摘要： A novel dragline is provided which is equipped with hopper means and loading means. More specifically, the dragline of the invention comprises a hopper means mounted on the front portion of a revolving frame rotatably mounted on a mobile base, the hopper means receiving rocks and stones, soil and sand, minerals and the like dug and carried by a bucket, a guide means for guiding the bucket to a position over the hopper means so that the excavated material is loaded into the hopper means, and a loading means disposed below the hopper means for receiving and transferring the material into another transport means, at least the downstream end portion of the loading means being pivotable. The dragline of the invention makes it possible to dig rocks and stones, soil and sand, minerals, etc. in an efficient manner on a large scale and to load them into a transport means.
