Tri-wheel trolley with adjustable holder / Muhammad Ekhwan Farhan Edzrizar

The world right now full with mechanical things that we use to doing work at office, outdoor and more. However, there are still changes in process of moving an item or load to higher place compilation using stairs. The first solution for this like elevators that can transfer load to the from ground to high place, however the facilities of elevators is not available. Like example, school, construction side, colleagues and so on. In this project target is to create a mechanism that can use to transfer load thru stairs either going down or up. As example, hand trolley that human can use to transfer the load but it has their fails, such as trolley usually can’t transfer the load thru stairs because the structure of wheel of hand trolley that just suitable for flat ground and the holder of hand trolley can’t adjust to place we wanted to place. So this project target to create trolley in upgrade structure that can lift heavy load, can adjust the holder and most important is can use thru the stairs. The main objective of this project is to make the trolley in user-friendly so the movement will smooth and can carry heavy load while climb the stairs. In this project we will use dynamic method for the movement of trolley, strength and static method to know how strong the structure of trolley. The trolley will be the best because two things will upgrade and more effective in real life.
