<p>A vehicle lift comprises a pair of parallel ramps (2) each of which is pivoted to an upstanding support (1) at one end, wherein the two ramps (2) are connected by a cross-beam (6) located towards the ends distal from the pivots (3) and rigidly secured to the ramps (2), which cross-beam (6) includes a lifting box (7) engageable with a lifting jack (12) and located substantially midway between the two ramps (2) such that lifting forces are directed through the centre line of the cross-beam (6). The cross-beam (6) bears against the ground when the ramps (2) are in a downwards position. The jack (12) can be replaced by axle stands (10) when the ramps (2) are elevated.</p> |
