缆索起重机(以下简称缆机)由于它是以挠性的承载构件承载索为基础的一种特殊起重运输机械,具有吊运范围大、生产率高等突出特点,从而被广泛地用于大中型采矿场、林木场、港口码头、桥梁建筑等,特别是水电工程的大坝混凝土施工中。目前国内缆机使用为数不多,然而从国外资料反映,特别是高速缆机出现后,采用缆机作为吊运 Cable crane (hereinafter referred to as the cable machine) because it is a flexible load-bearing member based on a special lifting transport machinery, with lifting a large range, high productivity and other salient features, which are widely used in large and medium-sized mining Field, forest farms, port terminals, bridge construction, especially in the dam concrete construction of hydropower projects. At present, there are only a few cable makers in China. However, from foreign sources, especially after the emergence of high-speed cable machines, cable machines are used as lifting carriers
