The invention discloses a forcibly-opened permanent magnet crane. The front face of a magnetic circuit of an internal magnetic pole is forcibly snapped by using great mechanical force so as to achieve the magnetizing or demagnetizing function, and the permanent magnet crane has the advantages that the structure is simpler, labor-saving and material-saving compared with the prior art, a magnetic block is arranged in a relatively closed protected space, the installation is convenient, and the maintenance is simple; and under the same appearance, the magnetic force can be multiplied.

    强开式永磁吊。本发明利用机械巨力强行将内部磁极的磁路正面拉断,以达到上磁或消磁的功能,其优点是:结构比以往的更加简节,省工、省料磁块设置于相对封闭的被保护空间,安装方便,维修简单;在同等外形下,磁力可成倍增加。
