According to the present disclosure, there is provided a hoisting frame for hoisting a transformer or reactor, the hoisting frame comprising a frame wall section 100. The frame wall section extends in a frame wall section plane P. A lift opening 104 is formed within the frame wall section 100, wherein the lift opening axis x1 is oriented normal to the frame wall section plane P. The frame wall section 100 directly surrounding the lift opening 104 has a thickness t that increases as the distance to the lift opening axis decreases. This configuration allows a relatively large surface or contact area to be provided for the edge 106 of the lift opening 104 while avoiding overdesign of the thickness of the frame wall section. Increasing the surface of the edge 106 generally reduces the contact pressure.

    根据本公开,提供了一种用于提升变压器或电抗器的提升架,该提升架包括框架壁区段100。框架壁区段在框架壁区段平面P内延伸。提升开口104形成在框架壁区段100内,其中提升开口轴线x1相对于框架壁区段平面P法向定向。直接围绕提升开口104的框架壁区段100具有随着到提升开口轴线的距离减小而增大的厚度t。这种构造允许为提升开口104的边缘106提供相对较大的表面或接触面积,同时避免对框架壁区段厚度的过度设计。增大边缘106的表面通常减小接触压力。
