Abstract

A method includes following steps. A washer and a nut are removed from a threaded rod of an expansion bolt that is secured to a drilled hole. After removing the washer and the nut, foot of a semiconductor processing apparatus is removed from the threaded rod. The washer and the nut are placed back to the threaded rod of the expansion bolt. A lifting fork of a bolt lifter is moved such that fingers of the lifting fork are located directly below the washer. The lifting fork is lifted, by using a hydraulic cylinder, to extract the washer, the nut, and the threaded rod of the expansion bolt away from the drilled hole.
