KEWAZO develops a robotic system for on-site construction logistics. The initial application area is scaffolding. The KEWAZO logistic system provides a cost-efficient and safe transportation of scaffolding parts during assembly. In comparison with existing solutions - construction lifts and rope hoists - the system operates with just two workers and transports parts not only vertically but also horizontally. The solution addresses the problem of labor shortage, saves labor costs by 30% and accelerates the assembly speed by 42%. In construction, the robotic system can be also applied within other construction trades. The solution can be used for logistic purposes in other industries, particularly for warehouse logistics.
