A vacuum-controlled apparatus for gripping or gripping and lifting a load such as a roll-out refuse container. The lifting apparatus includes a primary vacuum pad for initially engaging the load, the primary vacuum pad comprising a vacuum head for exerting a vacuum-induced suction grip on the load, secondary vacuum pad carried by the vacuum head for secondarily engaging the load and supplementing the vacuum-induced grip on the load. A lifting arm effects vertical movement of the load. The vacuum pads are resilient and have a load-contacting surface on one side thereof generally corresponding to the shape of a surface of the load to be contacted by the load-contacting surface.
