An apparatus comprising a pair of telescoping arms pivotally coupled between a base and a platform. Each arm comprises a base portion pivotally coupled to the base to pivot about a base pivot axis, an extension portion slidably coupled to the base portion and pivotally coupled to the platform to pivot about a platform pivot axis, and, a pivot support assembly attached along a side of one arm of the pair facing toward the other arm of the pair. The pivot support assembly is configured to allow longitudinal travel of a pivot anchor with respect to the base portion. The pivot assembly is coupled between the pivot anchors. The drive assembly is connected to controllably move the extension portions inwardly and outwardly with respect to the corresponding base portions, and controllably move the pivot anchors toward and away from the corresponding base pivot axes.
