There are three types of floor jacks: for repairing foundations, supporting main joists, and lifting heavy vehicles. Automotive jacks use hydraulic systems and are rated for different weights. They are used for quick tire changes and undercarriage checks in auto repair shops and racing.
There are three different types of floor jacks. Two are used in homes and businesses, while the other is used in auto repair shops. Although the name is the same, each type is used in completely different ways.
When floor joists are sagging or foundation walls are crumbling in a house, a floor jack is used to support a house to replace foundation walls or to support floors while replacement joists are added to the original frame. Once the foundation is repaired or replaced, the house is gently lowered and secured to the new foundation.
If the foundation of the house is in good shape, there is also a type of floor jack that is basically a solid metal post with a flat end. The flat end sits under the main house beam and snaps firmly into place. This solid post helps support the main joists and prevents sagging. Without proper care, sagging or rotting floor joists will eventually collapse.
Another type of connector that goes by this name is used for telephone and cable adapters. Contains either the phone jack or data jack port and can be sunk into the floor or baseboard mounted where the floor and wall meet. This jack is usually pre-wired so it only needs to be connected to existing phone or data wiring inside the house and then mounted in place.
An automotive floor jack uses hydraulic systems to raise and lower heavy vehicles, typically personal cars and trucks. Lays flat on the ground during use. Each automotive jack is rated for different weights, generally in the range of 2 to 20 tons (1,814 to 18,143 kg). The hydraulic lifting system can be used to easily lift heavy vehicles by simply pumping the long arm that extends from the jack body. In this way, the jack allows the mechanic to change tires or remove them to check brake systems, examine undercarriage damage, or check exhaust pipes, among other applications.
In most cases, a hydraulic lift is used instead of a jack when it comes to auto repair shops. However, for quick tire changes and undercarriage checks, a floor jack is the best tool. Also, it is commonly used in racing to lift each side of the car for quick tire changes.
