Abstract: A semi-scissor lift includes a pair of vehicle loading plates parallel to one another, two pairs of lift units, each of which is configured to lift a corresponding vehicle loading plate, and a power unit configured to operate the two pairs of lift units. The power unit includes a number of hydraulic cylinder-piston assemblies, each having an end coupled to appropriate lift units. The number of hydraulic cylinder-piston assemblies includes a first hydraulic cylinder-piston assembly and a second hydraulic cylinder-piston assembly provided under different vehicle loading plates and at different sides thereof, and a third hydraulic cylinder-piston assembly provided under the same vehicle loading plate as the second hydraulic cylinder-piston assembly.
