Operator’s Comfort is Foremost.

Wide Cab Exceeds Industry Standards.
Visibility
⍥Even more visibility than before, for safer, more efficient operating.

Excellent Ventilation
⍥Ventilation has been improved by the addition of the larger fresh air intake system,
and by providing additional air flow throughout the cab.
⍥Sliding front and side windows provide improved ventilation.
⍥A large sunroof offers upward visibility and additional ventilation.

Comfortable Operator Environment

⍥The control levers and seat can be adjusted to provide maximum operator comfort.
⍥The seat is fully adjustable for optimum operating position, reducing operator
fatigue.
⍥Console boxes slide forward and backward for improved accessibility.
⍥The proportional pressure controls reduce unnecessary exertion while ensuring
precise operation.
⍥Large windows allow excellent visibility in all directions.

Low noise design

⍥The Robex 7 series was designed with low operation noise in mind.
⍥Hyundai engineering helps to keep interior and exterior noise levels to a minimum.
⍥The cab's noise levels have been additionally reduced by improving the door seals
for the cab and engine compartments.
⍥An insulated diesel engine compartment with sound-damping material also
reduces noise.
