Solar 420 LC-V Doosan excavator specs & Dimensions (2002 - 2007)

Simplified operation mode selection

The 3 work modes from the previous models have been reduced to digging and trenching modes for easy selection.Digging Mode: General Excavating, Ground Leveling, Loading Dump Truck, allows for versatility.Trenching Mode: trenching or excavating of side wall, operations which require heavy swing work.

Performance

This hydraulic excavator is equipped with the air-to-air intercooler engine, which has the greatest power output in its class and excellent fuel economy. It assures outstanding workability, productivity, and efficiency through the e-EPOS system, the new and improved version of EPOS SYSTEM. This will assure increase in operating capacity and decrease in fuel consumption.

Compatible with the European New Noise Control Requirements

To reduce the fan rotations and resulting noise, a large-capacity new fan blade has been installed. In addition, low noise muffler has been adopted to easily satisfy the new European Noise control requirements and improve noise levels.

Emergency throttle cable

In the event of engine speed control dial malfunction, emergency throttle cable mounted in the cabin can be used to manually control engine speed.

Heat shield panel for turbo charger

The heat shield guard has been installed over the turbo charger to prevent the operator from inadvertently touching the hot surfaces while checking the engine area.

Hydraulic system

e-EPOS (Electronic Power Optimizing System) allows the operator to maximize work efficiency over a full range of operating conditions and to minimize fuel consumption. Hydraulic system assures fully independent and combined operations. Automatic 2 speed travel system for high traction force and travel speed. Cross-sensing and fuel saving pump system. Auto idle system. 3-Working / 3-power mode selection system. Computer aided engine-pump control.

Filter / oil operating hour display

The hours in use for 9 filters and oils can be displayed so that replacement intervals can be easily recognized.

Hydraulic cylinders

High-strength piston rods and tubes are used. Cylinder cushion mechanism is provided for all cylinders to assure shock-free operation and extend life of cylinder.

Swing mechanism

High-torque, axial piston motor with planetary reduction gear bathed in oil. Swing circle is single-row, shear type ball bearing with induction-hardened internal gear. Internal gear and pinion gear immersed in lubricant. Swing parking brake is spring-set, hydraulic-released disc type. A two position swing lock secures the super-structure for transportation.

Drive

Each track is driven by an independent, high-torque, axial piston motor through planetary reduction gear. Two levers or foot pedal control provide smooth travel or counter-rotation upon demand.

Improved stability

Weight redistribution and increased swing radius (+190mm) improved dynamic stability and side lifting power. The stiffer frame of superstructure has greatly reduced structural vibration during operation.

Larger rubber pipe clamps

Larger size and improved material pipe clamps have been installed. This has resulted in noise reduction, increased vibration absorption and durability characteristics as well as preventing pipe cracks.

Strengthened Boom

Through stress analysis and endurance testing, the boom frame’s rear/central sections have been manufactured for the optimum life expectancy by using unibody casting to prevent cracking.

Arm Assembly

Critical components have been strengthened through stress analysis. All areas around the boss have castings and are reinforced resulting in additional durability and strength.

Reinforced Frame

Both boom and counterweight attaching sections have been reinforced to realize high-rigidity. As a result, the frame can support the long front and heavy attachments easily and ensure safe maneuverability. The right and left frame have been more stiffened by larger cross sections.

Controls

Pilot pressure control type. Right lever is boom and bucket control, left lever for swing and arm control.

Working Environment

Wide operator cabin space meeting the ISO Standards and expanded all-round visibility. The low-noise, low-vibration type comfortable cabin provides the operator with a safe and ergonomic operating environment.

Low Vibration Cab Mounting System

By using a total isolating seal design (full sealing), outside noise has been drastically reduced to levels comparable to those in a modern car. A viscous sealed mounting system has been incorporated, and the frame, cabin, and seat have been designed to absorb major and minor vibrations, resulting in a significant decrease in vibration felt by the operator.

Fresh Air Type Air Conditioner

One touch selector switch for the air conditioner and heater output, featuring a multi-vent circulation system that allows for greater cooling/heating performance. An improved front window defroster system has been added to provide enhanced clarity and visibility during any working condition.Easy replaceable air filter.Larger cool air intake vents.Industry standard fresh air/recirculation control system incorporated.Modular electric fan condenser compartment.

Large Handrail

The large handrail meeting the ISO Standards enables the operator to gain safe access to the section to be serviced.

Operator's Cab

A roomy, independent, shock and noise-free operator's cab with 4 side safety glass windows provides all-round visibility. The front window slides up and stores in the roof, while the side window can be left open for ventilation. It features a fully adjustable reclining seat: fwd./rev. and up/down, and a cab cooler option. ISO standard cab.
