The present invention relates to a movable pole extension (4) for a magnetic clamping apparatus (1) for holding a ferromagnetic workpiece (P), comprising a fixed pole member (5) extending in a predetermined longitudinal direction (X-X) and at least two pole members (6, 7) attached to said fixed pole member (5), said at least two pole members (6, 7) being movable relative to said fixed pole member (5). The movable pole extension is characterized in that it has holder means (8) operably coupled to said fixed pole member (5), wherein said holder means (8) are movable in said predetermined longitudinal direction (X-X) between a first operating position (Pl) and a second operating position (P2) and operate on said at least two movable pole members (6, 7) to hold them in coupled contact with said fixed pole member (5).

A holding device for lifting and/or moving an article comprising at least one substantially plane outer surface is disclosed. The holding device is designed for mounting on an implement carrier which comprises a carrier part including connecting means so that the holding device can be mounted on the implement carrier and released from the implement carrier, and at least one holding unit which is arranged so that the at least one holding unit in a contact position can come into contact with the article and can grip the article by surface contact between the at least one holding unit and one outer surface of the article to be lifted and/or moved. The carrier part comprises at least one backstop against which the article can rest when the article is to be released from the at least one holding unit, whilst the at least one holding unit is movably mounted to the carrier part so that the at least one holding unit can be moved relative to the at least one backstop. The holding device further comprises at least one actuator for moving the at least one holding unit relative to the at least one backstop.

摘要:
A magnetic lifter includes at least one dipolar mobile pole (1) consisting of two ferromagnetic pole pieces (2, 3), joined through an elastic connection, and inserted between two fixed opposite polarities (5, 6) of an electromagnet (7) so as to be able to slide within a housing (8) formed therebetween. By using as mobile poles (1) dipoles which slide between two poles (5, 6) of opposite polarity the closure of the magnetic circuit occurs within the single mobile pole (1) whereby the contact losses are reduced to half and it is possible to lift even small- and medium-sized loads with the greatest ease. Moreover, thanks to the elastic connection between the two pole pieces (2, 3) which allows a change in their mutual distance, upon activation of the lifter the two pole pieces (2, 3) tend to move away from each other until they adhere through magnetic attraction each one to its own adjacent polarity, thus canceling the air gaps and the consequent leaks as well as the risks of sliding.
