For a newly developed roller loader, a complete powerpack was developed and delivered as a prototype. Only the installation space and the hydraulic power capacity were specified by the customer. First, a 3D model with all components was created with AUTODESK INVENTOR®. The restricted space offer led to the development of special valve blocks and connectors. In designreviews with the customer the model was further developed and finally built and supplied as a built-in, painted prototype of Ingessta.
