Hydraulic Floor Jack How It Works

Toe lift hydraulic jacks are a specific type of hydraulic jack that can be used to lift machinery and other loads where the clearance between the ground and the bottom surface of the load is low.

Hydraulic floor jack how it works.

The piston pushes the bottom of the arm forward and the top of the arm rises lifting the saddle and the vehicle with it. In this video we will be going over how the hydraulic t. In this 2 part video i disassemble a bottle jack and show how it works. The hydraulic jack is a very useful device for lifting even heavy cars or other loads with the least effort.

That is the pressure applied to a fluid stored in a container will be distributed equally in all directions. This special type of jack works in situations where a bottle jack or floor jack would not function due to the low ground clearance of the load. They are often used for heavy duty lifting. In a floor jack the bottle jack unit is parallel to the ground and the piston is attached to an arm with special joints.

I started looking at a hydraulic trolley jack and got to thinking it would make a good physics video. How do hydraulic jack works hydraulic jack working is based on pascal s principle. Hydraulic floor jacks are an excellent example of the power of controlled pressurized fluid. Hydraulic floor jacks are composed of different kinds of levers valves and hydraulic pistons in order to lift heavier loads.

Plus you re using a longer handle and you re getting more lift per stroke with the increased leverage allowing you to pressurize more oil and move it around quicker. This category of floor jacks is more complicated compared to mechanical floor jacks. In a floor jack it s the same thing except the bottle jack is positioned horizontally and pushes against a lever lifting the main lift arm. Anyone who has every used this type of jack knows it has a horizontal lift arm that is raised by pumping the handle of the jack.

Quite a few visitors to the site have emailed me asking how does a hydraulic floor jack work so i figured it would be useful to put together this quick short post to help demystify the workings behind hydraulic jacks. Watch all the videos in this how it works series.
