IntroductionHydraulic lift is a type of machine
that uses a hydraulic cylinder to lift and lower objects by applying relatively small force compared to the weight of the object to be lifted.
It’s working is based on Pascal’s
Law.
Objective To fabricate a hydraulic lift with the
help of hydraulic jack at commercially low cost.
To raise or lower platforms to work on heavy components such as engines.
To place the work material on ergonomically comfortable access points.

Bill of Materials
Fabrication Hollow metal rods of (1X1) inches
cross-section is selected. They are cut into required lengths
and welded together by arc welding to form bottom and top metal frames and also the cross-links.
Continued.. Then the metal plates of required
length are welded to the top and bottom metal frames.
The rolling wheels are welded at the end of the cross-links by some supports.
Continued.. The cross-links are then connected to
the metal frames by means of Half Threaded Bolt and Nuts.
Then the hydraulic jack is placed at the bottom metal frame by connecting its stroke to the cross-link.
Working of Hydraulic Lift The hydraulic jack is manually
pumped to raise the hydraulic lift. Ensure that the pressure relief valve is closed tightly.
The pressure relief valve at the bottom of the hydraulic jack is
opened gradually to lower the lift.
Cost Estimation
Advantages Hydraulic table lifts are so simple to
operate and move and they eliminate repetitive strain injury (RSI)
When not in use and fully retracted hydraulic table lift take up little space in a warehouse or office.
Applications Heavy weights of 100 kg can be lifted
easily to a height of 2 feet by this hydraulic lift.
In workshops heavy components such as engines can be lifted to required height so that we can work on it conveniently.
It can be used as bike lift by altering its
size.
Future Scope The height of the lift can be
increased by increasing the stroke length (or) by adding additional zig-zag links.
The hydraulic lift can be designed for high load by using a suitable high capacity hydraulic cylinder.
ConclusionThus a Hydraulic lift to raise 100
kg of weight up to a height of 2 feet is designed and fabricated at a commercially low cost.
It is recommended for the engineering industry and for
commercial production.
