Automatic digging brake

Activate the Auto Digging Brake function by pressing the button on the control switch. This function automatically holds the service brake when the vehicle stops (zero speed) without the operator stepping on the brake. When the transmission pedal is pressed, the brake is automatically released.

Undercarriage durability

A rigid, welded frame provides excellent durability. Efficient routing of hydraulic lines, transmission and rear differential protection and heavy-duty axles make the undercarriage perfect for wheeled excavator applications. An oscillating axle lock is available for digging and lifting operations.

Heavy-duty axles

The front axle offers wide oscillating and steering angles. The transmission is mounted directly on the rear axle for protection and optimum ground clearance.

Undercarriage

Extremely robust construction throughout – made of high-quality durable materials with all welded structures designed to limit stresses. Lateral chassis welded and rigidly attached to the undercarriage. Heat-treated connecting pins. Heavy-duty front axle with automatic or operator-controlled (on/off/auto) front axle oscillation lock.

Brakes

Dual multi-disc circuit with sintered metal discs for extended service life. Braking system activated by a pump and accumulator circuits. Automatic brakes for standard, released when pressing the transmission pedal. Spring-applied hydraulically released parking brake mounted on the transmission shaft.

Doosan buckets

4 More. More choice - More durable - More strength - More performance! The General purpose bucket is designed for digging and re-handling soft to medium materials (e.g. materials with low wear characteristics such as top-soil, loam, coal). The Heavy duty bucket is designed for mass excavations in dense materials such as hard packed clay, shot limestone, limited rock content and gravel. The Severe duty bucket is designed for durability in digging compact materials like loose or blasted rock, hard packed clay and stone. The X-treme duty bucket is designed as a long-life version of the Severe duty bucket for digging in the most abrasive materials.

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.

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.

Swing mechanism

The swing mechanism uses an axial piston motor, driving a 2-stage planetary reduction gear bathed in oil for maximum torque. Swing bearing: single-row, shear type ball bearing with induction hardened internal gear Internal gear and pinion immersed in lubricant Increased swing torque reduces swing time The swing brake for parking is activated by spring and released hydraulically.

Drive

The wheels are driven by a bent axial piston engine via a 2-speed powershift transmission. In addition to the 2-speed powershift transmission there is also an economy mode and a switch for the creep speed. A button makes it possible to pass from high to low in work mode. Two travel speed ranges offer a choice between increased torque or high speed.

Easy maintenance

Maintenance data are directly available from the control panel. Easy access to filters from ground level. To protect coolers and minimize downtime, the cooling compartment is equipped with fine mesh for the intake air. These innovations make maintenance operations a pleasure.

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. Cyclonic air pre-cleaner: air filter life and engine efficiency are directly related to the amount of debris ingested through the engine’s air intake. Therefore, a cyclonic air pre-cleaner (as 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.

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 a 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. The radiator and oil cooler have been separated, making access for cleaning easier. 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. An electric transfer pump for initial priming of fuel filters is featured as standard.

Adblue® tank

Connected to the ECU, sensors in the tank detect low levels of AdBlue® or any other system malfunction. To prevent over-filling during refilling, the machine is also equipped with an AdBlue® level indicator (LED light).

Centralized greasing points

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

Your safety is our priority

Rear and right side cameras as standard, anti-slip steps and platforms, as well as guard rails on upper structure. Optional: a 360° all-around view camera (AVM) for maximum safety while working with people around. Large side mirrors, 7 powerful LED work lights (4 additional lights possible as an option), travel alarm.

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.

Lifting Capacities

Lifting capacities are in compliance with ISO 10567:2007(E). The load point is at the end of the arm. The nominal loads are based on hydraulic capacity. The nominal loads shown do not exceed 75% of tipping loads or 87% of hydraulic lifting capacity. For lifting capacity with bucket, simply subtract the actual weight of the bucket from the values. The configurations indicated do not necessarily reflect the standard equipment of the machine.
