4. Hydraulic 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.

5.  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.

9.  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.

10.  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.

11.  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.

12.  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.

14.  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.

15.  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.

16.  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.

17. Thus 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.
