作为大型吊装设备之一, 履带起重机经专门设计后，可用于风力发电机吊装施工。


1. Among the many types of cranes developed over time, the Crawler crane has become critical to the success of the wind power industry. A Crawler is a crane mounted on an undercarriage with a set of tracks that provide stability and mobility. With a capacity of 40 to 3,500 US tons, a typical Crawler used in windmill construction has a boom length of 220' and a 450 ton capacity.

“风力发电施工中常见的履带起重机吊杆长度（boom length）为220'，超重能力可达450吨。”

2. There are different pulleys supplied with the model to allow the boom head to be accurately configured depending on the chosen setup.

“该机型配备不同规格的滑轮组，便于按照选定安装方式准确配置吊杆头（boom head）.”

由此，“风电杆头”整体可理解为：

the boom head used for wind power setup/used in windmill construction

以上信息，请参考。
