There is another way
Bucher Hydraulics has set itself the objective of combining the best of both worlds, electric drive technology and hydraulics, in order to satisfy the increasingly stringent demands of politics and legislation to conserve as much energy as possible. The direct AX drive technology without valves brings hydraulics into new dimensions as a drive force. This technology combines the high force and power density of hydraulics with precision and energy efficiency of the electric drive technology.
“Hic Rhodus – hic salta” as the Romans said, “Prove what you can do, here and now!” Thus, Bucher Hydraulics drive and hydraulic experts quickly converted a test bench into an inverted pendulum. They put a lot of weight on it: 1.2 tons. This weight is not only made to oscillate by the AX-driven linear axis, but is also balanced in the vertical for hours in continuous operation without cooling, as the following video impressively shows:
