Carrying heavy materials from one place to another is always challenging especially if it involves going up a set of stairs. To eliminate this difficulty, 3-wheel stair trolley will be designed to reduce the amount of work done by a person to carry the load up the staircase. This multifunctional trolley can also be used to get to high places. It is also easy to keep it in storage as it can be folded and will consume less space if u compare it to a normal trolley. The main structure of this trolley is the tri wheels that is connected to a connecting rod which enable us to carry the load up and down the steps and help lessen our energy used. Besides that, it also eases the movement of trolley when going on irregular surfaces such as holes, bumps, etc. This trolley contains 6 wheels, 3 on each side which are set in a triangular pattern. The uppermost wheel rests on the upper step while the other 2 wheels set on the lower step. This allows you to apply leverage as you pull the trolley up the stairs
