Jack units (202) attach skates (204) to an object (210) to be moved. Each jack unit (202) has a tongue (218) that slidably engages a coupling slot (208) affixed to the object (210), and can be operated to raise or lower the tongue (218); when raised, the object (210) is supported on the skates (204) and can be rolled to a new location. A crane can attach to lift eyes (214) on the jack units (202) to allow the system (200) to be lifted with the skates (204) attached to the object (210), avoiding the risk to operators of positioning the skates (204) under the object (210) while it is suspended. Rotation-limiting structures (220) can be selectively employed to block rotation of the trailing skates (204) to facilitate steering when rolling the object (210) supported by the system (200).
