1. Powerful power system
Usually equipped with turbocharged diesel engines such as Doosan DB58TIS or Cummins QSM11 (depending on production year and region).
The engine power is approximately 190-220 kilowatts (about 255-295 horsepower), providing surging power that can easily handle tasks such as heavy excavation, crushing, and material handling.
Common rail fuel system (if any): improves fuel atomization effect, brings better fuel economy and lower emissions.
2. Efficient and advanced hydraulic system
By adopting an electronic hydraulic system, more precise flow and pressure control can be achieved, improving operational efficiency and smoothness of movement.
Power mode switching: Multiple operating modes are usually provided (such as power mode, standard mode, and economy mode), and users can choose according to their operating needs to optimize performance and fuel consumption.
Good coordination of movements: Smooth compound movements can be achieved between the boom, arm, bucket, and swing movements, improving work efficiency.
High pressure, high flow rate: capable of driving various large-scale operating equipment, such as heavy-duty buckets, breakers, hydraulic shears, etc.
3. Excellent homework ability and stability
Typical bucket capacity: approximately 1.40-2.00 cubic meters.
Maximum excavation depth: approximately 6.5-7.0 meters.
Maximum excavation radius: approximately 10.0-10.5 meters.
Maximum unloading height: approximately 6.5-7.0 meters.
Long chassis (L): Provides a larger grounding area, significantly improving the stability and passability of the machine on soft ground, muddy areas, or slopes, reducing the risk of sinking.
Durable and sturdy walking device: heavy-duty tracks, chain wheels, idler wheels, and supporting wheels that can withstand the impact and wear caused by heavy-duty operations.
4. Durable and sturdy structural components
High strength boom and arm: using advanced welding technology and high-strength steel, capable of withstanding huge excavation and impact forces.
Reinforced cab: Provides excellent safety protection and complies with ROPS/FOPS standards.
Heavy duty frame and rotating platform: ensuring the overall stability and durability of the machine under harsh working conditions.
