Triple wheel stair climbing carts

Triple wheels

— a wheel block with three small wheels that helps to more easily overcome steps, curbs, and other differences in height. When climbing, one wheel rests on the step, and the entire block rotates further, making it easier to pull the cart up the stairs than a model with regular single wheels. This design is especially useful for utility, foldable, and cargo carts if they are often used in entrances, stores, warehouses, or for deliveries.
