At least one trunnion shaft of a tiltable metallurgical vessel has a driven gear affixed thereto. A gear housing surrounds the driven gear and is journaled on the shaft. Several hydraulic motors are mounted on the gear housing. Pinions on the respective motor shafts engage directly with the driven gear. Rotation of the gear housing, due to reaction between the pinions and gear, is resisted with a torsion bar.
