Design and manufacturing of six wheel Staircase trolley

Abstract

This article deals with the designing and manufacturing of a trolley, which can climb stair or move along very rough surface. The technical issues in designing of this trolley are the stability and speed of the trolley while climbing stairs. However, the steepness of the stairs is also the important concern of this study. The uses of this special trolley are in the frequent lift of goods such as books for library, medicines for hospital, regular mails for any institutes, or transportation any toxic material for industries and give freedom to the retarded person or paralyzed patients to move anywhere over flat surface as well as stairs. Using of this vehicle, the labor cost can be reduced as well as huge amount of loads can be transferred uniformly with less power consumption.
