[. . . ] The proportional pressure controls reduce unnecessary exertion while ensuring precise operation. Large windows allow excellent visibility in all directions.
Low noise design
. The Robex 7A series was designed with low operation noise in mind. Hyundai engineering helps to keep interior and exterior noise levels to a minimum. [. . . ] The long undercarriage incorporates heavy duty excavator style components. An X-leg type center frame is integrally welded for maximum strength and durability.
Powerful and Precise Swing Control
Improved shock absorbing characteristics make stopping swing movement a precise and smooth action.
Track Rail Guides & Adjusters
Durable track rail guides keep track links in place. Track adjustment is made easy by using a standard grease operated cylinder track adjuster including shock absorbing springs. (Full Track Guide : Option)
