ABSTRACT:
An adjustable pad hydraulic lift structure has a vehicle engaging and supporting pad vertically movable by a hydraulic piston, the pad being mounted on a bolster and having load transfer blocks facing downwardly for engagement with the bolster to transfer vehicle load from the pad to the bolster. Supporting and guide rods on the bolster and bearings on the pad cooperate to support the unloaded pad for adjustment into selected position over the bolster, and while supporting the unloaded pad maintaining the pad at an elevation wherein the load transfer blocks are supported free of the bolster to permit free adjustments of the pad. The supporting and guide rods are yieldable when the pad is under vehicle load to permit the load transfer blocks to engage the bolster for load transfer from the pad to the bolster.
