Abstract

An apparatus (2) for crushing items like large stones, rock pieces, steel slag or concrete, comprises a tubular housing (6) intended mainly for vertical disposition, a lifting device (16) with a connecting coupling (14) suspended in lifting wires (12) and arranged to be coupled with an upper end of a heavy hammer head (32) with the purpose of elevating this so that the hammer head (32) may be released at an elevated level and be allowed to fall freely down against an item to be crushed, where the connecting coupling is constituted by an electromagnetic coupling (14) comprising an electromagnet arranged to be moved towards an upper end of the hammer head (32) and to be coupled with it by actuating the electrmagnet (14), and where electrical cables for supplying the electromagnet are woven into the wires (12) or otherwise integrated in them. Furthermore, there is disclosed a hammer head for use in the apparatus and consisting of several parts which are clamped together bxy means of a number of longitudinal stay bolts. By simple means is hereby achieved an apparatus where disadvantages connected with prior art are avoided. A significant feature is the mechanical simplification of the coupling which according to the invention can be without any movable coupling parts and also means a much improved efficiency and considerable facilitated operation.
