ABSTRACT:
A hydrostatic drive (1) with a hydraulic pump (3) and a plurality of hydraulic motors (6-9) that are hydraulically linked with the hydraulic pump (3). One speed sensor (20; 21; 22; 23) each allocated to a respective hydraulic motor (6; 7; 8; 9) and is linked with a control device (24) and detects the speed (n1; n2; n3; n4) of the allocated hydraulic motor (6; 7; 8; 9). Every hydraulic motor (6; 7; 8; 9) is functionally linked with a brake device (26; 27; 28; 29) that in turn is linked with the control device (24). When the speed (n1; n2; n3; n4) of one of the hydraulic motors (6; 7; 8; 9) exceeds a predetermined threshold value (ng), the control device (24) triggers the brake device (26; 27; 28; 29) allocated to the associated hydraulic motor (6; 7; 8; 9).
