Гусеничный экскаватор 210LC-7.
210LC-7Built for Maximum Power, Performance, Reliability.
Operator’s Comfort is Foremost. Wide Cab Exceeds Industry Standards.

Visibility.
Even more visibility than before, for safer, more efficient operating.

Excellent Ventilation.
Ventilation has been improved by the addition of the larger fresh air intake system, and by providing additional air flow throughout the cab.
Sliding front and side windows provide improved ventilation.
A large sunroof offers upward visibility and additional ventilation.

Comfortable Operator Environment.
The control levers and seat can be adjusted to provide maximum operator comfort.
The seat is fully adjustable for optimum operating position, reducing operator fatigue.
Console boxes slide forward and backward for improved accessibility.
The proportional pressure controls reduce unnecessary exertion while ensuring precise operation.
Large windows allow excellent visibility in all directions.

Low noise design.
The Robex 7series was designed with low operation noise in mind.
Hyundai engineering helps to keep interior and exterior noise levels to a minimum.
The cab's noise levels have been additionally reduced by improving the door seals for the cab and engine compartments.
An insulated diesel engine compartment with sound-damping material also reduces noise.

Wide Cab with Excellent Visibility.
The cab is roomy and ergonomically designed with low noise level and good visibility. A full view front window and large rear and side windows provide excellent visibility in all directions.

Highly Sensitive Joystick and Easy Entrance.
New joystick grips for precise control have been equiped with double switches. (Left: Power boost / One touch deceleration, Right: Horn/Optional).

Easy-to-Reach Control Panels.
Switches and other essential controls are located near the operator. This helps keep operator movement to a minimum, enhancing control with less operator fatigue.

Wide, Comfortable Operating Space.
All the controls are designed and positioned according to the latest ergonomic research. Reinforced pillars have also been added for greater cab rigidity.

Minimization of Shock and Vibration through Cab Mounting System.
The application of Viscous Mounting to the cabin support provides the operator with a much improved ride. The operator work efficiency will increase as the shock and noise level in the cabin decreases.

Improved Intelligent Display.
Instrument Panel is installed in front of RH console box. It is easy to check all critical systems with easy-to-read indicators.

Raise-up Wiper and Cabin Lights.
Raise-up wiper has enhanced for the better front view. Cabin Lights enhances safety by brightly lighting the surroundings during night work(optional).

Rear Emergency Exit Window.
Rear Exit Window is designed with easy exit for operator's safety.

Drink Holder and Magazine Box.
The New Cab has even more space for the operator. An Additional storage box is located behind operators seat, and it keeps food and beverages cool or hot.

Advanced CAPO System.
The Advanced CAPO(Computer Aided Power Optimization) system maintains engine and mutual pump power at optimum levels. Mode selections are designed for various work loads and maintaining high performance while reducing fuel consumption.
Features such as auto deceleration and power boost are included in the system. The system monitors engine speed, coolant temperature, and hydraulic oil temperature. Contained within the system are self diagnostic capabilities which are displayed by error codes on the cluster.

Self Diagnosis System.
The CPU controller diagnoses problems in the CAPO system caused by electric and hydraulic malfunctions and displays them on the LCD monitor of the cluster by error codes. This controller has the capacity to identify 48 distinct types of errors. As the information from this device, such as engine rpm, main pump delivery pressure, battery voltage, hyd. temperature, and the state of all types of electric switches, provides the operator with a much more exact state of machine operating condition.
This makes the machine easier to troubleshoot when anything does go wrong.

Arm Flow Regeneration System.
Arm flow regeneration valve provides smooth arm-in operation without cavitation.

Boom & Arm Holding System.
The Holding valves in the main control valve prevents the boom & arm from dropping over an extended period in neutral position.

Auto Deceleration System.
When remote-control valves are in neutral position more than 4 seconds, CPU controller reduces engine speed to 1200rpm. This decreases fuel consumption and reduced cab noise levels.

One Touch Decel System.
When the one touch decel switch is pressed, CPU controller controls the accel actuator to reduce engine speed to low idle rpm. And then the one touch decel switch is pressed again, the engine speed recovers.

Max. Flow Cut-off System.
For precise control and finishing work, the Max. Flow Cut-off System reduces pump flow, thus allowing smooth operation.

Automatic Engine Overheat Prevention.
If the engine coolant temperature gets too high, the CPU controller lowers the engine speed and cools the engine.

Anti Restart System.
The new system protects the starter from restarting during engine operation, even if the operator accidentally turns the start key again.

Power boost control System.
When the power boost system is activated, digging power increases about 10%. It is especially useful when extra power is temporarily needed, for instance, when digging hard earth and rock, or if the bucket teeth are stopped by a stubborn tree root.

Automatic Warming-up System.
After the engine is started, if the engine coolant temperature is low, the CPU controller increases the engine speed and automatically to warm up the engine more effectively.

Pump Flow Control System.
In neutral position: Pump flow is reduced to a minimum to eliminate power loss.
In operation: Maximum pump flow is delivered to the actuator to increase the speed. With movement of the control lever, pump flow is automatically adjusted and the actuator speed can be proportionally controlled.

Hydraulic Damper in Travel Pedal.
Improved travel controllability & feeling by shock reducing when starting and stopping.

CUMMINS B5.9-C ENGINE.
The six cylinders, turbo-charged, 4 cycle, charger air cooled engine is built for power, reliability, economy and low emissions.

A More Reliable Way To Reach You Dream.
The Cummins B5.9-C engine has been designed with 40% fewer parts than the competition. That means there's less that can go wrong when you need it most. It also means fewer parts to inventory. Repairs are simplified because no special tools are needed for maintenance. The weight of the machine is reduced without sacrificing strength.
The B5.9-C engine is capable of reaching emission standards without electronic engine controls. You get a proven power plant that meets ecological concerns, without paying a premium for technology you don’t need.

Reinforced Bucket and Bucket Linkage.
