Summary:The drive has drive units (14) e.g. slewing gear drive unit, hoist drive unit, bucket drive unit and arm drive unit, where the slewing gear drive has two reversible adjusting units (E1-E4) e.g. hydraulic adjusting units, which are coupled with a hydraulic accumulator (Spr). The reversible adjusting units are connected with the drive units and reverse the flow directions of the drive units in same rotation direction, so that the adjusting units operate as motor or pump. The hydraulic accumulator compensates the hydraulic oil withdrawn from or fed back to another hydraulic accumulator (Sph). Die vorliegende Erfindung betrifft einen Antrieb für einen Bagger mit einer Reihe von Einzelantrieben, wie einem Drehwerksantrieb (E1,E2), einem Hubantrieb (E3,E4), einem Löffelantrieb (18) und einem Stielantrieb (16), wobei für den Drehwerksantrieb (E1,E2) zwei reversierbare Verstelleinheiten (E1,E2) vorgesehen sind, die zumindest mit einem Energiespeicher (SPR) gekoppelt sind.
