An actuation system having a table, a lifting column for raising and lowering the table, first and second actuators pivotally mounted to a top section of the lifting column. The first and second actuators are coupled to a first end of the table. A guide plate having a top portion and at least one track is provided. The at least one track is slidingly engaged with at least one guide, the at least one guide is vertically mounted to a third side of the lifting column. The top portion of the guide plate is vertically driven by the third actuator and is universally coupled to a second end of the table.
