Abstract (en)
[origin: WO2015139910A1] The invention relates to a hydraulic drive comprising at least one hydraulic machine (11, 12) in a hydraulic system (25), which has a high pressure side (16) and a low pressure side (13). In order to simplify the operation of a hydraulic drive, said hydraulic system (25) comprises a normally open safety valve (30) which, in an open position (Fig 1) allows pressure to be reduced on the high pressure side.
