Beschreibung
Zusammenfassung:	The utility model relates to a vertical pulling single crystal growing furnace draft tube automatic lifting device, including the bell, respectively the symmetry set up in two sets of elevating system of bell both sides and provide the drive mechanism of power for two sets of elevating system, single unit system horizontal installation is on the bell, and symmetrical balance is guaranteed to promote by the symmetric distribution. The synchronization that both sides promoted provides power by single motor and passes to another lift bar through the flexible axle with power by the commutator, guarantees the motion synchronism. It provides the asynchronous phenomenon of motion that power causes to have overcome each own motor of both sides. The utility model discloses possess characteristics rational in infrastructure, safe and reliable.
