Calculation of dragline bucket pose under gravity loading

This paper presents a method by which the pose and internal rigging forces may be calculated for a dragline bucket throughout its workspace, These cal culations are experimentally verified by using data obtained from a one twe ntieth scale physical model, Predictions of the contours of constant bucket "carry" angle are presented for a full size bucket on a Marion 8050 dragli ne and compared with the results published by Knights and Shanks (P. Knight s, D. Shanks, Bucket rigging influence on dragline productivity, The Austra lian Coal Journal 36 (1992)). (C) 2000 Elsevier Science Ltd, All rights res erved.
