Next, we placed the prepared thin hydraulic jacks at the bottom of the building, and controlled the synchronous lifting of all jacks through the hydraulic synchronous lifting system. Here, the latest synchronous lifting technology is used to avoid the previous asynchronous shortcomings. No damage to buildings. After repeated lifting up, the building reached the predetermined height, we placed 2 rows of hydraulic flatbed trailers at the bottom of the building and waited for the evacuation of the jacks. The final trailer needs to be able to fully carry the weight of the building. The project is only half completed here. Next, the old building is towed to its destination, returned to its place, and the hydraulic jack is controlled by the synchronous lifting system again. The difference this time is to use the synchronous descent of the hydraulic jack to make it sit smoothly.
