Low Fuel Consumption And High Efficiency
1. Adopting the original imported engine for high adaptability of environment
Equipped with Cummins' high-power QSX15 engine, its unique ECO mode and hydraulic system ensures excellent fuel efficiency;
2. Vibration damping and noise reduction
Adopting the existing high-performance shock absorbers, combined with the design of the covering partitions, it is equipped with a sealed powerhouse and optimizes vibration and reduces noise in the form of a larger radiator etc.
3. It's equipped with a low-temperature high-capacity battery with strong cold-start capability.
Double Pumps, Potential Energy Recovery Of Boom Cylinders
1. Potential energy recovery of boom cylinders
It is equipped with potential energy recovery system and customized CCHC spool to optimize the regeneration circuit of the main valve boom; at the same time, it is equipped with bypass system of the big chamber of the bucket cylinder, big chamber of the bucket cylinder, and small chamber of the movable arm cylinder of the working device, which reduces the energy loss;
2. Hydraulic system
(1) It adopts 280cc large-displacement serial-connected double pumps, with large system flow rate and fast operation speed;
(2) Adopting a large diameter hydraulic main valve, it features low system pressure loss, high efficiency and low fuel consumption;
(3) High torque rotary motor for fast rotary start-up;
Heavy-Duty Reinforced Design Of Structural Components With A Robust Appearance
1. The structural parts are designed by finite element analysis for heavy-load reinforcement, improving the loading capacity by 15% compared with models of the same tonnage in the industry;
2.SC8050.9 is equipped with 4m³ rock super bucket as standard, which is made of double-layer high-strength wear-resistant plate. It can be equipped with a variety of buckets such as 3.5-5.5m³ buckets for rocks and earth, while various fittings such as looseners and loosening buckets can be added to meet the demands of various working conditions;
Operational Comfort, Intelligent And Humanized Design
1. Adopting a newly designed positive-pressure cab with full protection as standard, large space and high safety, its sealing is 70% higher than the same class, which effectively isolates dust and significantly reduces the noise inside the cab;
2. The cab features novel appearance, comfortable control, wide field of vision, intelligent and humanized design.
Unique Styling And Robust Appearance For Easy And Quick Maintenance
Each type of filter element is designed externally, which makes overhauling and maintenance more convenient.
