Abstract (en)
The present disclosure relates to a cutting drum (24A; 24B; 24C) for a mobile mining machine (10). The cutting drum (24A; 24B; 24C) comprises an outer circumferential face (34) extending between first and second end faces (36, 38). The cutting drum (24A; 24B; 24C) further comprises at least one first support arm (54) including a cutting tool (56) and being pivotably mounted to the outer circumferential face (34). The first support arm (54) is pivotable into a working position, in which the cutting tool (56) of the first support arm (54) is positioned beyond the first end face (36) in a direction of a central longitudinal axis (D) and away from the second end face (38). Thus, for example, material remaining in the interspaces between neighboring cutting drums arranged side by side can be cut by the cutting tool (56) of the first support arm (54).
