Machinery manufacturers often start with the drive train when electrifying their vehicles. The electric motor, power electronics, and a battery system replace the combustion engine, transmission, and tank. The potential for optimizing the working hydraulics is often ignored and the existing hydraulic architecture is taken over from the combustion engine vehicle - with all its disadvantages.
Adapting the working hydraulics to the new requirements opens up new possibilities for the electric vehicle: The higher energy efficiency enables the installation of a smaller battery or a longer range for the vehicle.
Quiet machines enable new application possibilities
Without a diesel engine, the working hydraulics often come to the foreground acoustically. Speed-controlled drives and quiet hydraulic pumps are capable of significantly reducing the noise emissions of electrified working machines. This enables new application possibilities, particularly in noise-sensitive residential areas and at night.
New opportunities to automate processes
Perfectly tuned electrohydraulic controls can be precisely activated and easily integrated into the machine concept. Whether and to what extent it makes sense to invest in modern hydraulics depends on the specific application and the market positioning of the machine manufacturer.
