Simulation of the dragline bucket of a Liebherr HS8100.2 crawler crane excavating gravel. The bucket and the spreader bar are modeled as 6-degrees-of-freedom (6-dof) geometries, while the chains and ropes are modeled as bonded spherical particles. The motion of the assembly is controlled by translating the hoist coupler and to the drag coupler. The drag rope can slide on the pulley of the hoist coupler and therefore control the tilting of the bucket.
