With electrohydraulic axes, the physical advantages of hydraulics such as compact design, high force density and wear resistance are extended by simple installation and good energy efficiency as well as control via software.
They have become established with various manufacturers in recent years.
However, the available electrohydraulic compact axes are mainly suitable for automation tasks or use in machine tools due to their limited rated power.
In contrast, the HungerDrive developed by Hunger Hydraulik starts at a nominal force of 2,500 kN, whereby - true to the motto: #howbigdoyouwantit - even much higher nominal loads can be considered.
