Next, remove the bolts and nuts connecting the base and the pedestal. Then, use the lifting device to lift the base so that the base is separated from the pedestal. After the base is removed from the pedestal, the base no longer presses against the positioning mechanism. At this time, under the action of the elastic expansion joint, the support can be pushed upward so that the pressing part on the support no longer presses against the locking mechanism. The locking mechanism resets under the elastic force of its own elastic element and no longer locks the bottom beam. At this time, the positioning mechanism and the pedestal can be removed from the top of the tower in sequence using the lifting device. The installation and disassembly steps are simple and save time and effort. Attached Figure Description
