All the outer parts of the housing are made of steel and are of the simplest possible construction, so if they are damaged, those elements can be easy repaired and new components will cost less in the event of major damage.


The cab is designed as a separate module, so it is completely enclosed in construction. For this reason, there is more pressure inside the cab than outside when the machine is running. There is less dust inside the machine, the sound level in the cab is lower and the ventilation system works efficiently. All this gives the operator better working conditions and has a positive effect on productivity.
