Abstract (en)

[origin: EP2058270A1] The device (H) has a magnetic shift valve (30) arranged in a hydraulic servo line (21'). The magnetic control valve is shiftable between a passage position and a blocking position, where a magnet (31) of the magnetic shift valve is connected to an automatic or manual selecting device (33, 34). The automatic or manual selecting device shifts the magnet of the magnetic shift valve with or without current supply depending on a detection of a low load condition or a high load condition of a main consumer (V) i.e. lifting cylinder.
