FIELD: transportation.
SUBSTANCE: invention relates to a drive (1) having a master unit (3) and a slave unit (19). Slave unit (19) includes a first linear movement node (15), having a first driven member (7) and second linear movement node (16), fluidly coupled through a pipeline system (27) to first linear movement node (15), having a second driven member (8). Master unit (3) is hydraulically connected with a pipeline system (27). To reject slave units (7, 8) by master unit (3), fluid exchange is possible between first linear movement node (15) and second linear movement node (16). First linear movement node (15) and second linear displacement node (16) have prestressing elements (12, 25). In accordance with the invention, these prestressing elements (12, 25) are supported in the opposite direction on a movably mounted clamp (4).
EFFECT: provision of a constant force on the slave node.
