The article introduces a patented design of a liftgate with a screw drive, enabling energy recovery during operation. The proposed solution is an alternative to conventional hydraulic systems, which are characterized by high energy intensity and lack of option for recuperation. A key element of the concept is the integration of the lifting mechanism with an energy recovery system, to reduce electricity consumption and power selected on-board systems. The paper compares energy and environmental efficiency of a traditional hydraulic liftgate and the new screw solution, on the basis of the life cycle analysis (LCA) and dynamic simulations in the MS ADAMS environment. The results show significant reductions in energy consumption and CO₂ emissions, confirming the potential of this technology to decarbonize urban logistics and road transportation.

摘要

The article introduces a patented design of a liftgate with a screw drive, enabling energy recovery during operation. The proposed solution is an alternative to conventional hydraulic systems, which are characterized by high energy intensity and lack of option for recuperation. A key element of the concept is the integration of the lifting mechanism with an energy recovery system, to reduce electricity consumption and power selected on-board systems. The paper compares energy and environmental efficiency of a traditional hydraulic liftgate and the new screw solution, on the basis of the life cycle analysis (LCA) and dynamic simulations in the MS ADAMS environment. The results show significant reductions in energy consumption and CO₂ emissions, confirming the potential of this technology to decarbonize urban logistics and road transportation.
