R 320 LC 7A Hyundai excavator specs & Dimensions (2007 - 2010)

Raise-up Wiper and Cabin Lights

Raise-up wiper installed to enhance a better front view. Cabin Lights enhance safety by brightly lighting the surroundings in dark environments. (optional)

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.

CUMMINS QSC Engine

The six cylinders, turbocharged, 4 cycle, Charger air cooled engine is built for power, reliability, economy and low emissions. This engine meets Tier III emissions regulations.

Top technology

The Quantum system engineered by Cummins and put in the QSC engine provides this power source with advanced electronics, higher torque and better throttle response. The shorter service times, longer maintenance intervals, increased fuel economy and decreased noise enable a better diagnostics so providing improved economic prognostics. The result is an engine that's a quantum leap ahead of both the C8.3-C and competitive power plants. The QSC is built to withstand the toughest work environment. Bearings have more surface area to handle higher loads with greater durability. 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.

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 re-starting during engine operation, even if the operator accidentally turns the start key again.

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 through error codes. This controller has the capacity to identify 48 distinct types of errors. The information from this device, such as engine rpm, main pump delivery pressure, battery voltage, hydraulic temperatures, and the state of all types of electric switches, provides the operator with an exact condition of the machine. This instrument makes it easier to troubleshoot the machine in case of failure.

One Touch Deceleration System

When the one touch deceleration switch is pressed, CPU controller controls the acceleration actuator to reduce engine speed to 700 rpm. Once this switch is pressed again, the engine speed recovers to its preset RPM.

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 actuated speed can be proportionally controlled.

Boom & Arm Holding System

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

Easy to Maintain Engine Components

The cooling and preheating system are provided for optimum and immediate operation, guaranteeing longer life for the engine and hydraulic components. Servicing of the engine and hydraulics is considerably simplified due to total accessibility.

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.

Excellent Ventilation

Ventilation has been improved by the addition of a 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 comfort for the operator. 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 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 cab's noise levels have been additionally reduced by improving the door seals for the cab and engine compartments. The use of an insulated engine compartment with sound-damping material also reduces noise.

Improved Intelligent Display

The instrument panel is installed in front of the RH console box. It is easy to check all critical systems with easy-to-read indicators.

Minimization of Shock and Vibration through a Cab Mounting System

The application of the Viscous Mounting System to the cabin support provides the operator with a smoother ride. The operator's work efficiency will increase as the shock and noise level in the cabin decreases.

Wide Cab with Excellent Visibility

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

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.

Easy-to-Reach Control Panels

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