How do dragline excavators work?

Dragline excavators operate using a large bucket suspended from a boom, which is typically mounted on a rotating platform. The bucket is dragged towards the machine by a cable system, allowing it to scoop up material from the ground. Once filled, the bucket is lifted and swung to a designated location, where it is released. The combination of the boom's height and the bucket's capacity makes dragline excavators effective for large-scale earthmoving and mining operations.
