DEVELON

THE PIONEER

Crushing operation for mountains and forests and quick loading are possible. It is a standard product in the mining industry with high bucket capacity, large crushing hammer, increased operation speed, enhanced productivity, reduced fuel consumption, improved product quality, and better durability.
- With more potent engine with 14% additional power, careful control over enhanced energy efficiency has led to superior product quality and durability; thus improving parts versatility and compatibility. Moreover, the engine meets the tier-3 automobile emission standards as well as requirements for energy conservation and environmental protection.
- The state-of-the-art VBO hydraulic system electronically regulates the accuracy and responsiveness of the main pump, increasing the flow rate and reducing energy consumption by interrupting flow when needed.
- Adopting a low-fuel consumption design, the DX490LC-7B incorporate fuel-saving control technology known as SPC3 (Smart Power Control); thus achieving fuel efficiency surpassing that of the 7B Series.
- Parts requiring frequent maintenance have been strategically positioned for easy reach, with the human-centered design enhancing serviceability.
- Installation of protective fence at the lower section of the cab Front protective fence also available as an option.
- By significantly enhancing heat dissipation capabilities, cleaning and maintenance tasks are made easier.
- The strength and durability of the boom were enhanced by applying thick reinforced steel plates and high-strength casts.
- The durability of the arm was enhanced by increasing the thickness of the steel plate on the arm and using reinforcement bars and wear-resistant reinforcement steel plates.
- A reinforced bucket suitable for excavator tracks was selected to secure excellent durability in high-load working environments, enabling long hours of operation.

WE ARE BACK WITH NEW FEATURES

- The machine adaptability to low-quality fuel was greatly enhanced by improving the filtration performance of the fuel filter system and coating critical components with a material possessing excellent wear and corrosion-resistant properties.
- The DX490LC-7B can adjust the width of the crawler to match the requirements of the work environment, simultaneously offering safety when operating the equipment and convenience when transporting the equipment.
- Durability was improved by increasing the thickness of critical areas and adopting advanced manufacturing techniques.
- The upgraded cab offers good visibility, noise reduction, and outstanding convenience for the operator.
- By installing LED lights on the main frame, boom, and front of the cab, illumination for night operations has been enhanced significantly. This ensures the operator’s safety, convenience, and improved work efficiency during night-time operations.
- The expandable chassis structure—which is available as an option—optimizes the integrity of the x-frame, the joints on the left and right sides, and the upper central support. This chassis provides much needed reliability and stability in the work environment, especially during long operations.
- The ergonomically designed air conditioner is easy to operate, with strategically placed vents preventing frost build-up on the cab windows during the winter season.
- An automatic activation mechanism was added to the fuel heating function so that the fuel would be automatically heated in cold regions.

FUEL EFFICIENCY

Customer profitability is maximized through the adoption of low-fuel consumption design and installation of high-efficiency engine and advanced VBO hydraulic system, with the adoption of a more advanced version of SPC3 (Smart Power Control) technology enabling effective management of fuel consumption. Operators can choose from one of four working modes (P+,P,S,E) based on what the working conditions are like. When the operator activates SPC3 from the instrument panel, fuel efficiency can be optimized and fuel costs can be reduced effectively.
- The excavator uses an engine manufactured by SCANIA. With the installation of integrated pump and nozzle and unique centrifugal filter, the vehicle realizes high reliability, fuel efficiency, serviceability, low failure rate, and low maintenance and repair costs.
- Depending on the actual working conditions, operators have the option to select from Power Mode (P), Standard Mode (S), and Economic Mode (E). Through simultaneous smart control of automatic idling, main pump flow rate, and hydraulic system pressure, both power loss and fuel consumption levels are reduced.
- The SPC3 mode detects the load during actual working conditions and automatically adjusts the engine RPM and main pump torque, optimizing the swing system overflow. This enhances work efficiency for the operator while simultaneously reducing fuel consumption.
- The installation of a state-of-the-art electronically controlled hydraulic pump enables operators to control the vehicle precisely, resulting in faster completion times and significant improvements in work efficiency.
- The double rotation motor offers even greater torque, allowing the operator to carry out digging operations efficiently with precise control over the swing.

WORK PERFORMANCE

The DX490LC-7B comes with an even larger bucket (2.4-3.6m3) that provides increased productivity for the customers.
- The excavator is equipped with a handle boost button that instantly provides additional lift or travel power when activated. This feature enables the excavator to be used in challenging work environments with ease.
- The excavator’s motor has a rotational torque that is far superior to that of other excavators made by competing brands. This torque produces powerful rotations that enhance operational efficiency when performing combined work.
- By utilizing a device that delivers superior digging, traveling, and lifting power compared to its counterparts, the machine has enhanced its operational efficiency. Additionally, the implementation of a fuel blender that produces an optimal fuel mixture facilitates the seamless execution of combined work carried out with the excavator.
