A lifting apparatus for an industrial processing station, i.e., a lifting table for conveying a body shell during series production of motor vehicles, wherein the lifting apparatus conveys a workpiece on a top frame moved in a purely vertical direction, where the lifting apparatus has, as first vertical guide, at least one isosceles slider-crank mechanism actuated by a motorized drive element, where the isosceles slider-crank mechanism, which consists of a fixed-bearing swing arm with a swing-arm bearing thereof, a control arm with a control-arm guide, a control-arm central joint and a fixed-bearing joint connected to the top frame, is configured to move via actuation of the tie rod acting on the fixed-bearing swing arm, and where particular use of an isosceles slider-crank mechanism, which is also known literature as a “Scott-Russell mechanism”, provides a simple and effective vertical guide system that allows low overall heights with a minimum production outlay.
