To provide a mobile lift usable for various cargo handling operations.SOLUTION: A mobile lift comprises: a body frame having a pair of guide posts; runners respectively provided on a caster 5 by which the body frame is supported so as to freely move and on the guide post, so as to be freely lifted/lowered; a cargo receiving table fixed to a runner lower part; and a lifting/lowering drive mechanism for liftingly driving the cargo receiving table. The lifting/lowering drive mechanism has: a pair of single-moving hydraulic cylinder sets 90A, 90B respectively accommodated in the pair of guide posts; a hydraulic circuit 100 for driving the cylinder sets 90A, 90B; and a power unit 130 for supplying hydraulic oil to the hydraulic circuit 100. The hydraulic circuit 100 has synchronous valves 121A, 121B by which respective flow rates of hydraulic oils in hydraulic oil delivery and return directions are made even relative to the pair of cylinder sets 90A, 90B.SELECTED DRAWING: Figure 8
