The complete lifting unit (shaking shares, paddle, depth-control shaft, lifting rollers,
pinching roller) is driven hydraulically.
Applied to all lifters:
Lifting rollers one to six are driven by the left front lifter gear unit. The two short lifting
rollers on the right are driven by the right rear lifter gear unit.
The two short lifting rollers on the left are driven by the left rear lifter gear unit. For all
lifters the direction of rotation of the last lifting shaft can be changed from the driver’s
seat. This gives a pinch roller effect. This improves the cleaning result.
The operating depth of the lifting shares in the ground (share depth adjustment) and
the distance of the lifting rollers from the ground (height adjustment of the roller move-
ment) can be conveniently set from the driver's seat.
Power is transferred between the drive and the long lifting rollers via a polyamide plug-
in connector. The plug-in connector is screwed into the left end of the roller for all lift-
ing rollers.
As optional equipment, the lifter may be fitted with lifting shafts having a larger diame-
ter than the standard shafts. This largely avoids beet losses for small sugar beets. But,
simultaneously, soil separation in the lifter is reduced.
The depth-control shaft guides the lifting shares to the depth set and simultaneously,
using the forced intake (three stable rubber paddles for each row of beets), supports
the sugar beet flow from the shares to the lifting rollers.
The depth-control shaft is hydraulically driven on both sides. The speed of the depth-
control shaft depends on the driving speed, but may be changed by the driver.
