Abstract: PURPOSE: An electromagnetic chuck connection switch for a mobile crane is provided to facilitate the replacement of an electromagnet with the magnetism weakened, thereby reducing maintenance cost. CONSTITUTION: An electromagnetic chuck connection switch for a mobile crane comprises a first member(10) and a second member(10'). The first member is connected to a terminal(30) of a cable drawn out from a battery of a mobile crane and embedded with a magnet(12). The second member is coupled with the first member by the magnetic force generated by the magnet and transmits power from the battery to the electromagnetic chuck of the mobile crane. The first member comprises an assembled band formed of a pair of rectangular parallelepipeds coupled opposite to each other, a circular hole formed by the assembled band, a ball protruded on a part of the interior of the hole, and a magnet. The leading end of the second member is inserted in the hole and has a hole on a side thereof in which the ball of the first member is inserted.

Abstract: PURPOSE: A switch of an electromagnetic chuck for a cargo crane is provided to reduce management cost by replacing only the magnet when the magnetic force is weakened. CONSTITUTION: A first member(10) with a magnet(12) is connected to a terminal(30) of a cable drawn from a battery of a cargo crane. A second member(10`) is coupled with the first member by the magnetic force of the magnet, and transmits the power from the battery to an electromagnetic chuck. The first member has a magnet receiving groove(11), and a cover(13) is screwed to secure the magnet in place in the magnet receiving groove.

Abstract: An electromagnetic chuck of a cargo crane is provided to reinforce the magnetic force of an electromagnetic chuck by reinforcing the strength of the magnetic field of an inner corner and an outer corner of the electromagnetic chuck and an edge of a core. In an electromagnetic chuck, a core(22) on which a coil(21) is wound is positioned in a case(10). The core or the case is rectangular. The magnetism at a weak magnetic force distributing portion in the electromagnetic chuck is reinforced by attaching the core, the case, or a connecting unit formed of the same material as the core. The connecting unit is an extension member(31) having a plate-like bar shape. One end of the extension member is attached to a corner of the core and the other end thereof is attached to the corner of the case to connect the core and the case.
Abstract translation: 提供货物起重机的电磁卡盘以通过增强电磁卡盘的内角和外角以及芯的边缘的磁场的强度来加强电磁卡盘的磁力。 在电磁卡盘中，其上缠绕有线圈（21）的芯（22）位于壳体（10）中。 核心或外壳是矩形的。 电磁卡盘中的弱磁力分配部处的磁性通过附接芯，壳体或由与芯相同的材料形成的连接单元而得到加强。 连接单元是具有板状条形的延伸构件（31）。 延伸部件的一端连接到核心的角部，另一端连接到壳体的角部以连接核心和壳体。
