description: The subject of the work is a hand truck for lifting loads upstairs. The purpose of the work is the design of a trolley for lifting loads upstairs. Research method: structural analysis, option selection, design in Creo, stress state check in Ansys. In the course of the work performed, information about handcarts was collected and studied. The analysis of the ladder trolleys used for lifting small-sized loads was carried out. After comparing all types of ladder trolleys, a hybrid crawler trolley without a drive was selected as the most suitable according to the stated requirements. Calculations of the main components of the trolley for strength were made. As a result of the calculations, it was decided to optimize the design of the platform and change the material used in order to improve the strength characteristics. At the conclusion of the work, an assessment was made of the convenience of using the trolley when lifting loads, and also the effort that a person should make to lift the trolley up the stairs was found.
