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 calculations are experimentally verified by using data obtained from a one twentieth scale physical model. Predictions of the contours of constant bucket “carry” angle are presented for a full size bucket on a Marion 8050 dragline and compared with the results published by Knights and Shanks (P. Knights, D. Shanks, Bucket rigging influence on dragline productivity, The Australian Coal Journal 36 (1992)).
