Auto Body Jack Tools
If you own a vehicle, you also better own a car jack to use in the event of a tire blow-out, a flat tire or another emergency. Besides the jack that comes with your car, there are many other great car jacks and auto body jack tools on the market today.
Trolley Floor Jacks
Trolley floor jacks are close to the ground so they can get under low loads, and they are usually operated with hydraulics. A good floor jack should have a reinforced lift arm for added strength and strong side plates. Some trolley floor jacks operate in a two-stage lift or have dual pump pistons for a quicker rise. Bypass and overload valves in case of an emergency are recommended. The wheels should run on bearings and the rear wheels should swivel for easy positioning of the jack. Among the wide selection of trolley floor jacks you can find low-profile garage jacks and other professional jacks, long-frame jacks, jacks with an adjustable saddle and more. Many trolley floor jacks are easily collapsible for convenient storage.
Trail Jacks
Trail jacks are a necessity for off-road vehicles. They jack straight up in a line and can go much higher than a conventional jack. Trail jacks have an extra large base so they can stand securely on any terrain. The long handle can come separately or attached to the base. A trail jack should be lightweight and easy to maneuver, but should be able to hold up to 7,000 pounds. It should be made of hard steel. Some trail jacks have a top winch-clamp-spreader attachment, which makes the jack a more versatile tool. Such trail jacks dont only lift the car, they can also push, pull and clamp and act as a winch. Another, more unusual trail jack is an inflatable jack that gets hooked to the vehicles tailpipe. The engine is started and the jack inflates. It raises the car quickly and has a lifting capacity of up to 8,800 pounds. And it gives excellent performance in any terrain.
Bottle Jacks
Bottle jacks are hydraulic jacks that look a little like a bottle. They are placed in a horizontal position. A long lever lifts a main arm on a bottle jack and provides more lift per stroke than you can get with a conventional jack. They can lift just about anything and are standard equipment for search-and-rescue teams because its possible to place them in tight spots. They provide good leverage wherever they are placed.
Other Jacks
The most common car jacks are scissor jacks, which unfold similar to a pair of scissors when jacking up a car. They are compact, have a removable handle and are found in most cars today. Cylindrical jacks can handle from 5 tons to more than 1,000 tons weight, so theyre perfect for large vehicles. They often come with an internal spring that helps close the jack when the pressure is released. Air-powered jacks work with compressed air and are preferred in jobs where sparks are a hazard.
