An industrial truck comprises a lift frame having a load part for carrying a load and a hydraulic system including at least one hydraulic cylinder having a piston rod disposed within a cylindrical housing, and a hydraulic power unit. At least one sensor is configured to determine at least one of: (i) an actual speed of the piston rod of the at least one hydraulic cylinder, and (ii) an actual acceleration of the piston rod of the at least one hydraulic cylinder. Furthermore, a control unit is configured to: (i) receive at least one of a target speed of the piston rod and a target acceleration of the piston rod, (ii) determine at least one of a speed control deviation value from the target speed, and an acceleration control deviation value from the target acceleration, and, (iii) regulate at least one of the actual speed of the piston rod based on the actual speed control deviation value and the actual acceleration of the piston rod based on the actual acceleration control deviation value.
