Spacious and Convenient Cab

The newly designed cabin was conceived for more space, better visibility and increased
operator’s comfort. The front window is curved with 17% more glass area than our previous
series. Special attention was given to a clean and open interior with plenty of visibility on
the machine surroundings and the jobsite. A balanced combination of cab ergonomics
puts the operator in the perfect position to work safely and securely. The full automatic
temperature control features 11 air vents and increased cooling and heating capacity for
optimum temperature control. The defroster vents on the front and rear window and an
electric pre-heater make working in cold circumstances more convenient.
