  • Publication number: 20180127011
    Abstract: A wheel-alternate stair climbing cart at least has one row of wheels (preferably two or more rows of wheels). 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.
