The invention relates to a rock processing plant (10) having a process unit (20), to which a working platform (30) that can be walked on is assigned, wherein the process unit (20) has a projection (24.5), which protrudes into the working area formed by the working platform (30), wherein the working platform (30) has a fall arrester (35), in particular in the form of a guardrail, and wherein the working platform (30) has a platform widening (33) in the area of the projection (24.5) to create a working area adjacent to the projection (24.5). To improve occupational safety the invention provides that the platform widening (33) has a floor segment (33.1) as a working surface, which is swivel mounted such that it can be folded or swiveled between a folded-down working position, in which the floor segment (33.1) can be walked on, and an upright transport position, that the fall arrester (35) is guided in the area of the platform widening (33), that at least one locking segment (36.6) is directly or indirectly coupled to the floor segment (33.1) in such a way that when the floor segment (33.1) is moved, the locking segment (36.6) is moved, wherein in the transport position the locking segment (36.6) blocks the access to the projection (24.5) at least in some areas and in the working position the locking segment (36.6) is moved out of the access area.
