In America, houses that have collapsed are usually lifted with hydraulic machines like this one. This technique is usually used when the foundation of the house is damaged due to ground shifting, subsidence, or the age of the building. A hydraulic device is installed around the excavated foundation. This tool works on the principle of fluid pressure to provide enough lift to lift the house without damaging its structure.#technology #technique #tech #hydraulic #america #house #excavator
