The key difference is all in the construction. So, a hand truck typically rests on two wheels and is partially guided by hand with a grip or handles toward the top. A dolly is usually a flat platform perched on a set of four wheels, with a push handle behind. You’ll notice that many of our top picks are convertible models that can switch between the different designs based on what you’re moving. Dollies can typically carry a lot more weight and are good for moving the heaviest objects. However, hand trucks are better at maneuvering and controlling more awkwardly-shaped objects. They both have their uses.
