ABSTRACT At present people use ladders and long stools to work on a point which is more than their height. In this case one can easily reach the work point, what if he wanted to move the ladder? For this purpose he has to get down and move his ladder every time which consume more time and even increase work burden. For this purpose therefore we intend to design a chair or a platform which is comfortable to work and can be lifted to a certain point and can be moved in horizontal direction. Basically the Portable Extendable Chair is equipment which is served for lifting vertically upwards, moving in horizontal direction and it can be rotated 360ô€€€ both in clockwise and anticlockwise directions In the design and fabrication of Portable Extendable Chair the Electro-mechanical actuators are used. The Electro-mechanical actuator consists of motor which can drive both in forward and reverse direction, and a Screw attached to its shaft. A nut is welded along the column which makes the screw to rotate and move both up and down.The Portable Extendable Chair has a platform which is designed to be lifted form low to high level using Electro-mechanical actuators. Similarly another Electro-mechanical is used to give horizontal motion to the platform. At the bottom to this platform there is a flywheel gear which is attached to the motor, this gives a rotation movement to the Portable Extendable Chair. The Platform Designed for lifting purpose is comfortable which will easily bear the load. The specifications of motor and screw electro-mechanical actuator can be decided on the basis of applying load and height which is to be lifted. This Portable Lifting Device is designed so that it occupy less space with high comfort factor when compared to other lifting machineries Keyword: Electro-mechanical actuator, wiper motor, fly wheel gear, Screw
