Fabricating And Analyzing The Pressure and Rpm Performance of Hydraulic Swing Components on A Mini Excavator Trainer

Abstract

A learning method is very important to achieve existing curriculum standards. For success in the learning process, media or teaching aids are needed that can enhance the learning process and outcomes relating to students' level of thinking (Suwardi et al, 2014). Mini excavator teaching aids are one solution to help become a learning medium for hydraulic systems. Making hydraulic swing components is used to perfect components in mini excavator teaching aids which will later be developed as teaching aids for hydraulic drive systems. The final objective of this research is to manufacture hydraulic swing components that will be installed on mini excavator props and the last is to determine the pressure and rpm performance of the hydraulic swing components. Based on research that has been carried out, to operate a mini excavator prop requires a dimensional radius or distance from the center point with a warning line of 3 m² and the maximum pressure on the mini excavator prop is 150 kgf/cm² which produces 11.17 rpm while the pressure permitted for operating the hydraulic swing component on the mini excavator prop is 100 kgf/cm² which produces 8.54 rpm.
