A lifting column includes at least five column elements which are at least partly nested, and a first and a second drive arrangement. The first drive arrangement is configured to move the three innermost column elements relative to one another. The second drive arrangement is configured to move the three outermost column elements relative to one another.

Nested lifting columns

A linear actuator, a housing for such a linear actuator, an actuation system, and a method for assembling a linear actuator. The linear actuator has an actuating mechanism and a housing. The actuating mechanism includes a spindle and a nut and it is configured to convert rotational motion into translational motion. The housing has two housing parts and the actuating mechanism is at least partially arranged in the housing. The two housing parts form a plurality of separate cavities that are configured to receive separate components of the linear actuator, in particular of the actuating mechanism.
