A motor vehicle lift includes two parallel runways, each provided with at least two elevating devices each having first and second uprights hinged to each other, to the floor (runway) and to the runway (floor) respectively; first and second arms hinged together, the second arm being further hinged to the second upright along a hinging axis equidistant from the axis on which the second upright is hinged to the runway (floor) and from the end of the second arm, which is slidable along a guide provided in the runway (floor), the first arm being also hinged to the first upright; and an actuator device securable selectively to two elements of the quadrilateral formed from the first/second uprights and the first/second arms, at least one of the parts of the quadrilateral being provided with elastic means to vary the dimension between the two hinged ends.

1. A motor vehicle lift comprising: two parallel runways for supporting vehicle wheels, each runway being provided with at least two devices for elevating the vehicle wheels from the floor, wherein each device comprises:a pair of equal-length first (6) and second (10) uprights having an end hinged to each other, and another end hinged to a floor and to the runway respectively, in positions corresponding with two superposed vertical axes,a pair of first (14) and second (16) arms hinged together at one end, the first arm (14) having a length shorter than that one a length of the second arm (16), which is hinged to the second upright (10) along a hinge pin (22) equidistant from an axis (12) on which the second upright (10) is hinged to the runway (2) and from an end (18) of the second arm (16) which is slidable along a guide (20) provided in the runway (2), the first arm (14) being hinged at the other end to the first upright (6) in a position such that a distance of the hinge pin (22) of the second arm (16)/second upright (10) from the hinging axis of the first upright (6)/second upright (10) corresponds to a distance of a hinging axis of the first arm (14)/second arm (16) from a hinge pin (28) of the first arm (14)/first upright (6),an actuator device (24, 26) having ends hinged on said hinge pin (22) and on said hinge pin (28) respectively, andat least one of the first/second uprights or first/second arm being provided with an elastic element (30) enabling it to vary the dimension between its hinged ends. 2. The lift as claimed in claim 1, wherein the first arm (14) is formed in two separate portions (14′, 14″) connected together by a hydraulic cylinder (30). 3. The lift as claimed in claim 1, wherein the elastic element is provided at that end of the second arm (16) slidable along the guide (20). 4. The lift as claimed in claim 1, wherein the elastic element consists of a slotted hole in which a lower end of the first upright (6) is hinged. 5. The lift as claimed in claim 1, wherein the elastic element consists of a wheel positioned at the end of the first upright. 6. The lift as claimed in claim 1, wherein the elastic element is inserted into the hinge pins of the first and/or of the second arm. 7. The lift as claimed in claim 1, the elastic element is of adjustable type. 8. The lift as claimed in claim 1, wherein the actuator device comprises hydraulic cylinder-piston units. 9. The lift as claimed in claim 1, wherein a flow synchronizer (32) is associated with the actuator device. 10. The lift as claimed in claim 9, wherein the flow synchronizer (32) comprises a control center (54) which feeds a hydraulic fluid to equal double acting cylinders (36) with parallel longitudinal axes, hinged at their bottoms to a fixed structure (34), rods (42) of cylinder pistons being hinged at their free end to a crank (44) rigid at its other end with a torsion bar (46) disposed perpendicular to an axis of the cylinders (36) and hinged to the fixed structure, hydraulic fluid outlets (54) of said cylinders (36) leading to hydraulic members for raising the lift. 11. The lift as claimed in claim 10, wherein bottoms (38) of the cylinders (36) are hinged to lugs (40) rigid with the fixed structure (34), with which hinging brackets (48) for a tension bar are also rigid.
