![]() ![]() 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. Fernando Ortenzi, in Hybrid Technologies for Power Generation, 2022 8 Electrification with flexible hybridization strategies for construction machines – Two-speed power head: drilling and pullback at low speed to ensure a smoothconstruction unload drill pipe from no-load, the power head can accelerate the slide,reducing the auxiliary time and improve efficiency.- Steel Track: can be adapted to a variety of muddy road.- Floating vice: The company”s floating vise patented technology, can effectively extend the service life of drill pipe.- Rotating desk: to increase operator field of view, reducing operator fatigue and makes the operation more simple and comfortable rig.Luca Pugi. Main components, partsused well-known brand, good performance, stable quality, machine use and reliability.The technical characteristics- Powerful:The 194kW diesel engine CUMMINS with turbo torque characteristics, to ensure that rig in a variety of complex geological conditions, the completion of pipe laying operations. Machine Horizontal Directional Drills XZ450-Compact, beautiful appearance, the main technicalperformance parameters reached the domestic advanced level. You also can choose 97kw Euro lll A emission engine which is more environmental oriented and more efficient for your machine. To meet demands of different customers, devices like automatic (semi-automatic) assembly and disassembly device of drill stem, automatic anchor system, driving cab, cold and warm air-conditioner, cold start, frost-proof of slurry, cleaning of slurry and slurry throtting can be added to the maine. ![]() ![]() High-power engine system has sufficient power consumption making it available at various working conditions Ĭlassic H-carling structure, high quality rubber track and W-outrigger are used to form a stable chassis, providing a strong security for the stability of the machine High speed push-pull system and variable motor make it easier for power head push-pull change speed and increase the adaptablity of the drill, improving the efficiency tremendously Besides, power head floating and vice floating patent protect the thread of the drill stem, extending its service life greatly Gear rack push-pull structure offers a stable operation and a reliable transmission of power head. First-class hydraulic components offer a stable hydraulic system to the whole device Hydraulic pilot control ensures strong maneuverability and flexibility. With first-class brands, our major components such as hydraulic system, power system and travel system enjoy excellent performance and stability. It is equipped with hydraulic pilot control, high-speed gear rack push-pull structure with main parameters of which are ranking among the best of the world. XZ200 horizontal directional drill features a perfect combination of exquisite structure, excellent performance and multiple functions. ![]()
