Review of dragline operation experience in extraction and loading of rocks directly to trucks or railroad cars shows that loading is only feasible at the largest radius of the bucket dump when the drag ropes are totally slackened while the lifting ropes are approximately in vertical position. The currently known designs of extracting-and-loading draglines are structurally excessive as they have, alongside with bucket lift and linkage drives, additional power drives and their controls, including processor systems, which never participate in rock cutting and, thus, increase energy consumption of the process. This article studies operation of an extracting-and-loading dragline with tipping bucket set in a cradle, with conventional harness, two power drives to lift and pull the cradle equipped with connection bolt with the tipping bucket. Using tense lifting and drag ropes, the bucket is placed and fixed above a truck positioned in the zone under the dragline boom, which is laterally bounded by the radii of the maximum and minimum dump heights. At the moment of unloading, the bolt is pulled out by low-power winch using rope. Dragline equipped with such buckets can effectively load rocks in dumpcars, crusher hoppers and dump trucks without change in installed capacity of power drives of lift and pull winches, which will greatly expand their technological capabilities.
