Design and Fabrication of Portable Luggage Cart

Abstract

Luggage is an intrinsic part of travelling. If it is heavy, carrying luggage is a difficult task for anyone. There are many inventions made to resolve this issue. People use various trolley bags to carry luggage. But the price of trolley bags are little higher and cannot be afford by everyone. A portable luggage cart is the best solution to this problem. It is simple and can carry up to 150 kg. It is designed in such a manner that it can be placed in a bag. When it is unfolded the size becomes double. The present work concentrates on design of portable luggage cart and fabrication of the same. Four caster wheels are provided to increase the stability of cart. The cart is designed in CATIA and later equivalent stress and total deformation of design are calculated by using ANSYS. A prototype of the design was produced by using additive manufacturing technique. A STRATASYS 3D printer [FDM (Fusion Deposition Modeling) based)] is used to prepare prototype. Aluminum bars are used to prepare actual cart due to its low density. The final cart is fabricated by using basic mechanical operations like cutting, slotting, fitting and broaching. These carts will reduce the congestion in railway stations and bus stations by increasing the speed of movement of passengers.
