In a hoist frame of a conventional electric hoist, parts are cut into a plurality of parts according to a required size and are integrally formed through welding-based joint, so that the welding defects of a welding structure are difficult to detect through all-number non-destructive inspection, and the management of welding quality is high in cost. In addition, there is a problem that the amount of CO2 discharged is increased due to manufacturing energy during welding. The present invention provides an electric hoist and a crane apparatus having a rope drum around which a wire rope is wound and an electric motor capable of rotating the rope drum, the electric hoist comprising a pair of side plates for holding both ends of the rope drum and a plurality of support shafts constituting a hoist frame, the support shafts being arranged parallel to the shaft of the rope drum, the two ends of the side plate penetrate through the holes formed in the side plate and are fastened to the side plate, so that the welding quality management is not needed, the energy consumption during manufacturing based on welding is avoided, and the CO2 emission amount caused by the manufacturing of the electric winch can be reduced.
现有的电动卷扬机所具有的卷扬机机架将部件按所需的尺寸切断为多个并通过基于焊接的接合形成为一体,因此对焊接构造物的焊接缺陷通过全数非破坏检查进行检测较为困难,焊接品质的管理花费较多的成本。并且存在因焊接时的制造能量而CO2的排出量增加的问题。本发明提供一种电动卷扬机和起重机设备,具有卷绕有钢丝绳的绳索卷筒和能够使绳索卷筒旋转的电动机,其中包括保持绳索卷筒的两端的一对侧板和构成卷扬机机架的多个支承轴,其与绳索卷筒的轴平行地配置,其两端贯通设置于侧板的孔并紧固于侧板,由此不需要焊接品质的管理,并且没有基于焊接进行制造时的能量使用,从而能够减少电动卷扬机的制造导致的CO2排出量。
