Abstract— In this paper a mechanism is designed for the desired performance output of the machine and these mechanisms are being used in case of climbing wheels. In cities the buildings are generally three or four storied and it is not convenient and also financially not easy to fit electric lifts everywhere. A four bar lift can be used by old or disabled person to climb one floor as subjected to lift. Hence a four bar mechanism to be implemented on every wheel to make the frame to be moved and to make synthesis and simulation for same mechanism to track its actual path and to understand its motion of stair of height of 220 mm. Taking into consideration the available dimensions of the four links a software is prepared with help of Fraudenstein’s equation being compared graphically with existing dimensions so as to calculate the actual deviation graphically and programmatically. Also the sensitivity of each link being carried out for variation of +1 mm and –1 mm in actual dimensions available.
