1. A lift comprising:
- a support frame;
a pair of lift arms, each of the lift arms including a first end pivotally coupled to the support frame and a second end opposite the first end, the second ends of the pair of lift arms being configured to engage a motor vehicle tire such that the pair of lift arms cooperatively support the tire; and
a powertrain including a motor and a pair of pull rods, each of the pull rods being coupled between the motor and one of the pair of lift arms, a means for relative movement of the motor with the support frame in a vertical direction and restrained from movement relative to the support frame in horizontal directions;
wherein the powertrain is operable to move the pair of lift arms between a first position, in which the second end of each of the lift arms is positioned a first distance above the support frame, and a second position, in which the second end of each of the lift arms is positioned a second distance above the support frame, the second distance being greater than the first distance.

Abstract
In at least one illustrative embodiment, a lift may comprise a support frame, a pair of lift arms pivotally coupled to the support frame and configured to support a motor vehicle tire, and a powertrain including a motor and a pair of pull rods, each of the pull rods being coupled between the motor and one of the pair of lift arms. The powertrain is operable to move the pair of lift arms between a first position, in which the second end of each of the lift arms is positioned a first distance above the support frame, and a second position, in which the second end of each of the lift arms is positioned a second distance above the support frame, the second distance being greater than the first distance.

12. A lift comprising:
-
a support frame including a pedestal; a pair of lift arms, each of the lift arms including a first end pivotally coupled to the support frame and a second end opposite the first end, the second ends of the pair of lift arms being configured to engage a motor vehicle tire such that the pair of lift arms cooperatively support the tire; a powertrain supported on the pedestal and operable to move the pair of lift arms between a first position, in which the second end of each of the lift arms is positioned a first distance above the support frame, and a second position, in which the second end of each of the lift arms is positioned a second distance above the support frame, the second distance being greater than the first distance; and a means for relative movement of the powertrain to the pedestal in a vertical direction when the pair of lift arms moves between the first and second positions. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
