Overview
  • The Return of the Pioneer in Mining Excavation

    DEVELON's 30-ton class product is the company’s classic model in its product line up. It could be described as the original model in the crusher market. As the latest model in DEVELON's 30-ton category, the DX300LC-7B boasts



    a powerful engine and high fuel efficiency. It is widely used for small scale mining operations and large government construction projects.



    - The output power was enhanced 20% by upgrading the engine, ensuring superior operation performance.



    - The ACE hydraulic system in the DX300LC-7B was upgraded by increasing the discharge rate of the main pump in order to improve the amount of oil flow. This results in faster operation and greater load carrying capacity.



    - The hydraulic system was designed with low fuel consumption in mind through the adoption of the latest SPC (Smart Power Control) 3 system, resulting in a machine with an ideal fuel efficiency. The fuel saving effect is clearly apparent.



    - The real operating conditions at work sites were taken into consideration when developing the components. In order to increase the durability of key connecting components, single body casts were used. The machine promises excellent operational stability and durability with optimized chassis.



    - Due to organized and logical positioning of components, the operator can perform daily inspections while standing on the ground.



    - The recently upgraded SPC3 Smart Power Control System detects the power required in real working conditions and then automatically adjusts the engine rpm / main pump torque and controls the rotational operation. In this way the system enhances operational efficiency while reducing fuel consumption.



    - Depending on the actual working conditions, the operator could choose from Power Mode(P), Standard Mode(S), and Economic Mode(E). Through the simultaneous smart control of automatic idling, flow rate of the main pump, and hydraulic system pressure, power loss and fuel consumption levels were both reduced.

  • RELIABILITY

    Through upgraded design programming and repetitive simulations, improved reliability is achieved. The lifespan of the machine was extended through advanced 3D design and many iterations of reliable testing, creating even more values for our customers.



    - Taking into consideration conditions of a government construction site, DEVELON equipped the DX300LC-7B with a high-resolution rear-view camera which guarantees all-weather safety of equipment throughout the year.



    - By incorporating optimized structural design in certain harsh areas, the durability of the bucket was enhanced, and its lifespan extended.



    - The performance of the engine was improved by enhancing the fuel cooling capability to meet the temperature requirements of the engine.



    - Reliability was also improved with a 3-stage oil filter system that strengthens the performance of the oil filter. The machine ability to run on low-quality oil was improved, lowering the malfunctioning rate and significantly reducing the maintenance costs.



    - Through improved structure and welding techniques, stress concentration is reduced. By improving the structural stability and durability of the arm and boom with thicker plates in critical areas, the machine’s adaptability to harsh working environments was enhanced.



    - The durability of the cylinder in the front of the machine was increased, resulting in lower maintenance and repair costs. This improvement allows owners to operate the machine for longer periods for jobs that require continuous digging.
