Hydraulic Floor Jack
is an instrument project for lifting and lowering verchicles.Dual steel.Used in Garage or home own car.
When floor joists are sagging or foundation walls are crumbling in a home, a floor jack is used to prop a house up in order to replace the foundation walls or to support the floors while replacement joists are added to the original framework. Once the foundation is repaired or replaced, the house is gently lowered and secured to the new foundation.
If the foundation of the home is in good shape, there is also a type of floor jack that is basically a solid metal pole with a flat end. The flat end is placed under the house抯 main beam and cranked tightly into place. This solid post helps support the main joists and prevent sagging. Without proper attention, sagging or rotting floor joists will eventually collapse.
