A dolly for lifting and carrying dead sows and the like from and in confined spaces, respectively. A platform on castors with a vertical back has a removable pulley, at their adjoinment, through which a cable first pulls the sow horizontally onto the platform and then vertically, after the pulley is removed, along the vertical back. The cable is pulled by a winch attached to the rear side of the vertical back.
