ABSTRACT:
Tool for vertically lifting and maneuvering objects such as utility access covers. A pair of spaced-apart ring assemblies including inner and outer concentric independently rotatable rings are connected to each other by a first connecting member which extends over the object. The object is engaged to the tool by hooks suspended from the first connecting member. The ring assemblies are also connected by a second connecting member which is spaced from the first connecting member by a distance sufficient to permit a lever to be engaged to both connecting members so that when a force is applied to the lever, both connecting members move causing simultaneous rotation of the inner rings while the outer rings remain stationary, to vertically lift the object into the space between the ring assemblies. The object while suspended between the ring assemblies is then transportable by rotation of the outer rings with respect to the inner rings.
