An apparatus and method for lifting a spool of windable material including a barrel and two flanges whose rims engage the floor utilizes a ring having a diameter which is greater than the height of the flanges of the spool desired to be lifted. A strut spans at least a portion of the ring interior, and a carriage assembly which is cooperable with the spool barrel at one end thereof is mounted upon the strut for movement between first and second locations therealong so that by positioning the apparatus alongside one flange of the spool while the carriage assembly is positioned in its first location along the strut, placing the carriage assembly in cooperating relationship with the barrel of the spool, and then effecting the movement of the carriage assembly along the length of the strut to the second location therealong, the one flange of the spool is lifted from the floor.
