Discover the benefits of hydraulic jacks
Hydraulic jacks operate by using incompressible fluid, such as oil, pushed into a cylinder by a plunger. When the fluid is pushed into a chamber, it creates pressure and the lift rises. When the fluid is discharged, the lift lowers with the relief of that pressure. Most hydraulic jacks use oil as the fluid because it is stable and provides lubrication.
A hydraulic jack requires fluid, so it's less portable than a traditional scissor jack, and is typically installed in a shop or a garage. When it comes to jacking up an automobile, it's important to always consider safety first, and pay attention to the ground conditions with which you're supporting the jack.
Hydraulic Floor Jacks
Most professional automotive workers will rely on a hydraulic floor jack to help them maneuver vehicles around the shop. However, every floor jack is designed with a particular weight load in mind, so make sure that the one you choose can support the weight you need. Many hydraulic floor jacks are rated to lift up to 20 tons.
Professionals prefer a hydraulic floor jack simply because it will provide more lift power than a hand or crank jack, or even an air jack. These jacks are also known to be stable and secure, which can make checking out the undercarriage of your car just a little less stressful. Many hydraulic jacks and lifts use hydraulic brakes to ensure stability.
A hydraulic lift, sometimes called a hydraulic hoist, is another automotive professional favorite. Hoists are best for larger loads and can typically outperform even a hydraulic jack in the lifting department. Many people have started replacing their air-driven hoists with hydraulic lifts. While a hydraulic lift is typically installed in an automotive shop, you can also purchase portable models, equipped with wheels, so that you can take your hoist with you.
The only problem with using a hydraulic lift is that you have to equip your shop with all the proper lines of a hydraulic system, in order to store the fluid and run it to the lift.
