Three-wheeled stair climbing carts

Triple wheels

— a wheel assembly consisting of three small wheels that helps to easily overcome steps, curbs, and other height differences. When going up, one wheel rests on the step and the entire assembly rotates further, making it easier to pull the cart up stairs compared to models with regular single wheels. This design is especially useful for utility, folding, and cargo carts if they are frequently used in entrances, stores, warehouses, or for deliveries.
