Abstract:
Apparatus and methods are provided for extracting surface components having an attachment and installed within a surface. In one embodiment, a tool includes a cross member located between a lifting device and a lift plate having an engagement for engaging the attachment. A lift member extends from the lift plate extending through the cross member so as to engage the lifting device so that the lift member is mounted for tilting displacement with respect to the cross member. In another embodiment, a tool for extracting a surface component includes a cross member engaged by supports extending to the surface, for supporting the ends of the cross member above the surface while supporting the cross member against rotation with respect to the surface. Methods are also disclosed for extracting surface components above a surface.
