A wheeled hydraulic jack with a suspensory lifting device comprises a hydraulic unit, two pivotal cantilever arms and two movable tension links each pivotally mounted on each of the pivotal cantilever arms. The free end of each movable tension link is connected with one end of a cross-wise shaft of the hydraulic unit. A piston of the hydraulic unit moves upwardly and bears against the cross-wise shaft to lift a loading terminal of the pivotal cantilever arms by a suspensory device.
