has come to over 180.m。

（The data comes from the network：Energy magazine official & Zhonggong Network）

The fan keeps going up.、Focus on development，Under the dual challenges of structure and cost，Mixed-tower fan is used more and more because of its unique advantages.。There is data to show，The winning bid of 140 in 2023mAbove wind power，The proportion of mixed tower fans accounts for 15%，60 of these%Fan height is 160mLeft and right（Concrete tower section 130~140m）。Thus，A new lifting solution has also been created.。

In the near future，Wind Power Project in Dingbian, Yulin, Shaanxi，Adopted by Inner Mongolia Dongran Power Engineering Co., Ltd. SCC15000TM + SAC9000C8-8 The scheme participates in the construction of the project.。

The project consists of 30 sets of 5MWComposition of mixed tower fan，

SAC9000C8-8 using 141.8m（83.8+58)Working condition，Be responsible for the installation of concrete tower body：The 5 installed in the projectMWMixed tower fan，The concrete tower is 131 in heightm，36 sections in total。

Many sections of concrete tower body、Long hoisting operation time，Adopt the master/Lifting scheme of auxiliary equipment——SAC9000C8-8 Installation of concrete tower section，SCC15000TMCarry out steel tower/Cabin/Hub/Blade installation，Can realize the connection of the front and back working procedure、Simultaneous construction of two working faces，Faster than single main crane construction，Lower cost than two main lifting equipment，It has become a new operation scheme for hoisting the mixed tower.。

The technical trend of large-scale fan，Which model will become the mainstream next?，It's 10MWOr 12MW，What changes will take place in wind power hoisting equipment?？Feel free to leave your comments in the comments section.。
