ABSTRACT:
A dragline includes a boom, a bucket, a hoist rope from which the bucket is suspended from the boom, and a drag rope for dragging the bucket. Data is produced on the alignment, with respect to a vertical plane containing the boom axis, of at least one of the following dragline components:i) the hoist rope;ii) the drag rope;iii) the boom;iv) the bucket.This data can be used for controlling the load condition on the basis of the dragline.The data can be inputted to a man-machine interface, e.g. a display device, controlled by a human operator, and/or it can be inputted to control the drive of the hoist rope and/or of the drag rope, so as to decrease or cease drive in response to detected misalignment of dragline component(s).
