Mobility of physically handicapped people is a concerning social issue nowadays and various hand driven tricycle, wheelchair, retrofitted vehicles etc. It’s commonly available in the market for as a handicapped people mode of Transportation. A conventional tricycle for handicapped people is requiring a lot of human effort to operate. An existing model is generally come with separate arrangements for providing motion and giving direction to the vehicle. The basic tricycle is design as on one side chain drive is installed which will be driven manually by rotary mechanism and seat provided at the center for sitting arrangement. A person uses only one hand to steer the handle and other hand is used to rotate the pedal. Using the advantage of leverage, with proper balance and distribution of mass and center of gravity to crank the wheel shaft for propelling. As he can use both the hands on the steering, better control of the vehicle is ensured. The purpose of this paper is to design and fabricate a low-cost tricycle for the handicap people to be propelled by crank lever mechanism attached to the steering column. Push and pull motion of the steering result in forward and backward motion of the chair, while rotational motion of the same gives direction to the chair. As the result a person can use both the hands on the steering for the better control of the vehicle.
