Abstract

Es handelt sich um eine Haltevorrichtung für den Transport von Fördergut, insbesondere zum Heben, Transportieren, Schindeln und Stapeln ferromagnetischer Förderteile (1), mit zumindest einem Permanentmagneten (2) zur Erzeugung eines Permanentmagnetfeldes, ferner zumindest einer elektrischen Magnetspule (3) zur Erzeugung eines Temporärmagnetfeldes und Kompensation des Permanentmagnetfeldes, und mit einem magnetisch leitenden Gehäuse (4). Der Permanentmagnet (2) ist in Richtung seiner kleinsten Abmessung (l3) magnetisiert, wobei der Permanentmagnet (2) in Magnetisierungsrichtung (M) rückseitig mit einem Pol (N, S) an dem einen magnetischen Rückschluß bildenden Gehäuse (4) und frontseitig mit dem anderen Pol (S, N) in Richtung auf einen Arbeitsspalt (AS) gegenüber den Förderteilen (1) angeordnet ist. Das Gehäuse (4) weist im Querschnitt drei oder mehr auf einer Grundplatte (5) aufstehende Stege (6) mit jeweils kopfseitig im Bereich des Arbeitsspaltes (AS) befestigten Permanentmagneten (2) auf. Zusätzlich sind zumindest zwei unabhängig voneinander beaufschlagbare Magnetspulen (3) in zumindest einem Stegzwischenraum (7) vorgesehen.
