The present invention proposes a wheel-alternate stair climbing cart which at least has one row of wheels (has two or more rows of wheels best). Each row comprises a plurality of wheels. Two adjacent groups of wheels are intersected. The total length formed by connecting axle centers of a plurality of wheels can at least cross a vertex of three steps. The wheels on the stair at least keep contact with a vertex of two steps. The present invention better solves the problem that a traditional cart is blocked when operating on the stair or is bumpy when moving, and has the advantages of strong weight loading capability, difficult wear and low manufacturing cost.
