A lifting device (1) for a metallurgical ladle (2), in which there is liquid metal (3), has two pairs (4) of vertically oriented posts (5) and two horizontally oriented transverse struts (6). The transverse struts (6) are fastened to the posts (5) of a pair (4) of posts (5) each. A transverse beam (7) is provided for each transverse strut (6) and can be positioned in the vertical direction relative to the transverse strut (6) by means of an individual hydraulic cylinder unit (8). A hook (11) for receiving a pin (12) arranged on the metallurgical ladle (2) is suspended from each transverse beam (7). The hydraulic cylinder units (8) each comprise a hydraulic cylinder (9) and a piston (10) that can be retracted and extended relative to the hydraulic cylinder (9). The transverse beams (7) are arranged above the transverse struts (6). The hydraulic cylinder units (8) act in such a way that the transverse beams (7) are moved upwards when the pistons (10) are extended and are moved downwards when the pistons (10) are retracted. The associated treatment device additionally comprises a treatment unit (23) for treating the liquid metal (3), which treatment unit is arranged above the transverse struts (6) of the lifting device (1). The hydraulic cylinder units (8) are designed as servocylinders.
