Driven guide systems for lifts

A lift comprising:

• a base;
• a platform;
• two pairs of telescoping arms pivotally coupled between the base and the platform, each arm of each pair comprising:
• 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 configured to allow longitudinal travel of a pivot anchor with respect to the base portion;
• two pivot assemblies, each pivot assembly coupled between the pivot anchors of one of the pairs of telescoping arms;
• and
• a drive assembly 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.
