[. . . ] The proportional pressure controls reduce unnecessary exertion while ensuring precise operation. Large windows allow excellent visibility in all directions.
Low noise design
. The Robex new 7A series is designed with low operation noise in mind. Hyundai engineering made efforts to keep interior and exterior noise levels to a minimum. [. . . ] This decreases fuel consumption and reduces cab noise levels.

Mitsubishi D04FD-TAA Engine
The 4 cylinders turbocharged and charged air cooled, engine is built for power, reliability and economy. This engine meets EPA tier 3 and EUstage 3A emission regulation.
Reliability You Can Depend On
When you have a tough job to do you need the power, precision and flexibility of Mitsubishi D04FD-TAA engines. It features major enhancements to make every piece of equipment work harder, smarter, quieter and longer. The high Pressure Common Rail Fuel System provides enhanced engine performance with higher torque and better throttle response at every rpm without compromising fuel economy. The Mitsubishi D04FD-TAA engine is based on the highly successful Mitsubishi SK series engines. These engines combine proven full authority electronic controls with reliable performance you expect from one of the most successful and durable engine design.
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, lowstress, high-strength steel. It guarantees safety and resistance against external impact when driving on rough ground and working on wet sites through high tensile strength steel panels, with protection cover for transmission.
Powerful and Precise Swing Control
Improved shock absorbing characteristics make stopping swing movement a precise and smooth action.
Large Toolbox & Safe Footholds
Anti-slip footholds and wide toolbox improved safety and convenience.
