What kind of jack is needed to lift a wooden house.

– People often ask how to lift a wooden house with jacks with their own hands so that it does not fall apart. There is only one piece of advice – you need to understand where the vector of applied forces is directed. The building can be lifted both clockwise and vice versa. We make 3-10 circles (as many as needed) until the house rises to a sufficient height. I do not recommend lifting it more than 350 mm, although we lift houses up to 80 cm, and with the use of special technology and up to 1.8 meters. When lifting, it is necessary to avoid rocking the building. This comes with experience – you already feel the moment after which it physician data begin to lose stability.
Experience shows that to lift a frame house weighing up to 7 tons, 1 jack with a force of 10 tons is enough. The house will have to be lifted slowly, gradually moving the jack to different points. The building (one side) can be lifted no more than 3-5 cm at a time, gradually leveling it and working in a circle! In professional work, 15-20 jacks are used at the same time for this operation.
Strong metal plates are placed under the wooden beams of the building. To increase the support area, it is more convenient to support the jack on wooden pads, which allow increasing the support area on the ground.
The horizontality of the lift is controlled visually; it can be leveled using breakaway points, templates (board trimmings), since the laser level is poorly visible during the day.
Stone buildings can also be lifted, but another technology is used, a detailed description of which we will devote one of our next articles. A stone building must be lifted all at once, simultaneously from all sides, otherwise the lift will lead to the destruction of the building.
