Why does my JOBO Lift look like it is
missing a transfer gear?
In 1995 JOBO began producing a slightly
changed lift arm for both its AutoLab processors and its JOBO Lifts. It is most easily
recognized by its black tank retaining clips. In the older lift arms, the tanks were held
in place by white retaining clips.
In the Autolabs
2000, 3000, and now 2200, 2300, 2400 and 2500, we began using 2 transfer gears (the small
white gear in the lift arm which turns the tank) in order to improve the way the processor
handled 3000 series drums. But this also requires that the rotation motor completely stops
turning as the lift arm raises up, and the motor remains stopped until the lift arm
returns to its horizontal position. New circuitry was needed to accomplish this.
Since we use essentially the same tool to
mold both the AutoLab lift arms and the JOBO Lifts for
manual processors, there is a space for two transfer gears in the manual JOBO Lift.
However only one gear should ever be used! Since the motor system on the manual processors
continues to turn the main drive cog using two gears would cause major clashing of the
gears as the lift arm is lowered. Ultimately this would cause premature aging of the lift
motor and the gears.
