ABSTRACT:
A mixing bowl lift apparatus and method for lifting a mixing bowl above a work table and partially inverting the mixing bowl to empty the contents thereof on the work table. The lift apparatus includes a lift framework having a pair of spaced lift arms extending outwardly from the lift framework at an obtuse angle. The lift framework is pivotally coupled between a pair of upright columns that are secured to a base plate bolted to the floor beneath the edge of the work table. The lift arms are configured with a C-shaped cross section so as to securely receive the circumferential, raised ridge on the mixing bowl. An electrically driven piston raises and lowers the lift arm assembly. The obtuse angle between the lift arms and the lift framework allows the lift arms to be raised beyond the vertical axis and thereby partially invert the mixing bowl above the work table. A linkage coupled to the electrically driven piston is operable to hold the electrically driven piston at a first position where it will raise and lower the lift arm assembly and at a second position where it will hold the lift arm assembly in a stowage position below the edge of the work table.
