Analysis of disability lifter design utilizing hydraulic lifter

Abstract

Persons with disabilities describe the prolonged condition of a person who experiences physical, intellectual, mental, and sensory limitations, experiencing particular difficulties in participating fully and effectively with other people based on equal rights. Mobility has been currently higher, enabling the higher desire to explore certain places. This necessity is also suffered by people with disabilities, expecting a specific device for daily assistance such as getting into the car easily and without needing much help from others. Thus, it is necessary to design a specific tool to help people with disabilities, acknowledged as the Disability Lifter, installed on cars that have an L-type hinge. The design of this Disability Lifter employs a hydraulic lifter with a Tiandi TDDL-20 type motor. Based on the design result, the motor power is 0.109 kW with a pressure of 15.69 Bar. The safety factor value of 2.25 indicates that this Disability Lifter has strong resistance and is safe to use.
