Description

A high-tower wind power hoisting crawler chassis tower crane

technical field

The utility model relates to the field of cranes, in particular to a high-tower wind power hoisting crawler chassis tower crane.

Background technique

In the past few years, hoisting machinery mainly crawler cranes and all-terrain truck cranes have completed a large number of wind turbine hoisting operations. The wind power energy industry is dominated by economic scale. The higher the tower is built, the greater the power of the wind turbine, and the faster the return on investment of the wind farm. As wind turbines become larger and higher, more and more wind farms are built in remote areas that are difficult to access, and the space required for installation is getting smaller and smaller. The use of crawler cranes and all-terrain truck cranes The disadvantages gradually emerged. Using conventional crawler cranes and all-terrain cranes is too expensive a solution and requires a lot of logistical work for the company contracting the wind turbine installation. At the same time, the crawler crane is based on the ground and is equipped with a long arm frame so as to reach the height required for wind turbine installation. As the wind energy industry grows, wind turbines are increasingly being assembled on sites that are not easily accessible by large machinery, such as forests and mountain tops. Transporting such a large piece of machinery like a crawler crane into such a site is not easy. For example, when entering the forest, it is necessary to cut down trees to make room for the erection of the 100-150m long boom. When installing the wind turbine, it is also necessary to cut down the surrounding 160m trees for the lifting and lowering of the boom. In addition to the high cost, ecological issues must also be considered. In addition, with the continuous increase in the height of wind turbines, the hoisting height will exceed the operating range of crawler cranes and all-terrain cranes, which brings new challenges to wind power hoisting.

When the existing tower cranes have a high working height, they all use concrete foundation bases, which brings inconvenience to the wind power hoisting operation. The industry has brought certain losses, which is also a difficult problem that tower cranes need to solve urgently in wind power hoisting.
