DESIGN OF 2TONNES AUTOMATED HYDRAULIC JACK

ABSTRACT

The design of 2 tones automated hydraulic jack was carried out using the basic principles of machine design and analysis. The hydraulic jack was designed with a 204watts wiper motor with the output lever having a torque of 30Nm.  The effective diameters of ram and plunger pistons were found to be 12mm and 6mm respectively, when the load lifted was 2000N with mechanical advantage being 3.4. The working stress was 21MPa when the effort applied at the handle by the lever was 594.3N. Output of the machine was 240Nm with the critical buckling load being 156969.26N. A current of 100mA and a constant amplitude voltage of 0.6V were maintained through the light emitting diode, LED.   

Keywords: hydraulic jack, wiper motor, lever, torque, ram and plunger pistons, load, mechanical advantage, working stress, critical buckling load, current and voltage.
