A lifting means includes at least two telescopically displaceable lifting beams (1, 2), of which one (2) is connected to a driving means (3) in order to displace the second lifting beam (1) to and fro within said first lifting beam. A casing (4) can be placed to surround both the lifting beams and rest against these and surrounds both the lifting beams an essential part when they are protruded. A pressure spring (5) is placed within the casing (4) in order to displace the casing (4) so it surrounds both the lifting arms (1, 2) when they are in the protruded position in relation to each other whereby the pressure spring rests against the end of the casing (4), which end surrounds the displaceable lifting arm (1). A support (6) for the second end of the pressure spring (5) is attached on the fixed lifting beam (2).
