6.12 Lifting
6.12.1 Preparation for lifting
Familiarise yourself with the local ground and landscape before starting to work.
Get an overview of the field of beets to be lifted and determine the best place for set-
ting up the pile.
Instruct the people present before starting to work about the most important safety
regulations, especially the required safety distances. In any case, instruct all people
that you are obliged to immediately stop the machine and to immediately cease work if
any one enters the hazard zones.
– Switch to operating mode "Field".
– Swing out depth-control wheels (not with R*SU).
– Swing down leaf sensor.
– Swing out leaf-spreader (only with RBS and RAS).
– Unfold bunker with the help of automatic folding.
6.12.2 Lifting process
– Drive into the field slowly and carefully so that the machine is in line with the row
counted.
– Preselect lifting through steer.
– Switch on machine drive.
– Set the min. and max. lifting speed (menu "Main settings", submenu "Others").
– Make the basic settings for the cleaning elements (infeed conveyor, strainer
wheels).
– Lower three-point suspension and drive into the field.
– Immediately adjust defoliator height and lifting depth to the situation. Ensure in
doing so that the beet leaf is topped a little above the beet crown and the sugar
beets are lifted from the ground completely.
– Check the setting of the scalper, in case of need, reset it.
– Check, by looking into the beet bunker, whether lifting is performed in the desired
quality. If not, immediately correct the corresponding settings.
– Check, by regularly looking into the lifting unit, whether the machine cleanly drives
within the row. If this is not the case, re-steer the rear axle so that the share bodies
are always in the centre of the possible shifting range, if possible.
Normally, first the headland is lifted and room for the pile created. Then, the field
is lifted through once to obtain enough manoeuvring space. The exact procedure
depends, as already mentioned several times, on the local conditions. In this case, the
expert knowledge and skills of the driver alone influence the lifting results.
During lifting, the sugar beets are stored in the bunker. Two ultrasound sensors in the
front bunker wall (1) and the rear bunker grid (1) detect the filling level of the bunker,
and in case of need, switch the rotating direction of the auger to fill up the bunker as
evenly as possible. When the bunker is filled up, the sugar beets must be unloaded
either onto a transport vehicle driving alongside, or deposited in a suitable place in the
form of a pile.
