ABSTRACT:
There is provided an apparatus for driving the raising and lowering of a lift for a tower type storehouse so as to supply a force for vertically operating the lift carrying goods to storerooms on every floor of the storehouse, and more particularly to an apparatus for driving the raising and lowering of a lift for a tower type storehouse, in which a plurality of hydraulic cylinder units are connected to each other along a vertical axial line so that the raising and lowering of the lift is achieved by the expansion and contraction of the connected hydraulic cylinder units due to the supply of hydraulic pressure, thereby uniformly supplying the hydraulic pressure to every hydraulic cylinder unit and assuring stability in the raising and lowering of the lift.
