  • Patent number: 6105938
    Abstract: An agricultural or floricultural elevation system is provided for lifting and supporting agricultural or floricultural products or containers at a desired elevation above the ground. The system includes a spool shaft and a drive assembly. The drive assembly is operable from a location below the spool shaft, and is adapted to selectively rotate the spool shaft axially in a first direction and a second direction. The elevation system further includes a plurality of first lines having a first end and a second end. The first ends are secured to the spool shaft so that when the spool shaft is rotated in the first and second directions, the first lines are wound and unwound, respectively, around the spool shaft. The system also includes a hanger rod that is secured to the second ends of the first lines to suspend from the spool shaft. In operation, a user secures agricultural or floricultural products or containers to the hanger rod.
