Abstract
PURPOSE: To decrease an upward driving force by providing on one side of a cage a nut which is engaged with a screw shaft which is rotatably placed upright in a shaft, and attaching one end of a hanging rope to the other side, the hanging rope having a balance weight attached to the other end via a pulley. CONSTITUTION: A screw shaft 3 is rotatably placed upright inside a shaft casing wall 2, and the nut 4 of a bracket 5 on one side of a cage is engaged therewith so that the cage is raised and lowered by the rotation of the screw shaft 3. A hanging rope 7 is attached to a rope hitch 6 provided on the other side of the cage and a balance weight is secured to the other end of the hanging rope 7 via a pulley 8 freely rotationally attached to the casing wall 2. The weight of the balance weight is about half the weight and live load of the cage. Therefore, a conventional hoisting load is reduced to a quarter or less and a drive can be miniaturized.
