Excavator R450LC-7 is powerful highly productive machine designed for wide range of works.

The cab of crawler excavators Hyundai Robex of the series 7 is equipped in accordance of up-to-date requirements of safety, comfort and ergonomics. Large space of glazing ensure the excellent overview in all directions. The cab is equipped with air conditioner with improved air intake system which creates additional air flow in the cab. The seat on pneumatic suspension, the regulated control arms and the control desk allow to reduce fatigue loads and to increase the operator's work efficiency. All devices and controls of the excavator are located in such manner that the operator should not make excess movements when turning from one operation mode to another. Noise level in the cab was reduced due to application of improved door locks and sealants, engine compartment was coated with sound proof material. The excavator's cab is mounted onto the six shock absorbing supports that decreases vibration level inside the cab to the minimum one.

Hyundai excavators are equipped with Diesel non-emission engines Cummins with turbo charging and inter coller. Automatic power reduction system. When compensating valves are in neutral position for more than 4 seconds, CPU controller gives the signal to catalyst to reduce engine rotation speed to 1200 rpm. This results in reduction of fuel consumption. Power uptake control system. If this system is active the digging power increases by 10 %. It is especially useful, if there is need in power jerk. Automatic heating system. If engine's temperature after its starting is low, the CPU controller will automatically increase its rotation speed and flow in the pump. Thus, the oil is heated and the excavator's equipment is in rated operation mode.

Application of central lubrication system, accessibility of all units and modules make the Hyundai excavators to be undemanding and easy in maintenance. Newest electronic self-diagnostics system allows to control completely the excavator's condition.
