Huge bale chamber - Huge performance
With a diameter of 2m and a width of 1.23m the resulting volume
of nearly 4m³
mean bale weights of up to 600 kg in wheat straw can be reached.
This is double that of some competitors.
The consequences:
o Baling time is drastically reduced.
o Fewer bales in the field.
o Standing time is minimal.
o Net consumption is reduced.
o Field clearing time is dramatically decreased.
Constant Pressure System
highest level of bale density.
In most variable chamber round balers the specific
pressure area at the bale surface goes down with the
increase of bale diameter, this means that with low power
low density is the result.
The bale chamber on the RP 502 / 520 is designed that the
specific pressure area on the bale surface is constant
from 1m to the set bale diameter up to 2m.
This is achieved by increasing the belt tension in
respect to the increase of bale chamber diameter.
Therefore a high compression of the baled crop is
achieved.
The hydraulic pressure for the density is produced by an
integral system so there is no connection between tractor
hydraulics and the baler for bale density.
This system gives simple settings of density with no pre
pressuring from the tractor and allows the bale to be
broken down in bedding or feeders right down to the bale
core. |

Special Compression Belts
Welger RP 502 / 520 balers are fitted with extremely
durable endless belts of virtually symmetric
construction. They have the advantage over conventional
belts as follows:
o Smooth running
o No joiners to hit belt guides
o High durability resulting in high bale densities
o Belt is unaffected if it turns over, same design both
sides
o High life span
Furthermore, due to the special design of the permanent
belt tension it is guaranteed there will be no problem in
starting any bale at normal working speed. |
