Doosan dx800lc-7 crawler excavator

Lift your business to the next level with the DX800LC-7 Doosan excavator. Strong undercarriage, and the highest engine power and hydraulic flow in the market, with total control of the fuel consumption, to offer the lowest possible cost per ton.

Engine

Exceptionally powerful – with high torque at low revs – the Perkins 2506J engine combines reliability and low environmental impact. This Stage V compliant 6 cylinder engine delivers 402 kW at 1800 rpm.

Excellent fuel efficiency

The Smart Power Control (SPC) system increases fuel efficiency by adjusting the power to meet the application's needs. The system delivers the exact amount of oil needed to avoid any loss of energy.

Efficient fuel management

Choice of 4 power modes and 4 working modes guarantees optimum performance in all conditions. The Smart Power Control (SPC3) system reduces engine speed and adjusts pump torque according to work conditions. It automatically adjusts engine power and hydraulic output to improve fuel efficiency and reduce emissions. Additionally, the engine auto-shut-off feature shuts down the engine after the machine has been idling for a specified time, with the operator able to set the delay before shut-off via the touchscreen.

Advanced filtration

Fuel filters and water separator: a filter-type high-performance water separator effectively captures moisture in the fuel, reducing impurities and helping minimize any fuel-related issues. Pre-filters and dual main filters as standard achieve a high degree of purity that minimizes fuel system failures. The cyclonic air pre-cleaner, which is standard, is the first stage of an air intake system that prevents the majority of heavier-than-air particles from entering. Self-cleaning and maintenance-free, the system is able to expel all types of mixed debris, including mud, snow, rain, leaves, sawdust, chaff, etc.

Hydraulic System

The e-EPOS (Electronic Power Optimising System) is the brain of the excavator, minimizing fuel consumption and optimizing the efficiency of the hydraulic system for all working conditions. To harmonize the operation of the engine and the hydraulics, the e-EPOS is connected to the engine’s electronic control unit (ECU) via a data transfer link. The hydraulic system enables independent or combined operations 2 travel speeds offer either increased torque or high speed Cross-sensing pump system for fuel savings Auto-deceleration system 4 operating modes, 4 power modes Swing or boom priority selectable via a switch in the cab.

Safety

Your safety is our priority: 360° camera system, large side mirrors, Powerful LED work lights, anti-slip steps and platforms, guard rails on upper structure.

Easy maintenance

Automatic greasing system as an option, all filters easily accessible, compressor with air gun as option, everything designed for easy maintenance.

Maintenance access made simple

Large guard rails are installed along with anti-slip steps and plates, for safer, easier access to the whole upper structure.The air conditioning filter is placed on the side of the cab for easy access. The filter’s cover can be locked and opened with the starter key.A battery cut-off switch makes it easy to disconnect the battery for long-term storage.The hour meter display can be easily checked from ground level.Shut-off valves have been fitted on the pre-filter piping line and fuel tank drain piping to make servicing easier and prevent pollution from leakage.Engine parts can be easily reached via the top and side panels.2 large separated cooling compartments equipped with reversible fans as standard increase the cooling performance and simplify maintenance.For extra accessibility and servicing convenience, all filters (engine oil filter, fuel pre-filters, fuel filters and pilot filter) are located in the pump compartment.

Centralized greasing points

To make maintenance easier, the greasing points have been centralized. An automatic lubrication system is available as an option.

Extra-strong x chassis

Designed using finite element analysis and 3D computer simulation, the X-shaped undercarriage ensures optimum structural integrity and durability.

Undercarriage durability

Large chain composed of sealed, self-lubricating links for long-term dependability. For improved protection, alignment and performance, there is a full-length guard optional, according to the application. The track spring and idler are joined for long-lasting performance and easy maintenance. Cast steel heavy-duty sprockets guarantee the highest resistance. The track rollers are lubricated for life.

Undercarriage

Extremely robust construction throughout - made of high-quality, durable materials, with all welded structures designed to limit stresses. Track rollers lubricated for life Idlers and sprockets fitted with floating seals Track shoes made of induction-hardened alloy with double grouser Heat-treated connecting pins Hydraulic track adjuster with shock-absorbing tension mechanism.

Hydraulic Cylinders

High-strength steel piston rods and cylinder bodies. Shock-absorbing mechanism fitted in all cylinders for shock-free operation and extended piston life.

Drive

Each track is driven by an independent, high-torque axial piston motor through a planetary reduction gearbox. Two levers / foot pedals guarantee smooth travel with counter-rotation on demand. The track frame protects the travel motor, brake and planetary gears. The multi disc track brakes are spring-applied and hydraulic released.

Strengthened boom and arm

During the development of our machines, we use intensive testing to calculate the best load distribution throughout the boom structure. Combined with thicker material, this means that element fatigue is limited and both reliability and component life are increased. To better protect the base of the arm, reinforced bars have been added and the arm center and end boss have been strengthened.

Intelligent floating boom mode

The “intelligent floating boom” function allows the boom to move up and down freely according to the application:Hydraulic breaker setting: during boom down operation, the boom moves down freely under its own weight. The result is reduced shock and vibration and longer breaker service lifeFull float setting: during boom down selection, the boom is allowed to rise and fall as required while the bucket is drawn across the ground.

Comfort

One of the most spacious cabs in the market, with low noise & vibration levels and excellent all-round visibility. Fully adjustable heated air-suspension seat, air conditioning with climate control as standard.

First Class Comfort

Comfortably seated, you benefit from a clear all-round view of the worksite and have easy access to several storage compartments. Noise and vibration levels are remarkably low, while air conditioning and automatic climate control allow you to keep working for hours on end without feeling tired. Pedals, joysticks and armrests have all been designed for operator comfort and efficiency.

Cab Suspension

The cab’s suspension system (CabSus mount) dampens vibrations and provides outstanding protection against impact. This system absorbs shocks and vibrations much more effectively than a conventional silentblock suspension system.

Adblue Tank

Connected to the ECU, sensors in the tank detect low levels of AdBlue or any other system malfunction.

Versatility

5 front combinations possible to match all applications. Mass excavation front with large bucket size or heavy-duty fronts when more reach is needed.
