[. . . ] 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 exhaust manifold allows for heat expansion and contraction, eliminating metal stress fractures. Reduced friction in the power cylinder means longer life and increased power output. From the structurally reinforced block to the stiffened gear housing, the QSC is built stronger to last longer. 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 Reinforced box-section frame is all welded using low-stress, high-strength steel. It guarantees safety and resistance against external impact when driving on rough ground or 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 adjuster including shock absorbing springs.
