For this reason, it is important to use components that are widely diffused to assure their availability for a long period despite the relatively small number of constructed machines. Modularity and market availability: Proposed machines are constructed in relatively small series, but they have typically a long operational life to be assured. For this reason, thermal stability and reliability of cells is fundamental. Thermal stability: The machine is subjected to harsh environmental and operational conditions in construction yards.
Modular Power Pack and Optional hybridization of proposed system through the connection with an external powerpack. Trenchless excavation is a technique that is often used for a sustainable and cheaper installation of many underground services and commodities that are currently fundamental for urban communities with a limited impact not only in terms of pollution but also of potential waste of time and resources of the involved communities.įig. So, in this case studies it is considered the possibility of an electrification and a hybridization of this kind of vehicles/construction machines.Ĭonsidered case study is a tracked directional drilling machine which is often used to perform trenchless excavation.
These machines are usually equipped with ICE combustion engines that provide power for hydraulic or electro-hydraulic actuations.Īlso, these machines can be considered improperly as heavy vehicles with very specialized and energy demanding onboard functionalities. There is a wide range heavy construction machines that are usually wheeled or tracked to assure their mobility in construction yards and their transportability.
