[. . . ] 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's engineers made efforts to keep interior and exterior noise levels to a minimum. [. . . ] The electronics with the QSB6. 7 have been proven with our high-horsepower productsworking in the harshest, most demanding environments-search as dusty, nonstop mining operations while meeting emissions regulations worldwide. The QSB6. 7 features 24 valve designed with centered injectors and symmetrical piston bowl. The combination of improved airflow and evenly dispersed fuel results in increased power, improved transient reponse and reduced fuel consumption. Increased Higher Performance Reinforced Bucket and Bucket Linkage To prevent excessive wear of pins and bushes, sealed joints have been applied. Bucket link design incorporates high durability and anti wear characteristics. Additional reinforcement plates on cutting edge section are welded. Thicker steel and an additional lateral plate are put in place to reinforce the bucket. Strong and Stable Lower Frame The reinforced box-section frame is all welded, with low-stress, high-strength steel. It guarantees safety and resistance against external impact when driving on rough ground and working on wet sites. The use of highly durable upper and lower rollers and track guards ensures proper machine transfer on all terrains. 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 Guide & Adjusters Durable track rail guides keep track links in place. Track adjustment is made easy by using a standard grease operated cylinder track adjusters including shock absorbing springs.
