52 ton Hydraulic Excavator
1.It is heavy-load efficient and adaptable to multiple scenarios. Relying on the core power hydraulic combination with excellent key operation parameters, its heavy-load efficiency is 10%-15% higher than that of the same level, suitable for various heavy-load scenarios and sudden working conditions.
2.It is strong, durable and economical to maintain. With a reinforced structure and service life ≥10000 hours, its core components have low failure rate and convenient maintenance, greatly reducing fuel and operation costs.
3.It is intelligent, comfortable and safe to operate. Optimized power matching, comfortable and convenient cab, and complete monitoring and safety devices ensure safe and controllable operation.
As a core equipment for heavy-duty engineering, the 52-ton large-tonnage excavator is suitable for high-intensity scenarios such as mining and large-scale infrastructure. Its core configuration adopts the golden power hydraulic combination of Cummins QSM11 engine + Kawasaki main pump + Toshiba main valve, supplemented by reinforced structure and intelligent control, effectively solving the pain points of large-tonnage equipment such as wear, inefficiency and high energy consumption, and is the preferred equipment for large-scale projects.
Product diaplay:
Cummins engine, reliable, efficient, low fuel consumption：
1. adopts electronic control to electronically control the high pressure fuel injection in order to optimize fuel injection and reduce fuel consumption
2. reduces fuel consumption and noise by synchronizing control to reduce excess engine rotation under light operation.
INLINE main pump features：
1.high efficiency
2. high response
3. large displacement
4. abundant control methods
5. high power output density
6. high self-priming capability
7. high reliability
Toshiba Main Valve Functional Features：
1.linear travel circuit
2. boom priority, boom priority in compound action of boom and bucket
3. slewing priority, slewing priority in compound action of bucket slewing
4. bucket merge, standby merge circuit
5. bucket regeneration
6. boom regeneration
7. bucket, boom load holding valve.
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.
