Abstract
A platform lift configured for supporting the movement of items between a floor-level area and an elevated area includes a rigid, floor-level platform with two opposed sides, an above-floor mast arranged at each of the opposed sides of the platform, and a knuckle assembly coupling each mast to its respective side of the platform. The masts together support the platform for movement in a lifting direction normal to the platform, and each include an actuator coupled to its respective side of the platform that is selectively operable to impart lifting movement thereto in the lifting direction. The knuckle assemblies together permit the platform's rotation towards and away from the masts when their respective actuators impart different amounts of lifting movement to the opposed sides of the platform in the lifting direction.
