| Abstract: |
A portable hydraulic vehicle lift that functions as a vehicle trailer for transporting a vehicle over the road, and that includes a platform, and an elevating system for elevating the platform above the ground. The elevating system comprises a front leg assembly pivotally mounted on the platform that is pivotable between transport and lift positions, and a rear leg assembly pivotally mounted on the platform that is pivotable between transport and lift positions. A moving mechanism moves the front leg assembly between the transport and lift positions. A linking structure links the rear and the front leg assemblies for pivoting the rear leg assembly with the front leg assembly. Ground engaging wheels permit the platform to move over the ground and are mounted on the platform for elevating with the platform when the elevating system raises the platform such that the wheel are lifted from contact with the ground.
