Abstract

An elevator is a type of vertical transportation that transports passengers or freight from one level to another in a tall building. The majority of existing lifts and elevators are powered by electric motors and supported by a counterweight connected by a series of cables and pulleys. Having an elevator can be life-changing for many people, especially for those with mobility issues which can assist them to move from one level to another with ease. However, elevators are still unavailable in some high rise buildings due to the high cost of it, which makes the wheelchair users face difficulties in moving between floors. This study is for designing and developing a manual hand pedaling elevator for wheelchair users, which will allow the users to easily elevate themselves to a higher level The invention accomplishes this through a mechanical mechanism of the compiling between compound gears and pulleys without using any external energy or motor, designed to provide fast performance and easier movement with extreme stability. This paper presents an overview of elevators and provides the mechanism analysis of each design. The report includes the selection of the best possible design for the wheelchair user based on several analyzed designs. The analysis was done with ANSYS and manual calculation to achieve the best results of the static and dynamic analyses.
