According to the invention, two driving motors are used in the vertically adjustable jack in order to increase the hoisting power of a nursing bed and be able to lift heavy patients. The two driving motors are mounted as to mechanically operate in parallel. In order to obtain a symmetric load distribution among the two motors, the motors are electrically connected in series and are supplied from a joint voltage source as a serial connection.

Pour améliorer la capacité de levage d'un lit de soins et pouvoir lever des patients lourds, le dispositif de levage réglable en hauteur comporte deux moteurs d'entraînement. Les deux moteurs d'entraînement sont montés de manière à agir parallèlement de façon mécanique. Pour obtenir une répartition de charge symétrique des deux moteurs, ceux-ci sont montés en série et sont alimentés en tant que montage en série au moyen d'une source de tension commune.
