6.19.4 Instruction on piles creation (with the ROPA loader)
During lifting, ensure the correct soil content of the beets. A little amount of soil (soil
content around 10-15%) protects the beets during loading. If the soil content is too
high the beets cannot be loaded so quickly.
If sugar beets are loaded immediately after lifting they should be cleaned as much as
possible by the beet harvester. If freshly lifted beets are cleaned at loading this will
more often cause damage to the beet body than with beets deposited for a while.
In case of very light soil, which can easily be strained, you should include a low soil
content in the beet pile at lifting. This soil content has a certain damping effect during
loading, which largely protects the beets from damage, but can be removed without
any problem by ROPA cleaner-loaders .
Especially in case of sticky soil, after lifting usually a large soil content is still sticking
to the beets despite good cleaning. These sugar beets should be deposited in piles
for at least 3-5 days before loading and 'kept dry' during this period. In case of moist
weather, cover these piles if possible, so that soil residues will start to dry off. Dried
soil has a certain damping effect during loading, but can also be excellently cleaned
off using ROPA cleaner-loaders.
In case of very difficult ground conditions, an optimal cleaning effect may only be
achieved if the beets are deposited in piles for at least 5-7 days and are “kept dry” dur-
ing this period. The same holds true if the soil content is sticking very much to the beet
body after lifting. For these beets, you will only achieve a high throughput during load-
ing and beet-sparing loading if the soil content has started to dry on the beet body.
Only deposit beet piles on dry and trackless soil, if possible. The ground should be as
free as possible of foreign bodies like stones, wooden parts, etc.
If the estimated soil content of a pile is 25% or greater the pile height should not
exceed two metres, if possible. For this pile height, you will achieve high throughput
with simultaneous optimum distribution of soil cleaned off during loading. Long and low
piles can usually be loaded faster than short and high ones.
Take note of our plans for depositing piles. In any case, comply with the distance to
the transport path. When making a pile ensure that the pile width does not exceed
the width of the pickup of the cleaner-loader used. The pickup widths of ROPA euro-
Maus3 is eight metres and ROPA euro-Maus4 and Maus 5 is ten metres.
Loading is usually performed to the right. Please consider this when making the pile.
Due to technologically mature engineering of ROPA cleaner-loaders loading to the left
is also possible with the same throughput and the same quality.
