Abstract
An adaptor is provided for a jack assembly having a lifting jack carrying a horizontal plate for raising and lowering a heavy component supported by the jack assembly. The adaptor includes a horizontal support plate fastened to and vertically offset from the horizontal plate of the jack assembly by a height. A plurality of elongated arms is slidably mounted between the two plates to move in a generally horizontal plane. Each of arms includes a holding assembly configured to engage portions of the component supported on the support plate to stabilize the component as it is raised and lowered by the jack assembly. The arms are supported in the height between the two plates at different heights so that the arms are capable of a wide range of rotational and linear movements to adjust the position of the holding assembly of each arm relative to the heavy component.
