一、发展概况轮式起重机是从轨道起重机发展而来的——先是轮胎式,后来发展汽车式,七十年代在轮胎式的基础上又发展出越野式,八十年代初期又把越野式的公路行驶速度提高到接近于汽车一般行驶速度而发展出所谓全路面或全地形(All Terrain)式。到目前为止,轮式起重机的发展趋势可概括为:大型、专用、液压、多能、安全、适应,十二个字。大型是指起重能力朝大吨位发展。七十年
I. Development Overview Wheeled cranes were developed from track cranes - first in the form of tyres and later in the automotive industry. In the 1970s, off-roads were developed on the basis of tyres. In the early 1980s, they were also off-road. The road speed has been increased to be close to the average speed of the car and the so-called all-terrain or All Terrain type has been developed. So far, the development trend of wheeled cranes can be summarized as: large-scale, dedicated, hydraulic, multi-energy, safety, adaptability, and 12 characters. Large-scale refers to the lifting capacity of large-tonnage development. Seventy years
