Project description:The scientific innovation in this project lies in the combination of the development of a modular design with simultaneous structural optimization aimed at lightweight construction. The combination with a modular design, which serves to partially automate and simplify production, restricts structural optimization due to the strong and ever-changing boundary conditions (e.g. chassis geometry, position of the vehicle units, number of axles and positioning of the crane). The scientific task here is therefore to find a structural optimum, despite the limited variety, which on the one hand leads to the desired significant weight reduction and at the same time, for a given vehicle variety, ensures a low number of frame modules to be provided by the manufacturer.
The main ecological objective of the project is to reduce fuel consumption and thus pollutant emissions in relation to the payload quantities transported, measured in tons. This will be achieved as follows:
A weight-optimized structure of the subframe on the truck for the necessary load distribution and support of the truck-mounted crane, taking into account a new modular energy, time and cost-saving design
A resulting increased payload with full utilization of the permissible total vehicle weight
As a result, a reduction in the number of delivery tours from the depot to construction sites, leading to lower overall energy consumption per transported ton and reducing delivery traffic, especially in the highly congested inner cities
Secondary ecological goals include the aforementioned reduction in traffic load generated by delivery traffic for construction sites, rapid dissemination of this energy-saving and environmentally friendly technology due to its attractiveness for customers through an increase in payload, reduction in delivery tours, and faster as well as cost-saving production.
