DESIGN AND FABRICATION OF LOAD CARRIER TROLLEY

This paper deals with the designing and production of a trolley, which could climb stair. The technical troubles in designing of this trolley are the steadiness and velocity of the automobile at the same time as climbing stairs. However, the steepness of the stairs is likewise the vital concern of this examine. The want for this sort of machine arises from every day requirements in our society. Devices which includes hand trolley s are used for easy lifting of load on flat ground however, these trolleys typically fail when it comes to wearing the weight from ground to ground through stairs. Inside the situation of this, the challenge attempts to layout a stair mountaineering trolley which can bring heavy objects up the steps with less effort as compared to wearing them manually. In our challenge, the trolley is prepared with tri -star wheels which permit us to hold load up and down the stairs. It also eases the movement of trolley in irregular surfaces like holes, bumps, and many others.
