Safety lifting device

A safety lifting device positioning a labelling unit in a vertical direction (Z) in relation to a flow of objects where the labelling unit is arranged for printing labels and/or applying labels to the objects,

• characterized in that the lifting device comprises a linear actuator, a balancing unit, a drive unit connected to the linear actuator, and a movable section, where the labelling unit is connected to the movable section;
• wherein the linear actuator is connected to the movable section and arranged to control the position of the labelling unit in the vertical direction (Z) in relation to the flow of objects through displacing the movable section (8) in an upwards direction (DU) and/or a downwards direction (DD) to a labelling position (PL) of the labelling unit, where in the labelling position (PL) the labels are printed and/or applied to the objects;
• and
• wherein the balancing unit is connected to the movable section and arranged to interact with and support the linear actuator and counterbalancing the gravitational force (FG) exerted on the linear actuator by the labelling unit and the movable section, preventing high loads on the linear actuator,
• wherein the movable section of the lifting device comprises an upper stand unit, and the lifting device further comprises a stationary lower stand unit arranged on a support surface, wherein the upper stand unit is movably arranged in relation to the lower stand unit in the vertical direction (Z), and wherein the labelling unit is attached to the movable section,
• and wherein the linear actuator and the balancing unit are arranged inside the lower stand unit and the upper stand unit.
