2.Powerful digging force (same ton class upgrade)
Bucket digging force:292KN
Arm digging force:251KN
3.Agile slewing and shortened digging cycle time
Slewing speed:9.3r/min
4. Continuous operation time is greatly extended
Adoption of large-capacity fuel tank 650 L fuel tank
Excellent fuel saving performance extends working time by 20%.
Product description:
SH520-9 large excavator has the characteristics of more efficient, more energy saving and more environmental protection. Its excavator potential energy recovery technology was shortlisted in the national best energy saving technology and best energy saving practice announcement, and was approved 13 patents, becoming one of the best energy saving technologies in the field of construction machinery, opening a new era of energy conservation.
SH520-9 large excavator energy saving principle:
When the arm is falling, the oil in the large cavity of the arm enters the accumulator, and the energy is recovered and stored.
When the boom rises, the oil in the accumulator is converted into high-pressure oil and delivered to the boom cylinder, and the energy is released and utilized.
At this time, only one hydraulic main pump for the boom to rise, the other part of the flow is supplied from the accumulator, the conventional mode requires two main pumps at the same time to the boom cylinder oil supply.
Energy saving effect of SH520-9 large excavator:
The same tonnage saves 15%-20% of fuel consumption, and improves the comprehensive efficiency by 20%-30%.
