Product description:
SH520-9 hydraulic excavator has the characteristics of more efficient, more energy-saving and more environmentally friendly.SH520-9 hydraulic excavator potential energy recovery technology was shortlisted as one of the double-top ten national selections in the public announcement about the best energy-saving technology and the best energy-saving practice, and 13 patents were approved, which became one of the best energy-saving technologies in the field of construction machinery, and opened up a new era of energy-saving.
SH520-9 hydraulic 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 hydraulic excavator:
The same tonnage saves 15%-20% of fuel consumption, and improves the comprehensive efficiency by 20%-30%.

SH520-9 excavator reinforced work unit:
Reinforced movable arm, bucket bar：
1. High stress area → Use of high tensile strength steel plate
2. Shaft seat area: Use of forged parts
3. Middle section: Welding of large cross-section spacer plate
"Central load-bearing structure" on the shelf：
The "Central Load-bearing Structure" reduces stress by distributing the force directly to the chassis through the upper structure. Improves durability and extends machine life.
Reinforced "X" travel frame：
Reinforced design of the beam structure, where stress is concentrated, increases the strength of the cross-section by more than 35% compared to conventional models. It is more adaptable to severe working conditions and large loads.
Reinforced Bucket：
The wear-prone parts of the bucket (front, sides and bottom) are reinforced with super wear-resistant welded plates. The average service life of the bucket is more than 20% longer than that of the traditional model.
