52 Ton Large Excavator
The 52-ton large excavator is a highly efficient and powerful heavy-duty machine. Its adjustable undercarriage design provides excellent stability during operation and makes transportation between sites much easier. Equipped with an upgraded hydraulic system, it delivers stronger digging force and faster swing speed than most models in its class, helping to complete tasks more quickly. With a large fuel tank and advanced fuel-saving technology, it can work longer without frequent refueling, making it ideal for demanding jobs like mining and major earthmoving projects.
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%.
