ABSTRACT:
A lift assembly includes four swing arms interconnecting a base member and lift platform. A hydraulic cylinder selectively elevates the lift platform relative to the base member. A stiff leg also extends between the base member and the lift platform and cooperates with a series of stop blocks for locking the lift platform at predetermined heights above the base member. A link is associated with the stiff leg to selectively support the stiff leg above the stop blocks and permit an operator to move the lift platform between the predetermined heights. The link automatically positions the stiff leg for engagement with the stop blocks if the direction of movement of the platform is altered.
