Getting a heavy object up a flight of stairs usually requires a team of two or more people. Even with a team of people, the task is often still difficult, dangerous, and possibly insurmountable by one person. This problem is especially prevalent in for those who are moving into apartment complexes. Most apartment complexes have many buildings with two or more floors of living quarters, and elevators are often missing. This project sought to offer a solution to this problem. The solution in question; a motorized hand-truck with 2, trigonal planar pinwheels in place of the stock wheels. The stock wheels were removed. Pillow block bearings were put in their place. These pillow block bearings are the mount for an axle shared by the two trigonal planar pinwheels. Power from a modified winch is supplied to the shared axle by way of chain drive. The two trigonal planar pinwheels also have two “foot wheels” on either side of the end of each respective arm. The “foot wheels” are such that the hand-truck can be rolled around as a normal hand-truck while on flat ground. This project was predicted to be capable of carrying heavy loads of 60-150 lbs. In testing, the final product was shown to be capable of carrying 160 lbs.
