Who invented the original concept of the parallelogram lift? OMER! In the late 70s a brilliant engineer by the name of Eride Rossato converted the basic concept of a parallelogram (remember your high school geometry class?) to be used in the context of vehicle lifts.
In geometry, a parallelogram is a quadrilateral with two pairs of parallel sides. In Euclidean geometry, the opposite or facing sides of a parallelogram are of equal length and the opposite angles of a parallelogram are of equal measure.
Basically Mr. Rossato took this concept and applied to lifting both automotive and heavy-duty vehicles. In order to insure that the two runways remained parallel during lifting Mr. Rossato came up with the unique concept of a torsion bar. The torsion bar is a mechanical device that insures co-planarity and is one of the hallmark features of an Omer lift. The torsion bar is simply a mechanical linkage between the legs that connect to the runways and serves as both a mechanical connection and a form of synchronization.
In the late 80s the original concept of Mr. Rossato’s design was copied by others but no one has ever been able to duplicate the torsion bar concept. The Omer torsion bar allows the following benefits:
1) Other competitors make the concrete the anchoring device for the lift and they call this an “open floor design.” This is not altogether the best solution since over 70 anchor bolts have to be drilled in the ground at a depth of 8 inches to insure that the lift stays anchored in the shop floor. Over the years and after continuous hinging the concrete can become cracked. With the torsion bar design this can never happen because the torsion bar and the continuous base (a metal connection between the legs) becomes the anchoring device for the lift.
2) Allows for co-planarity (alignment between the two lifting runways that the vehicle sits on) between the runways.
3) Allows for the lift to be situated over relatively uneven floors and requires no anchoring per se. (In order to avoid shifting of the lift lag bolts [5/8”] are placed on the bottom of the lift to prevent shifting of the lift in surface mount applications.
The original Omer concept contains the following benefits and features:
