Introduction 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.
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.
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.
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.
Conclusion • 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.
