履带式起重机具有起重性能好、起升高度与幅度大、动作平稳、接地比压小、可带载行走、安装拆卸方便、工况组合多等多个优点,广泛应用于电力、核能、石油化工、桥梁、市政、风力发电等行业。履带式起重机兴起于20世纪50年代,70年代得到迅速发展。80年代后,随着美国和德国等工业强国研发投入的增加,履带起重机技术发展很快,一批技术先进、载荷谱齐全、性能可靠的履带起重机得到了广泛应用。目前,美国的特雷克斯德马格公司和马尼托瓦克公司及
Crawler crane with lifting performance, lifting height and amplitude, smooth operation, grounding pressure is small, can carry carrying, easy installation and removal, combination of multiple operating conditions and more, are widely used in electric power, nuclear energy, oil Chemical industry, bridges, municipal services, wind power and other industries. Crawler cranes rose in the 1950s and developed rapidly in the 1970s. Since the 1980s, with the increase of R & D investment by industrial powers such as the United States and Germany, the crawler crane technology has developed rapidly. A batch of crawler cranes with advanced technology, complete load spectrum and reliable performance have been widely used. Currently, the United States Terex Demag and Manitowoc companies and
