A mechanical jack is a device which lifts heavy equipment. The most common form is a car jack, floor jack or garage jack which lifts vehicles so that maintenance can be performed. Car jacks usually use mechanical advantage to allow a human to lift a vehicle by manual force alone. More powerful jacks use hydraulic power to provide more lift over greater distances. Mechanical jacks are usually rated for a maximum lifting capacity (for example, 1.5 tons or 3 tons). The jack shown at the right is made for a modern vehicle and the notch fits into a hard point on a unibody. Earlier versions have a platform to lift on the vehicles’ frame or axle.

A lifting jack is an important tool when you are doing an extensive home remodeling project. When you are involved in any type of heavy lifting, like leveling off a basement, or holding up a porch, a lifting jack is invaluable.

Often times called a scissor lift jack, a lifting jack is something that you will need when you are thinking about digging around your home, or making major improvements. Mostly used for holding up a home off the ground while a foundation is dug, or a crawlspace is improved, a lifting jack is also used for several other applications. But, how do you use one? Here is a complete listing of how you should use your lifting jack.
