Abstract

A mineral material machining plant includes a hydraulic element including a connection area and a passage opening. An overload protection device includes a replaceable burst panel covering the passage opening. The burst panel includes a rear face, at least one bore, and at least one recess having a lateral insertion section open towards one side of the burst panel. A burst panel holder engages the rear face. In an assembled condition at least one fastening bolt passes through a bolt mount of the burst panel holder, the bore of the burst panel, and is threaded into a threaded mount of the connection area. In a disassembled condition at least one retaining element connects the burst panel holder to the hydraulic element and can be inserted laterally into and removed from the recess transversely to a plate plane of the burst panel.
