ABSTRACT:
A lifting device for lifting and dumping refuse receptacles into the cavity of a refuse collection vehicle. The lifter has upper and lower engagement members movable between first and second spaced apart positions for capturing the receptacle lifting handles to lift and invert the receptacle without unduly spreading apart the handles. The lower engagement member of the lifter is movable and resiliently biased in an extended position so as to yield upon contact with the common exterior wall of the refuse receptacle.
