Abstract

See full text

The present invention relates to a scissors lift comprising a bottom frame, a top frame and a scissors mechanism arranged between the bottom frame and the top frame to displace the bottom frame and the top frame relative to each other by transfer of an actuation force. The scissors mechanism comprises a central hollow scissors arm delimited between opposite scissors arm surfaces, wherein the central hollow scissors arm has a bottom pivotal connection connecting it to the bottom frame and a top pivotal connection connecting it to the top frame. Further, the mechanism comprises two passive scissors arms being pivotally connected to the bottom frame and pivotally connected to the top frame. Each of the two passive scissors arms are pivotally connected to the central hollow scissors arm on the opposite scissors arm surfaces of the central hollow scissors arm. Further, the scissors lift comprises a motor providing said actuation force, said motor located between said opposite scissors arm surfaces of said central hollow scissors arm. Thereby, the motor may be protected and at least partially enclosed by the scissors lift and even by the central hollow scissors arm, allowing a safer and/or more easily maintained scissors lift.
